what does known traveller number mean

Known Traveler Number program: What is it, and should you get 1?

Editor's Note

When you travel, there are a few pieces of information you probably like to keep handy, including your frequent flyer number, your passport number and your trip confirmation number.

However, another number comes into play if you have TSA PreCheck or Global Entry : your Known Traveler Number. It's an important number that ensures access to the TSA PreCheck lanes .

Here's what to know about getting a KTN, how to find it and how to ensure it's attached to your flight reservations.

What is a Known Traveler Number?

A KTN is a nine-digit code each TSA PreCheck and Global Entry member receives from the U.S. Department of Homeland Security upon approval for one of those two programs. Members of a couple of other Trusted Traveler programs get a KTN as well.

The code may be a combination of both letters and numbers. It's your identification number that proves you're a member of one of these programs and shows that you are eligible to use the TSA PreCheck lanes at U.S. airports.

Travelers with a KTN have gone through an application and screening process , and they are known and recognized as travelers by the U.S. government.

Should you apply for a Known Traveler Number?

Getting a KTN is helpful for air travel because if you have one, it means you're a member of a program that gets you shorter wait times.

A KTN is your key to access the TSA PreCheck lanes. These lanes typically have shorter lines and allow members to undergo a less intrusive screening process than the standard lanes. About 99% of TSA PreCheck customers wait 10 minutes or less at security, according to the Transportation Security Administration.

There are several ways to get a KTN through different Trusted Traveler programs run by the DHS. Each program requires travelers to submit an application and go through an interview process. Those interviews generally occur in person at enrollment centers for first-time applicants, with many enrollment centers located at airports. The government is allowing virtual interviews for certain applicants, often those seeking to renew their membership.

Each program that provides travelers with a KTN has a fee, and memberships in all programs are valid for five years. Many credit cards also offer application fee credits for Global Entry or TSA PreCheck .

TSA PreCheck

If you've applied for TSA PreCheck, gone through the screening process and received confirmation of your approval into the program, you'll receive a KTN from the government.

TSA PreCheck offers a fast-tracked security experience for its members. When going through the TSA PreCheck lanes, you generally won't have to remove your shoes, take laptops or liquids out of your bag, or go through the full-body scanner.

The application fee is $78 for first-time applicants.

Global Entry

If you've received your TSA PreCheck membership by applying for Global Entry, you'll receive your KTN through your Global Entry membership.

Global Entry is a U.S. Customs and Border Protection program that allows travelers designated as low-risk by the U.S. government to use faster customs lines when returning to the U.S. from abroad. Members also get access to TSA PreCheck.

The fee for an application to this program is $100.

If you're planning to travel internationally and within the U.S. multiple times in the next five years, Global Entry is probably your best bet since it gets you expedited screening both at customs and at TSA checkpoints for only $22 more than a standard TSA PreCheck membership.

Nexus and SENTRI

The DHS has two other Trusted Traveler programs for travelers entering the U.S. from Canada and/or Mexico. Nexus and SENTRI also provide members with TSA PreCheck access and, thus, a KTN.

Nexus allows pre-screened travelers to use expedited processing when entering the U.S. from Canada by air or land. The fee for this program's application is $50.

SENTRI allows pre-screened travelers expedited entry into the U.S. from Canada and Mexico by air, land or sea. The application fee for this program is $122.25.

How do you add a Known Traveler Number to your travel bookings?

Once approved for TSA PreCheck, Global Entry, Nexus or SENTRI, you'll have to follow one additional step to ensure "TSA PreCheck" is printed on your boarding pass: You have to attach your number to your airline profile.

If you're just looking to attach your number to a single reservation, you can typically do this when filling out your personal information at checkout when booking a flight. However, we recommend always flying with a frequent flyer account to earn miles .

If you have a frequent flyer account, you can attach your KTN right to the personal information section of your airline profile. Once you do this, your KTN should be automatically added to each booking you make with that airline, as you include your frequent flyer number on the reservation. You typically can add your KTN to an existing reservation, too.

What to do if you forgot to add a KTN to your flight

If you already booked a flight and forgot to add your Known Traveler Number to your reservation, don't fret. You should be able to easily pull up your reservation and add your KTN.

Go to the airline's website or mobile app. Pull up your reservation using the confirmation number (or record locator) the airline gave you when you booked your trip. Then, go to the traveler information section. There should be a line that says "Known Traveler Number," "KTN" or "Secure Traveler Information." That's where you put your KTN.

If you've already checked in for your flight and downloaded your boarding pass, you may need to re-download the boarding pass to see "TSA PreCheck" appear.

Where can you find your Known Traveler Number?

The time when you'll most likely need your KTN handy is when booking a flight or updating your airline profile. This goes for new members of TSA PreCheck, Global Entry, SENTRI or Nexus, as well as existing members who might be flying with an airline for the first time since joining one of those programs.

With all the numbers, passwords and accounts we have to keep track of in our lives, it's easy to lose your KTN ... and most of us probably don't know our number by heart. Fortunately, there are a few ways to locate it.

If you're a standard TSA PreCheck member looking to track down your number, you can use this page from the DHS to put in your personal information and look up your number.

If you received your KTN through the Global Entry program, you have a couple of options. If you have your physical Global Entry card, check the backside. Your nine-digit "PASSID" is your KTN; it may start with "15," "98" or "99."

Another way to locate your Known Traveler Number is to log in to your Global Entry or other Trusted Traveler Program account. There, you should be able to see which program you're enrolled in, as well as your membership number/PASSID, which, again, is your KTN. You should also be able to see when your membership expires.

An additional option for tracking down your number is to check your frequent flyer account for an airline you've recently flown with. If your membership in one of the Trusted Traveler programs is active and you've used TSA PreCheck before, odds are your KTN is on file with one or more airlines you regularly fly.

For this option, you'll need to go to your airline profile. If your KTN is in your profile, you should see it listed under your personal information.

Bottom line

A Known Traveler Number is a code that gets you into the TSA PreCheck lane. It's how the airline and government recognize a trusted traveler who is a member of TSA PreCheck, Global Entry or other similar programs.

Keep your number handy and add it to your airline profile. If you're not a member, consider enrolling in one of these programs that gives you a KTN and makes your trip through the airport less of a hassle.

If you’re new to TSA PreCheck or Global Entry, you may be wondering what a Known Traveler Number (KTN) is, how it works, and why there’s a KTN box when booking flights, but there isn’t one for your TSA PreCheck or Global Entry number. Here’s what you should know about your KTN.

What Is a Known Traveler Number?

Your Known Traveler Number is your membership number with a Trusted Traveler Program. This number is what allows you to access TSA PreCheck security lanes and Global Entry lanes (depending on which Trusted Traveler Program you join).

How To Get a Known Traveler Number

To acquire a Known Traveler Number, you must participate in one of the Trusted Traveler Programs. These are:

• Global Entry
• TSA PreCheck

Global Entry and TSA PreCheck are by far the most popular options in the U.S. The NEXUS and SENTRI programs also provide a Known Traveler Number, though these programs are much less commonly used in the U.S.

Credit Cards That Reimburse for Global Entry, TSA PreCheck, and/or NEXUS Application Fees

Many premium credit cards will reimburse you for the application fee for either Global Entry or TSA PreCheck (including American Express, Capital One, Chase, and Citi, which all provide cards that offer an application fee reimbursement).

Since several cards offer this benefit, consider the other benefits of your credit card options before you choose one. Look at the points they earn, trip delay protection, purchase protection, elite status, or airport lounge access.

If your priority is earning tons of valuable (and transferable!) points, you might choose the Chase Sapphire Reserve card . It earns 5x points on air travel and 10x points on hotels and car rentals when you purchase travel through Chase Travel, 10x points on Lyft (through March 2025), 3x points on all other travel, and it comes with a Priority Pass Select membership for lounge access. You’ll also receive a $300 travel credit that is automatically applied to your first $300 in travel purchases each cardmember year (this includes taxis, Uber , Lyft , train tickets, flights, hotels, and more).

If airport lounge access and elite status are your top priorities, the Amex Platinum card and Amex Business Platinum card provide world-class lounge access , including Centurion Lounges and Delta Sky Clubs (when flying Delta), on top of a Priority Pass Select membership upon enrollment. Cardholders also receive elite status with both Hilton Honors and Marriott Bonvoy upon enrollment. To top it off, you’ll earn 5x Membership Rewards points when booking flights directly with an airline.

And for travelers who value simplicity in earning and redeeming their rewards along with a reasonable annual fee, consider the Capital One Venture X card . It earns 2x Capital One miles on all purchases and comes with the lowest annual fee among the most popular premium credit cards.

Whichever card you choose, all you have to do is use it to pay for the Global Entry or TSA PreCheck application fee, and you’ll automatically be reimbursed.

How To Find Your Known Traveler Number

Hot Tip: You can find your PASSID  (also known as your Known Traveler Number) on the back of your Global Entry, NEXUS, or SENTRI card.

If you only have TSA PreCheck, log in to the Trusted Traveler Program website to access your PASSID/Known Traveler Number. If you lose your Global Entry, NEXUS, or SENTRI card, you can use the Trusted Traveler Program site to find the number.

How To Add Your Known Traveler Number to Bookings

While it might not be apparent at first, you’ll be happy to know that your TSA PreCheck or Global Entry number is, in fact, your Known Traveler Number. Simply enter your Known Traveler Number in the appropriate field when booking your flight. This can also be done later — even at the check-in desk at the airport.

The vast majority of the time, you do not need to carry your Global Entry card to access the airport’s TSA PreCheck or Global Entry lanes. That said, there have been some recent reports of travelers being asked to show their physical card. This appears to happen most at airports that allow travelers with Global Entry to preclear security, especially for flights departing from Canada. It also may happen when entering the U.S. by car via NEXUS or SENTRI lanes.

Hot Tip:  Unlike when returning from most countries, if you want to access Global Entry lanes when returning from Canada, you will need your physical Global Entry card with you.

Global Entry or TSA PreCheck: Which One Is Right for You?

As anyone who’s been through airport security knows, it can be a frustrating hassle. To expedite the screening process  at many U.S. airports, TSA PreCheck access provides a much better experience. If you are returning to the U.S. from an international destination, Global Entry can make getting through customs a breeze.

If you mainly travel within the U.S., you might think that you only need to get TSA PreCheck — this is understandable, considering the fee is $78 compared to $100 for Global Entry.

However, a Global Entry membership also provides access to TSA PreCheck. When you account for the application fee reimbursement offered by several credit cards, why wouldn’t you go ahead and get Global Entry? With the right card, the impact on your wallet is the same — neither should cost you a dime!

By getting Global Entry, you can enjoy a quicker security experience when boarding flights in the U.S. If you decide to travel abroad, you can take comfort in the fact that returning to the U.S. will be easy.

Hot Tip:  If you have additional questions, don’t miss our piece on the top Global Entry FAQs and TSA PreCheck FAQs . 

Final Thoughts

Airports are becoming busier by the year, so having access to TSA PreCheck and Global Entry is vital for quicker and smoother security screenings. With so many credit cards offering to reimburse you for the application fee, there is no excuse not to have a Known Traveler Number.

Whether you get TSA PreCheck or Global Entry, you’ll be all set for a better airport experience — just enter your PASSID/Known Traveler Number when booking your flight.

July 21, 2023 | 3 min read.

The last time you booked a flight a flight online, you may have noticed a field for entering a KTN (Known Traveler Number). While this number isn't required, having a KTN offers some benefits. If you're flying more than once a year, having a KTN could make your time in airport security faster and easier.

WHAT IS A KTN? A KTN is a 9-digit, unique number that identifies a traveler who is eligible to receive expedited screening through airport security. Those who pay for and are approved for TSA PreCheck receive a KTN. Those who pay for and are approved for Global Entry, NEXUS, or SENTRI, receive a PASSID, which is essentially the same as a KTN.

If you have a KTN, it's important to add it when booking airline travel to ensure the TSA PreCheck indicator appears on your boarding pass. If the TSA PreCheck indicator is not on your boarding pass, you'll have to go through standard security, even if you've been approved for TSA PreCheck.

BENEFITS OF HAVING A KTN TSA PreCheck offers travelers a faster and more convenient experience in U.S airports. Program participants can access special security lanes that are typically shorter than general security lines.

According to TSA , in March 2023, 89% of TSA PreCheck passengers waited in line for less than five minutes. That means travelers could potentially save hours each year.

When using TSA PreCheck lanes, you're not required to remove your shoes, belts, and light jackets while moving through the screening process. You also don't need to remove laptops or liquids from your bags before they are scanned.

HOW TO GET A KTN Enrolling in TSA PreCheck and receiving a KTN requires paying a $78 application fee and completing an in-person interview at an enrollment center. You'll be digitally fingerprinted during the interview to lessen the time needed for the required background check. Once approved for the program, your membership is good for five years before renewal is required.

Alternatively, international travelers can apply for Global Entry . This trusted traveler program grants expedited entry into the U.S. from international destinations. In addition, program participants automatically receive access to TSA PreCheck during domestic travel. The application fee for Global Entry is $100 and membership is valid for five years.

Check the benefits associated with your credit cards, as many credit card companies will reimburse cardholders for the application fee.

What Is a Known Traveler Number, and What Do You Do With One?

PhotoAlto / Getty Images

A Known Traveler Number (KTN), also called a Trusted Traveler Number, is a number issued by the US Transportation Security Administration ( TSA ), Department of Homeland Security (DHS), or Department of Defense (DoD). This number indicates that you have undergone a pre-flight background check or other screening before checking in for a flight.

Adding your Known Traveler Number to an airline reservation greatly increases your chances of being able to use the TSA's PreCheck security screening lanes at participating US airports. Your KTN also permits you to take advantage of expedited customs processing at select airports if you are a Global Entry member.

How Can I Get a Known Traveler Number?

The easiest way to get a KTN is to enroll in either the PreCheck or Global Entry program. If your application is approved, you will receive a KTN. A Global Entry KTN is linked to your passport information, while a PreCheck KTN is connected only to the personal information you supplied when you enrolled. Participating airlines may offer their frequent flyers PreCheck status. The airline will assign these travelers a KTN as part of that process. Active duty military personnel may use their DoD identification number as their KTN.

You may also apply for PreCheck or Global Entry on your own. US citizens pay $85 for a five-year PreCheck membership or $100 for a five-year Global Entry membership. (Tip: The nonrefundable fee must be paid whether or not you are approved for PreCheck or Global Entry.) If your travels frequently take you outside the US, Global Entry might be a better option for you because it not only provides you with a KTN but also gives you access to faster customs processing access at certain airports.

How Do I Use My Known Traveler Number?

If you received your KTN through the TSA's PreCheck program, you should add it to your reservation record every time you book a flight on a participating airline. If you make a flight reservation through a travel agent, give the agent your KTN. You can also add the KTN yourself if you reserve your flight online or by telephone. 

Participating airlines, as of this writing, include:

• Alaska Airlines
• All Nippon Airways
• Allegiant Air
• American Airlines
• Aruba Airlines
• Asiana Airlines
• Austrian Airlines
• Azul Airlines
• Boutique Airlines
• British Airways
• Brussels Airlines
• Cathay Pacific Airways
• China Airlines
• Condor Airlines
• Contour Aviation
• Copa Airlines
• Delta Air Lines
• Eastern Airlines
• Edelweiss Air
• Elite Airways
• Etihad Airways
• Frontier Airlines
• Hawaiian Airlines
• InterCaribbean Airways
• Japan Airlines
• JetBlue Airways
• Key Lime Air
• KLM Royal Dutch Airlines
• Miami Air International
• Norwegian Air
• PAL Express
• Philippine Airlines
• Porter Airlines
• Qatar Airways
• Scandinavian Airlines
• Seaborne Airlines
• Silver Airways
• Singapore Airlines
• Southern Airways Express
• Southwest Airlines
• Spirit Airlines
• Sun Country Airlines
• Sunwing Airlines
• Swiss International Air Lines
• TAP Air Portugal
• Turkish Airlines
• United Airlines
• Virgin Atlantic
• VivaAerobus
• World Atlantic
• Xtra Airways

If you obtained your KTN through the Global Entry program or by virtue of your status as a US Armed Forces member, you should use it whenever you make an airline reservation, regardless of which airline you fly.

Why Don't I Get PreCheck Status Every Time?

There are several reasons why you might not be able to use the PreCheck screening lane, even though you have a KTN. For example:

Sometimes the TSA does not give PreCheck status to enrolled travelers as part of its effort to randomize security screening procedures.

The data you entered when you bought your ticket might not match the data on file with the TSA, DHS, or DoD. Your first name, middle name, last name, and date of birth must match exactly.

You may have entered your KTN incorrectly when you bought your ticket.

Your KTN might not be saved in your frequent flyer profile, or you may not have logged in to your frequent flyer account before you bought your ticket online.

If you bought your ticket through a travel agent or third party website, such as Expedia, your KTN might not have been passed along to your airline. The best way to correct this problem is to call your airline and make sure your KTN has been entered into your reservation record. Do this before you check-in for your flight.

You may not have noticed that you could not enter your KTN when you purchased your ticket online. This occasionally happens with online travel websites (third party websites). 

How to Resolve Problems

Once you have a KTN, you are supposed to use it. Always look for the KTN field when you buy an airline ticket online. Contact your airline after you complete your purchase if you do not see it.

Double-check your travel documents (driver's license, government-issued photo ID and/or passport ) to be sure your full name and birth date match the information you provided to the TSA or DHS. Save your KTN in your frequent flyer account record(s). Check your frequent flyer account profiles regularly to make sure your KTN is still entered correctly. Train yourself to look for the KTN field and enter your KTN whenever you buy an airline ticket. Call your airline before your check-in date to be sure your KTN has been added to your reservation record.

When you print your airline ticket, you should see the letters "TSA PRE" in the top left corner. These letters indicate that you have been selected for PreCheck status on your flight. If you are enrolled in PreCheck but do not see "TSA PRE" on your ticket, call your airline. The reservations agent will be able to help you sort out any problems. Remember that the TSA will not always select you for PreCheck status, even if you are enrolled in the PreCheck program.

If you encounter problems at check-in or at the airport, contact the TSA as soon as possible to find out what happened. According to the Wall Street Journal , the TSA only retains PreCheck data for three days after your flight, so you will need to act quickly.

Known Traveler Number Guide: (How to Lookup, Global Entry, Pre-Check) [2023]

This comprehensive article will tell you everything you need to know about your Known Traveler Number.

I’ll cover how you can get one and the best way to do that with programs like TSA Pre-Check and Global Entry. I’ll show you how to look-up your Known Traveler Number and add it to your travel itineraries with airlines like United, Southwest, and Delta.

Finally, I’ll explain the differences between a Known Traveler Number and a Redress Number.

Table of Contents

What is a Known Traveler Number?

A Known Traveler Number, also called your “KTN,” is a 9-digit number used to link your TSA Pre-Check enrollment to your travel itinerary in order to ensure that you can receive TSA Pre-Check benefits like expedited security screening.

This is the same number used for other trusted traveler programs, such as Global Entry, NEXUS, and SENTRI . However, for these latter programs, this number is known as your “PASSID.”

Why do you want a Known Traveler Number?

With a Known Traveler Number, you can participate in TSA Pre-Check, which means you’ll be able to breeze through security at airports.

How do you get a Known Traveler Number?

You can get a Known Traveler Number by signing up, getting approved, and paying the fees for any of the following programs:

TSA Pre-Check

Global entry.

As already discussed, TSA Pre-Check will usually get you through airport security in a breeze.

You’ll usually get access to a priority security line which is often much shorter than the standard security line (though not always, unfortunately).

You’ll also be able to go through a less restrictive and invasive screening process. You often only have to pass through a traditional metal detector (as opposed to the full-body scanners) and you also get to enjoy the following benefits:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids ( 3-1-1 Rule ) can stay in bag

This program costs $78 to enroll for five years and it does not require the extensive interview process that Global Entry requires. There are multiple ways to get TSA Pre-Check for free and you can read about those here.

Global Entry would be my preferred method for obtaining a Known Traveler Number. That’s because not only will you get TSA Pre-Check, but you’ll also get expedited entry at Customs and Immigration when making your way back into the US.

This program does require you to attend an interview to be approved but the interview process is not difficult at all . If you’ve got a clean criminal history and come prepared with your documents then you should pass the background check and interview without any issues at all.

In some cases this “interview” process will only take about five minutes total.

You might get asked some very basic questions like what countries you have visited and whether or not you have traveled for business or pleasure. It’s hardly anything close to an interrogation in most cases.

The hardest part is often scheduling the interview because availability can be limited and in some cases it might take weeks (or even months) to find an open slot.

Luckily, some airports offer interviews upon arriving from international locations. So if you have some international travel coming up, this can be one of the easiest ways to get approved for Global Entry.

There are many credit cards that come with a $100 statement credit for your Global Entry application fee, so it’s very easy to get this program for free. My personal recommendations for getting a $100 statement credit for your Global Entry/TSA Pre-Check is to go with the United Explorer Card. It has great perks and a low annual fee and you can read more about it here! 

Since you’ll get both TSA Pre-Check and expedited entry back into the US, I think Global Entry is the way to go for many people.

NEXUS is a joint program between the US and Canada that will grant pre-approved, low-risk travelers expedited entry into  both  Canada and the US. Specifically, membership in the NEXUS program allows you to reduce your wait times at designated ports of entry by:

• Using dedicated processing lanes at land border crossings
• Using NEXUS kiosks when entering Canada
• Using their card in dedicated SENTRI lanes along the U.S.-Mexico border
• Using Global Entry kioks when entering the United States, and
• Calling a marine telephone reporting center to report your arrival into the United States and Canada

You may also be granted access to the Canadian Air Transport Security Authority (CATSA) Security Line at some Canadian airports to expedite airport pre-boarding security screening. (This is like a Canadian version of TSA Pre-Check.)

Just like Global Entry, NEXUS will require you to clear a background check. The difference is that this background check also is submitted to Canadian authorities, such as the  Canadian Security Intelligence Service (CSIS), Royal Canadian Mounted Police (RCMP).

One of the major draws to the NEXUS program is that the  application fee is only $50 . This is surprising since NEXUS comes with both Global Entry and TSA Pre-Check, which cost $100 and $85 respectively. For people who live near or travel between the US/Canada border, NEXUS is an especially attractive bargain.

The Secure Electronic Network for Travelers Rapid Inspection (SENTRI) is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States.

You can enter the United States by using dedicated primary lanes into the United States at Southern land border ports so this is a program you might be interested in if you’re traveling between the US and Mexico a lot.

You might be a little overwhelmed with all of the different Trusted Traveler programs and perhaps you’re not sure which program you should sign-up for.

If that’s the case you can check out this TSA tool  which can help you narrow down what program is most ideal for you based on your citizenship, number of flights, and travel destinations.

Other related travel programs

CLEAR is a privately owned service offered to passengers that allows them to bypass the lines going into airport security, whether you are going into the standard security line or the TSA Pre-Check line.

In order to use it you find the CLEAR line leading to security which should have little to no line and then you simply scan your boarding pass and biometric data and then you’re off to the races and able to skip whatever line you would have been waiting on. You don’t even have to show your ID.

CLEAR can be great for frequent flyers in busy airports but it’s not cheap at $179 per year (though cheaper promos are often available). This program does not require you to have a Known Traveler Number.

Mobile Passport

Launched in the fall of 2014, Mobile Passport Control is an app, developed by Airside Mobile and Airports Council International-North America in partnerships with CBP, that you can download to use in order to expedite your entry into the US. It’s available in the  Apple App Store  and  Google Play .

It’s free to use and can be just about as good as Global Entry at some airports, though I’d still take Global Entry over Mobile Passport.

That’s because Global Entry gets you Pre-Check and also allows you to get through customs AND immigration while Mobile Passport often only get your priority access through immigration. This program also does not require you to have a Known Traveler Number.

Adding a Known Traveler Number

Once you have your Known Traveler Number, you’re going to need to add that number to your travel profiles for the various airlines so that your Known Traveler Number will automatically show up in your itineraries.

However, you should note that your Known Traveler Number will NOT automatically show up in all of your travel  itineraries.

Many people assume that once they add their Known Traveler Number to their profile, it will always show up but that’s not the case. So you always need to double check that your KTN was added.

Below, you can see how to add your Known Traveler Number to some of the major airlines. For whatever reason, it is not always the easiest thing to do since you often have to click around a lot.

Usually you can find where to input it if you just look for your profile and a button allowing you to edit your profile, but the steps below should help you locate this.

American Airlines

Sign in to your American Airlines account and then click on your name at the top of the page. Then click on “your account.” Next, click on “edit account” and then click on “Information and password.” Scroll down and then under “Secure traveler,” you will see where to input your Known Traveler Number.

Sign in and click on “My Account” and then scroll to “My Preferences” to change your personal details within your profile information.

Sign in and click on Profile and Preferences and then click on “Travel identification documents” and then you’ll see the area to enter it in below.

Go to the Delta website and log-in and then proceed to My Delta -> My Profile -> Basic Info. You’ll then see a field where you can input your Known Traveler Number.

First, sign in to your JetBlue account. Click on the arrow in the upper right corner by your name and then click on “Edit profile.” Scroll down and you will see where to input your information.

Hawaiian Airlines

First, sign in to your Hawaiian Airlines account. Go to My Account and under that click on “Profile & Settings.” Click on the travel tab and you will see where to input your information.

Travel portals and OTAs

Most online travel agencies (like Expedia) will allow you to enter in your Known Traveler Number into your profile which should populate into your itinerary when you make a booking.

But since you’re dealing with a third party, you should always verify that your number was properly included in your booking.

Add Known Traveler Number after booking?

If you add your Known Traveler Number to your profile after you make a flight reservation, there’s a good chance that your flight itinerary is not linked to your Known Traveler Number and you won’t get TSA Pre-Check. 

In that case, you should be able to call up the airline and request for them to input your number into your itinerary.

You could also just wait until you arrive at the check-in desk for baggage and request for your Known Traveler Number to be added to your boarding pass.

Also, sometimes you’ll have to re-add your Known Traveler Number to specific itineraries. It’s not always clear why this happens but sometimes you’ll just have to do it.

If you ever are given a boarding pass without TSA Pre-Check on it and you know you have a TSA Pre-Check membership, simply approach an agent at the check-in desk and tell them you would like to add your Known Traveler Number.

It’s usually no problem for them to do this and they can re-issue you a boarding pass in a couple of seconds that has TSA Pre-Check.

For the reasons above, I highly recommend that you keep your Known Traveler Number somewhere easily retrievable like in your smart phone in a folder or app that you won’t forget about and can quickly pull up.

Where can I look up and find my Known Traveler Number?

If you are a member of the TSA Pre-Check Application Program you can, look up your KTN online .

If you are a member of another trusted traveler program, such as Global Entry, NEXUS, or SENTRI,  log on to the Trusted Traveler Program website  to obtain your PASSID, which once again is the same as your KTN.

You’ll find it right under “Program Memberships.”

You can also check the back of your trusted traveler cards for your PASSID. Note that TSA does not issue an ID card like Global Entry, NEXUS, and SENTRI do.

Related: Can You Get Through TSA and Fly with No ID?

What is a redress number?

You might also be wondering about a redress number since that field often shows up near where you input your Known Traveler Number.

A redress number is the record identifier for people who apply for redress through the DHS Travel Redress Inquiry Program (DHS TRIP) .

“DHS TRIP is for travelers who have been repeatedly identified for additional screening and who want to file an inquiry to have erroneous information corrected in DHS systems.”

For example, someone might share the same name as another person on a no-fly list and that might bring up a red flag every single time this unfortunate traveler attempts to board a plane.

The redress number will help those people avoid additional searches, pat downs, and questioning in the future.

So in case you were wondering a redress number really has nothing to do with your Known Traveler Number.

Known Traveler Number for Military members

If you are a member of the military, you can utilize TSA Pre-Check for free.

Members of the U.S. Armed Forces can get expedited screening including those serving in the U.S. Coast Guard, Reserves, and National Guard.

This can be done by using the official Department of Defense (DoD) identification number when making flight reservations. Your 10-digit DoD ID number is located on the back of your Combined Access Card ID and it is not the same as your SSN. Read more about how to utilize this benefit here.

TSA Pre-Check vs Global Entry

Now that you’re aware of all of the benefits you might be wondering whether or not you should choose TSA Pre-Check or Global Entry.

The answer to this question depends a lot on your personal preferences.

If you are only going to be traveling within the US then your need for Global Entry will be nearly zero.

In that case, getting TSA Pre-Check should be just fine. The only drawback to that is that if an unexpected trip comes up you’ll lose out on the benefit you could have had with Global Entry.

On the other hand, if you’re going to be traveling internationally then you might want to think about Global Entry since it will save you a lot of time getting back into the country.

The two drawbacks to Global Entry are that it requires you to attend an interview and that the background check can be tough to clear if you have anything on your record like a DWI, DUI, etc.

Known Traveler Number FAQ

The easiest way would be to get approved for TSA Pre-Check .

No, you do not need a Known Traveler Number for CLEAR?

At the time of booking, you will typically see a field where you can enter your Known Traveler Number. In addition, you can add your Known Traveler Number to your frequent flyer profile. If you are at the airport, you can also ask an agent to add your Known Traveler Number to your boarding pass.

There is no practical difference and these are essentially the same.

As you can see, getting a Known Traveler Number can be very easy and can even be done for free with the right credit card.

I recommend going with a program like Global Entry to get your PASSID/Known Traveler Number and using a credit card with a $100 credit for Global Entry.

If you always keep your Known Traveler Number with you at all times you’ll be able to add it to your boarding pass when needed and there shouldn’t be any major issues.

How to Find Your KTN (Plus How to Enroll in or Renew PreCheck)

Finding Your KTN

Enrolling in a trusted traveler program, renewing your tsa precheck authorization, expert q&a.

TSA PreCheck makes it easy for you to breeze through airport security without having to take off your shoes, belt, or jacket. But to access those PreCheck lanes, you need to enroll in the service and provide your PreCheck number—called a Known Traveler Number (KTN)—to the airline when you book your flight. If you've forgotten your KTN, the easiest way to find it is to check the TSA Enrollment website.

Things You Should Know

• Look for your KTN on official sources, such as your approval letter, or the TSA Enrollment website , if you're a US citizen.
• Use the PASSID on your membership card as your KTN if you're enrolled in the Global Entry, NEXUS, or SENTRI programs.
• Enroll in Precheck programs online to get a KTN. Schedule an in-person appointment, supply the required documents, and pay the application fee for approval.
• Check your TSA Precheck status and fill out the renewal application online within 6 months before it expires so it's continuously active.

• Your PASSID is a 9-digit number that usually starts with 15, 98, or 99.
• If you previously enrolled in TSA PreCheck directly, but then enrolled in Global Entry, NEXUS, or SENTRI later, use the PASSID associated with the later program as your KTN—it supersedes your previous enrollment.

• This receipt isn't the same as your approval letter. Your approval letter was mailed to you after your Enrollment Center appointment and has your KTN on it. Your UE ID and your KTN are two different things.

• The TSA also has an online form , but you'll probably get a quicker resolution by calling.

• TSA PreCheck : access to PreCheck lanes for airport departures; US citizens and lawful permanent residents are eligible; $78 for 5 years
• Global Entry : entry to the US from international destinations by air, land, or sea; access to PreCheck lanes for airport departures; US citizens, lawful permanent residents, and select foreign nationals are eligible; $100 for 5 years
• NEXUS : entry to the US from Canada by air, land, or sea; includes access to PreCheck lanes for airport departures for US citizens and lawful permanent residents as well as Canadian citizens; US citizens and permanent residents, Canadian citizens and permanent residents, and Mexican nationals are eligible; $50 for 5 years
• SENTRI : entry to the US from Canada and Mexico by air or land; includes access to PreCheck lanes for airport departures for US citizens and lawful permanent residents; US citizens and permanent residents, as well as all foreign nationals, are eligible; $122.25 for 5 years

• If you'd rather apply in person, enter your ZIP code in the TSA Enrollment Center locator to find the nearest Enrollment Center.

• If you need to reschedule your appointment, you can do that from the TSA Enrollment website as well. The Enrollment Centers do take walk-ins, although you may have to wait a while, especially during peak hours.

• List A : unexpired passport book or card, permanent resident card, unexpired US enhanced driver's license or enhanced state-issued ID
• List B : unexpired driver's license or state ID, unexpired US military ID, expired passport within 12 months of expiration, US birth certificate, US certificate of naturalization

• Many credit cards help offset or even cover the cost of TSA PreCheck membership as a benefit to customers—especially cards with travel or airline miles incentives. Contact your credit card company to see if this is a perk for you.

TSA PreCheck

Breeze through security.

TSA PreCheck ® is an expedited security program allowing eligible travelers to speed up their screening process at participating U.S. airports and for most international trips. To participate, you must apply and get approval from the Transportation Security Administration (TSA).

If you have TSA PreCheck, you’ll go through a dedicated screening lane at the airport where you may not need to remove your shoes, jacket, belt or laptop from your bag.

TSA PreCheck is also available if you’re enrolled in a Customs and Border Protection (CBP) Trusted Traveler program, including Global Entry, SENTRI, or NEXUS.

Citi® / AAdvantage® Executive Mastercard®

Citi ® / AAdvantage ® Executive Mastercard ® card members receive an application fee credit for Global Entry or TSA PreCheck, up to $100 every 5 years. To receive reimbursement, you must charge the application fee to your Citi ® / AAdvantage ® Executive Mastercard ® .

Travel with TSA PreCheck

If you apply directly through TSA, you’ll receive a Known Traveler Number (KTN). If you’re registered with a CBP program, you’ll receive a 9-digit PASS ID, which is the same number for all CBP programs.

Update your KTN or PASS ID in your AAdvantage ® account before you travel so your information is saved for every trip. If you’re not an AAdvantage ® member, you must add your KTN or PASS ID to each reservation when you book.

If you can’t find your KTN or PASS ID, you can get them online.

Redress number vs. known traveler number: understanding the difference.

In the world of customs and border protection, you may find some of the terminology unclear. For example, you may have heard of redress numbers vs. Known Traveler Numbers (KTN) in the context of airport security. But what do those terms mean and what are the differences?

What is a redress number?

Much like other travel identification numbers assigned by the government, a redress number is designed to expedite the border security process.

Redress numbers are issued by the Department of Homeland Security to individuals who have previously experienced difficulties during screening at transportation hubs such as airports. These difficulties may include watch list issues, screening problems at ports of entry and situations where a traveler believes they have been unfairly or incorrectly delayed, identified for additional screening or denied boarding.

If you do think you're eligible for a redress number, you can apply online through the Department of Homeland Security's website. After submitting your application, it will become subject to approval, which can take up to 50 business days.

Upon approval, you will receive your redress number, which you'll be able to use when traveling. This should help you avoid difficulties at security screenings going forward.

Note that if your security issues relate to a criminal record or an instance of excessive intoxication, you will likely not be eligible for a redress number.

What is a Known Traveler Number?

Separate from a redress number, a Known Traveler Number is issued to people who apply to and are approved for TSA PreCheck ® , the program that allows approved travelers to access expedited security lines for domestic travel in the United States.

Additionally, while the terminology is slightly different, a similar identification number is issued to those who apply to and are approved for Global Entry, NEXUS and SENTRI, programs that allow for expedited access into the United States via air, land or sea. In this case, you'll be issued a PASSID number, which is entered in the same place as the Known Traveler Number when booking air travel.

Like a redress number, a Known Traveler Number is also issued by the Department of Homeland Security, and recipients must go through an application and screening process to be approved. This then grants entry to the TSA PreCheck line, which allows travelers to go through airport security without removing liquids, laptops, shoes, belts or light outerwear.

Redress number vs. KTN: Differences and benefits

The main differences between a redress number and a Known Traveler Number are the circumstances in which it's issued and used.

A redress number relieves part of the stress of traveling by making it less likely you will be targeted for additional screening, or delayed or denied boarding or entry. Ultimately, the goal of a redress number is to create a smoother traveling experience for those who have had difficulties with security in the past. It works to correct the potential misidentification of travelers as high risk, thus complicating their experience through security.

By contrast, a Known Traveler Number allows travelers to access specially approved security lines and screening processes designed to expedite their wait time. Additionally, unless you are an active member of the military, you pay for this perk. TSA PreCheck costs $78 as of April 2023 for a five-year membership. This fee is subject to change, so be sure to check the TSA PreCheck website for the most up-to-date cost. A redress number, on the other hand, is free.

If comparing a redress number vs. a Known Traveler Number, you'll find the “why" behind the two numbers the biggest difference. Redress numbers are intended to correct misidentifications that may lead to security issues for certain travelers, while a Known Traveler Number is a travel perk you can pay for. Ultimately, their goal is the same — to help make your travel a little bit smoother.

What Does Known Traveler Number Mean

Published: December 16, 2023

Modified: December 28, 2023

by Lucie Halstead

Introduction

If you are a frequent traveler, you know that navigating through airport security can sometimes be a time-consuming and frustrating process. The long lines, removing shoes and belts, and unpacking laptops and liquids can take a toll on even the most patient of travelers. However, there is a solution that can help streamline your airport experience and make your travels more efficient: the Known Traveler Number.

The Known Traveler Number, also known as a KTN, is a unique identification number that is issued to travelers who have been pre-screened and deemed low-risk by the Transportation Security Administration (TSA). This number is associated with your personal information and allows you to access expedited screening lanes at participating airports.

In this article, we will delve deeper into the world of the Known Traveler Number, exploring its definition, eligibility requirements, benefits, and how to apply for one. We will also discuss the differences between the Known Traveler Number and other similar programs such as TSA Pre✓ and Global Entry. So, let’s get started!

Definition of Known Traveler Number

The Known Traveler Number (KTN) is a unique identification number assigned to travelers who have undergone a thorough pre-screening process conducted by the Transportation Security Administration (TSA) in the United States. This number serves as a way to efficiently identify and differentiate low-risk travelers from the general public, allowing them to enjoy expedited security screening at airports.

When you apply for a Known Traveler Number, you are essentially providing the TSA with your personal information, such as your full name, date of birth, and gender. The TSA then uses this information to conduct a background check, ensuring that you do not pose a threat to aviation security. If you pass the screening process, you will be issued a unique Known Traveler Number that is valid for five years.

It’s important to note that the Known Traveler Number is not a physical card or document. Instead, it is a virtual identification number linked to your name and associated with your airline reservations. This means that once you have been approved for a Known Traveler Number, you will need to provide that number each time you book a flight, ensuring that you receive the benefits of expedited screening.

The Known Traveler Number is often confused with other travel programs, such as TSA Pre✓ and Global Entry. While these programs offer similar benefits, they are not interchangeable, and each has its own eligibility requirements and application processes. In the next sections, we will delve deeper into the eligibility criteria and how to apply for a Known Traveler Number.

Eligibility for Known Traveler Number

To be eligible for a Known Traveler Number (KTN), you must meet certain criteria set by the Transportation Security Administration (TSA). While the requirements are not overly restrictive, it is important to understand the qualifications before applying.

First and foremost, you must be a citizen or lawful permanent resident of the United States. Additionally, certain non-U.S. citizens may also be eligible for a Known Traveler Number if they meet specific criteria, such as Canadian citizens who are members of NEXUS or Mexican citizens who are members of SENTRI.

Next, you must undergo a comprehensive background check conducted by the TSA. This screening process involves verifying your identity, reviewing any criminal history, and cross-referencing numerous databases. The purpose of this screening is to determine if you are a low-risk traveler and if your participation in the program would pose a threat to aviation security.

In order to qualify for a Known Traveler Number, you must have a clean criminal record and not be on any government watchlists. It is important to disclose any relevant criminal history or legal issues during the application process, as failing to do so can result in disqualification.

Another factor to consider is your travel history and patterns. The TSA looks at your frequency of travel and whether you have a history of compliance with security protocols. While there is no minimum requirement for the number of flights you must have taken, being a frequent traveler can increase your chances of being accepted into the program.

It’s also worth noting that children under the age of 18 who are traveling with a parent or guardian with a Known Traveler Number can benefit from expedited screening as well. However, they must be included in the same reservation as the eligible adult and follow the necessary procedures.

Overall, the eligibility requirements for a Known Traveler Number are relatively straightforward. As long as you are a U.S. citizen or lawful permanent resident, pass the background check, and have a clean criminal record, you are likely to meet the criteria. Once you have determined your eligibility, the next step is to apply for a Known Traveler Number, which we will explore in the next section.

Benefits of Known Traveler Number

Obtaining a Known Traveler Number (KTN) comes with a range of benefits that can greatly enhance your travel experience. Let’s explore some of the advantages of having a Known Traveler Number:

• Expedited Airport Security: One of the primary benefits of a Known Traveler Number is access to expedited security screening through the TSA Pre✓ program. Instead of waiting in long lines and removing your shoes, belts, and laptops, you can use dedicated lanes where you can keep your shoes on, leave your laptop in its bag, and breeze through security with ease. This can save you valuable time, especially during peak travel seasons.
• Enhanced Convenience: With a Known Traveler Number, you can enjoy a more convenient and streamlined travel experience. As a trusted traveler, you won’t need to undergo the same level of scrutiny as the general public. This means that you can spend less time waiting and more time enjoying your journey.
• Reduced Stress: By bypassing the regular security lines, you can reduce the stress and anxiety often associated with airport travel. You can avoid the hassle of unpacking and repacking your belongings, making the overall experience more pleasant and relaxing.
• More Predictable Travel: With a Known Traveler Number, you can have a higher level of confidence in predicting the time it will take to clear security. Expedited screening allows you to factor in the reduced wait times, ensuring that you can plan your schedule more efficiently.
• Access to Global Entry Kiosks: If you are an international traveler, having a Known Traveler Number makes you eligible for Global Entry, which provides expedited customs and immigration clearance when returning to the United States. This means a faster and smoother entry process, avoiding long immigration queues and speeding up your journey home.
• Transferable Benefits: The benefits of a Known Traveler Number are not limited to just you. If you are traveling with children under the age of 12, they can accompany you through the TSA Pre✓ lanes as well, even if they do not have their own Known Traveler Numbers. This can make family travel more convenient and efficient.

Overall, having a Known Traveler Number can significantly improve your travel experience by providing expedited security clearance, enhanced convenience, reduced stress, and predictability. Make sure to take advantage of these benefits and enjoy a more seamless journey through the airport!

How to Apply for a Known Traveler Number

Applying for a Known Traveler Number (KTN) is a straightforward process that can be completed online. Follow these steps to apply for your own Known Traveler Number:

• Step 1: Determine Your Eligibility – Before applying, make sure you meet the eligibility criteria for a Known Traveler Number. You must be a U.S. citizen or lawful permanent resident and pass a comprehensive background check conducted by the Transportation Security Administration (TSA).
• Step 2: Create a Trusted Traveler Program Account – Visit the TSA website and create a Trusted Traveler Program account. This account will serve as your portal for managing your application and accessing your Known Traveler Number.
• Step 3: Complete the Application – Fill out the online application form accurately and ensure that all information provided is correct. This includes personal details such as your full name, date of birth, and contact information.
• Step 4: Pay the Application Fee – There is a non-refundable application fee associated with the Known Traveler Number application process. At the time of writing, the fee is $85. This fee covers a five-year enrollment period.
• Step 5: Schedule an Interview (if required) – In some cases, applicants may be required to attend an in-person interview with a TSA officer. The TSA will notify you if an interview is necessary and provide instructions on how to schedule it.
• Step 6: Wait for Approval – After submitting your application and completing any necessary interviews, the TSA will review your information and conduct the background check. This process typically takes a few weeks. Once approved, you will receive your Known Traveler Number.
• Step 7: Add Your Known Traveler Number to Your Travel Reservations – Once you have received your Known Traveler Number, make sure to add it to your airline reservations for every trip. This will ensure that you are eligible for expedited security screening. You can usually do this during the booking process or by editing your existing reservations.

It’s important to note that the application and approval process may vary for non-U.S. citizens and members of other trusted traveler programs, such as NEXUS and SENTRI. Be sure to check the specific instructions provided on the TSA website to ensure you follow the correct application procedures.

By following these steps and completing the application process, you will be on your way to enjoying the benefits of a Known Traveler Number and experiencing a more efficient and hassle-free airport journey.

Known Traveler Number vs. TSA Pre✓

The Known Traveler Number (KTN) and TSA Pre✓ are two programs that offer expedited security screening at airports, but they differ in how travelers qualify and access the benefits. Let’s examine the differences between these two programs:

Known Traveler Number:

The Known Traveler Number is a unique identification number issued to travelers who have undergone a thorough background check conducted by the Transportation Security Administration (TSA). This number is valid for five years and is associated with your personal information, allowing you to access expedited screening lanes at participating airports.

With a Known Traveler Number, you can enjoy a range of benefits, including keeping your shoes and belt on, leaving your laptop in its bag, and passing through dedicated security lanes. This applies not only to domestic flights but also to select international flights departing from U.S. airports.

TSA Pre✓:

TSA Pre✓ (pronounced “TSA PreCheck”) is a program that offers expedited security screening to eligible travelers. Unlike the Known Traveler Number, TSA Pre✓ is available exclusively to U.S. citizens and lawful permanent residents. Canadian citizens who are members of NEXUS and Mexican citizens who are members of SENTRI can also qualify for TSA Pre✓.

To access TSA Pre✓ benefits, you must apply separately for the program and undergo a background check. If approved, you will receive a Known Traveler Number that begins with the letters “TT” for TSA Pre✓. Alternatively, individuals who participate in other trusted traveler programs, such as Global Entry, automatically receive TSA Pre✓ benefits.

With TSA Pre✓, you can enjoy expedited security screening, similar to the Known Traveler Number, including keeping your shoes on, leaving your laptop in its bag, and going through dedicated screening lanes. However, TSA Pre✓ is only available for domestic flights within the United States at participating airports.

Key Differences:

The main differences between the Known Traveler Number and TSA Pre✓ are:

• Eligibility: The Known Traveler Number is available to U.S. citizens, lawful permanent residents, and certain non-U.S. citizens, while TSA Pre✓ is only available to a more limited group of individuals, primarily U.S. citizens and lawful permanent residents.
• Authorization Process: To obtain a Known Traveler Number, you undergo a background check and receive approval directly from the TSA. For TSA Pre✓, you must apply specifically for the program and undergo a separate background check.
• Availability: The Known Traveler Number provides expedited screening for select international flights as well as domestic flights, while TSA Pre✓ benefits are limited to domestic flights within the United States.

In summary, the Known Traveler Number and TSA Pre✓ offer similar benefits of expedited security screening at airports, but they differ in eligibility, application process, and availability. Both programs can significantly enhance your travel experience by reducing wait times and providing a more seamless journey through security checkpoints.

Known Traveler Number vs. Global Entry

The Known Traveler Number (KTN) and Global Entry are both programs that offer expedited travel benefits, but they serve different purposes and cater to different needs. Let’s explore the differences between these two programs:

The Known Traveler Number is a unique identification number issued by the Transportation Security Administration (TSA) to low-risk travelers who have undergone a thorough background check. The main purpose of the Known Traveler Number is to provide expedited security screening at airports. With a Known Traveler Number, you can enjoy benefits such as keeping your shoes and belt on, leaving your laptop in its bag, and passing through dedicated security lanes at participating airports.

The Known Traveler Number is valid for five years and is associated with your personal information. It is primarily used for domestic flights within the United States, but it can also offer expedited screening for select international flights departing from U.S. airports.

Global Entry:

Global Entry is a program offered by U.S. Customs and Border Protection (CBP) that provides expedited clearance for pre-approved, low-risk travelers entering the United States. Unlike the Known Traveler Number, Global Entry is geared towards international travelers and focuses on facilitating the customs and immigration process when entering the United States.

When approved for Global Entry, travelers receive a Known Traveler Number as part of their membership. This Known Traveler Number grants them access to expedited security screening through TSA Pre✓ lanes at domestic airports, in addition to the benefits of Global Entry. Global Entry members can use automated kiosks to scan their passports and fingerprints, allowing for a faster and more seamless entry process at participating airports.

The main differences between the Known Traveler Number and Global Entry are:

• Purpose: The Known Traveler Number focuses on expedited security screening at airports, while Global Entry is primarily aimed at expediting the customs and immigration process when entering the United States.
• Application Process: The Known Traveler Number is obtained by applying directly to the TSA, while Global Entry requires a separate application through U.S. Customs and Border Protection. Global Entry applicants must also undergo an in-person interview as part of the vetting process.
• International Travel Benefits: While the Known Traveler Number can provide expedited screening for select international flights, Global Entry offers additional benefits for international travelers, such as expedited customs and immigration clearance through automated kiosks.

In summary, the Known Traveler Number provides expedited security screening at airports primarily for domestic flights, while Global Entry offers expedited clearance for international travelers entering the United States. While both programs can enhance your travel experience, their focus and benefits cater to different aspects of the travel process.

Frequently Asked Questions (FAQs)

The Known Traveler Number (KTN) is a valuable tool that can greatly enhance the travel experience for frequent flyers. By providing expedited security screening at airports, it offers a range of benefits, including saved time, reduced stress, and enhanced convenience.

In this article, we explored the definition of the Known Traveler Number, its eligibility criteria, and the process of applying for one. We also compared the Known Traveler Number to other programs such as TSA Pre✓ and Global Entry, explaining their similarities and differences.

With a Known Traveler Number, travelers can enjoy the convenience of keeping their shoes and belts on, leaving their laptops in bags, and bypassing long lines at security checkpoints. Not only does this save time, but it also adds predictability to the travel experience and reduces the hassle associated with airport security procedures.

However, it’s important to note that the Known Traveler Number is just one piece of the puzzle. Travelers should still adhere to airport rules and regulations, arrive at the airport with sufficient time, and follow the instructions of security personnel. The Known Traveler Number is not a guarantee of expedited screening in every situation, as it may depend on factors such as airport capacity and security policies.

If you are a frequent traveler or plan to travel extensively, obtaining a Known Traveler Number can be a worthwhile investment. It provides numerous benefits and can significantly improve your overall travel experience.

Remember to always stay informed about the latest updates and changes to the Known Traveler Number program by visiting the official TSA website or contacting customer support for any inquiries.

So, take the first step, apply for a Known Traveler Number, and enjoy the convenience and efficiency it offers. Happy travels!

What is a redress number for flying?

Do i need a redress number, how do i apply for a redress number, how do i use a redress number, redress numbers for tsa recapped.

Whenever you travel by air within, to or from the U.S., you’re electronically screened using the Transportation Security Administration Secure Flight screening program. While this system is transparent for most passengers, it occasionally misidentifies passengers as high risk.

If you've frequently been stopped for additional security during travel or have been denied travel for security reasons, you may consider applying for a redress number to avoid this in the future.

The redress number meaning is a numeric identifier given to individuals who were falsely identified as posing threats to transportation security or public safety when flying. It aims to streamline TSA checkpoints for these travelers.

Here's how redress numbers for travel work and if applying for one is a smart move for you.

The short answer is a redress number is an identifier that allows TSA to match you with the results of your redress case. A redress number is used by the TSA’s Secure Flight program to simplify the watchlist matching process and can prevent future false matches of people who have been misidentified as matching a watchlist in the past.

A redress number is different from a Known Traveler Number , which identifies your membership in Trusted Traveler programs like TSA PreCheck and Global Entry .

Most travelers won't have a redress number. Only people who have applied for the Department of Homeland Security’s Traveler Redress Inquiry Program, or TRIP, will have one.

If you don't have a redress number and an airline or travel site requests a redress number as part of a booking process, you'll simply leave that field blank.

If you've been denied travel or delayed during travel for additional security screening, or if you've had trouble getting through checkpoints at U.S. borders, DHS TRIP may provide relief from security-related travel woes.

Specifically, TSA suggests that you apply for a redress number if you've had issues like being unable to print a boarding pass, being denied or delayed boarding of a plane, being denied or delayed entry into or exit from the U.S. at a border checkpoint, or are frequently referred for additional screening at an airport.

Here is the list of issues that DHS says TRIP can help resolve:

You were unable to print a boarding pass from an airline ticketing kiosk or from the Internet.

You were delayed or denied boarding an aircraft.

The airline ticket agent informed you that the federal government was not authorizing you to travel.

You are repeatedly referred for secondary screening when clearing a U.S. Customs and Border Protection checkpoint or were denied entry into the U.S.

You were told by CBP at a U.S. port of entry that your fingerprints need to be corrected.

You wish to amend a traveler record because of an overstay as a result of not submitting the required I-94 when exiting the U.S.

You believe you were incorrectly denied ESTA authorization.

If you frequently experience issues like these when traveling, you might want to apply for DHS TRIP.

Note that TRIP is meant to resolve security-related issues like watchlist mismatches. It isn't intended to resolve customer-service complaints, address issues related to discrimination, help you find lost or damaged items or provide assistance during security screening.

Further, having a redress number doesn't guarantee that you'll never be selected for additional screening, but it makes additional screening less likely if you've been previously falsely matched to a watchlist.

» Learn more: TSA PreCheck or Global Entry — which is right for you?

You can apply for a redress number through the Traveler Redress Inquiry Program portal if you believe that you're being incorrectly stopped or screened when flying.

During the application process, you'll be asked a series of screening questions to determine if obtaining a redress number may help solve your travel issues.

To apply, you'll be required to submit ID documents proving your identity. U.S. citizens should provide a copy of the biographical page of an unexpired U.S. passport or, for those without one, a copy of an unexpired government-issued photo identification.

Minors may provide a copy of a birth certificate. Get more advice on how to successfully navigate TSA PreCheck with a family .

Non-U.S. citizens must provide a copy of the biographical page of an unexpired passport and/or copies of one of several U.S. government-issued identification documents. Acceptable identification documents include:

Passport card.

Driver's license.

Birth certificate (for people younger than 18.)

Military identification card.

Government identification card.

Certificate of citizenship.

Naturalization certificate.

Immigrant/non-immigrant visa.

Alien registration.

Petition or claim receipt.

I-94 admission form.

SENTRI card .

NEXUS card .

Border crossing card.

SEVIS card.

After the DHS receives and processes your application, it will send you a resolution letter detailing the outcome of your application. If you feel that your redress request was resolved incorrectly, you should follow the instructions in your resolution letter.

Making sure your redress number is attached to your air travel reservations will give you the greatest chance of avoiding security hassles when flying or crossing U.S. borders.

You can attach your redress number to a travel reservation during booking, you can add it to your frequent flyer profile or you can ask an airport agent to add your redress number to your reservation at check-in.

Enter your redress number during booking

Enter your redress number during the booking process when using most online travel agencies, airline websites or travel agents.

For example, when booking a flight on Expedia , you can enter your redress number after you provide your name, gender and date of birth. Look for the option to expand the “Frequent flyer, redress and more” section of this page.

Other online travel agencies and airline websites will typically have a similar option during their booking process.

Enter your redress number in your frequent flyer profile

If you belong to a frequent flyer program , you can add your redress number to your loyalty member profile. For many travelers, this is the most convenient way to ensure that your redress number is applied automatically to all their reservations. The process will vary by airline, but this can typically be done online, similarly to how you would add a known traveler number.

If you are a Delta Air Lines SkyMiles member, for example, you can add your redress number to the Secure Flight Info section of your profile. On Delta.com, your Secure Flight Information can be found under the Passenger Details section of your profile.

Similarly, Southwest Airlines members can enter their redress number under the “Travel related info” panel in the personal information section of their profile.

Exactly how to enter your information varies by airline, but the field to enter your redress number can typically be found in the same place where you enter your known traveler information.

Give your redress number to an airport agent

There may be times when you are unable to add your redress number to your reservation until check-in.

For example, if you book travel as part of a group tour package and your tour provider doesn’t provide your airline confirmation number, or if you booked through an online travel agency and forgot to add your redress number to your reservation, you may show up at the airport without your redress number attached to your reservation.

Most airport ticketing agents should be able to add your redress number to your reservation upon check-in.

While a redress number isn't required for travel and not everyone will need one, if you’ve experienced security-related issues while flying, applying for a redress number may be right for you. By adding it to your travel bookings or frequent flyer accounts, you can help TSA identify you to save time and stress.

Why is 4/20 the unofficial weed day? The history behind April 20 and marijuana

The favorite day of stoners across the globe is upon us: April 20 or 4/20 , also known as weed day, is this Saturday.

Coincidentally falling on the same weekend as National Cold Brew Day and National Record Store Day, Saturday is shaping up to be something of a paradise for weed, coffee and music fans alike.

But how did an otherwise random day in April somehow become the mecca of marijuana enjoyment? Many theories have swirled over the years. While more exciting ones harken the holiday back to police busts or hidden messages in classic songs, the widely accepted origin is a little more reminiscent of a classic high school experience.

How did 4/20 become the official unofficial weed holiday? Here's what we know.

What does 420 mean?

420 refers to the day 4/20, or April 20. The date has come to be known as the official stoner holiday on which marijuana smokers celebrate their love of bud.

The number 420 itself has also come to be associated with marijuana and smoking and is often used as a colloquial term for the flower and the act of consuming it.

Smokers see 4/20 not only as a day to kick back and celebrate their love of the stuff, but also to push for broader legalization and decriminalization of marijuana federally in the U.S. and beyond.

Why is 420 associated with weed?

You may have heard some of the most popular rumors that have circled the cultural zeitgeist over the years: that 420 is the code police used to describe marijuana smoking; 420 is the number of active chemicals in weed that get you high; April 20 was Bob Marley's birthday (it wasn't); that it's a reference to Bob Dylan’s song “Rainy Day Women #12 & 35” (12 times 35 equals 420).

In reality, it's much simpler and perhaps less exciting than any of that.

While no one can say for certain, one widely accepted origin traces back to a group of teenagers hanging out after school.

In the early '70s, five students at San Rafael High School in Marin County, California would meet outside of the school after extracurricular activities had ended for the day. The group, eventually called the "Waldos," simply for the fact they met by a wall to do their thing, made their official meeting time 4:20 p.m. and eventually started using 420 as code for smoking.

One of the Waldo members, Dave Reddix, later got work as a roadie for the Grateful Dead, and the band helped to popularize the term, he told Time. Specifically, a flyer distributed by a group of Oakland Deadheads in December 1990 inviting people to smoke on April 20 at 4:20 p.m. did the trick.

A reporter at High Times magazine got hold of the flier and printed it in 1991, bringing it to the attention of cannabis fans across state lines. The magazine continued to use the term in future publications, solidifying its place in popular vernacular.

Steve Bloom, the "High Times" reporter who originally received the flyer, later credited the Waldos for originating the term, saying in a 2013 blog , "...they wanted people all over the world to get together on one day each year and collectively smoke pot at the same time. They birthed the idea of a stoner holiday, which April 20 has become."

Where is weed legal?

Looking forward to partaking this 4/20? Make sure you know the laws in your area before you do.

The legalization of marijuana has been a long state-by-state process, and various levels of use from none to medical to recreational are allowed in jurisdictions across the U.S. At least 25 have fully legalized recreational use, and more are either in the process or have future voting on the books.
