1. Understanding Your Known Traveler Number (KTN)
Your Known Traveler Number (KTN) is a unique identifier provided as part of trusted traveler programs, designed to speed up security screenings at airports. According to the Transportation Security Administration (TSA), using your KTN allows you to access expedited screening lanes, making your travel experience more efficient.
1.1. What is a Known Traveler Number (KTN)?
A Known Traveler Number (KTN) is assigned to individuals who have been approved for trusted traveler programs, like TSA PreCheck or Global Entry, enhancing travel convenience. According to the U.S. Customs and Border Protection (CBP), a KTN helps TSA identify you as a low-risk traveler. This number ensures you can use expedited security lanes at airports across the United States.
1.2. What Are the Benefits of Having a KTN?
Having a KTN provides numerous benefits that enhance the overall travel experience.
Expedited Security Screening: A KTN grants access to TSA PreCheck lanes, which typically have shorter wait times and require less stringent screening procedures. According to the TSA, travelers with TSA PreCheck spend an average of 5 minutes or less in security lines.
Reduced Screening Requirements: Travelers with a KTN often don’t need to remove shoes, belts, or light jackets when passing through security, streamlining the screening process.
Increased Convenience: The predictability and speed of TSA PreCheck can reduce stress and uncertainty associated with airport security, making travel more enjoyable.
Family Benefits: In many cases, children aged 12 and under can join parents or guardians in the TSA PreCheck lanes without needing their own KTN, simplifying family travel.
Global Entry Benefits: If your KTN is from Global Entry, you also get expedited entry into the United States when returning from international travel, further enhancing your travel efficiency.
1.3. What Programs Provide a KTN?
Several trusted traveler programs provide a KTN, each designed to cater to different travel needs.
TSA PreCheck: This program allows U.S. citizens, U.S. nationals, and lawful permanent residents to undergo expedited security screening at participating U.S. airports.
Global Entry: This program is ideal for frequent international travelers, providing expedited U.S. customs and immigration clearance upon arrival. Global Entry members also receive TSA PreCheck benefits.
NEXUS: Designed for travelers between the U.S. and Canada, NEXUS provides expedited clearance at land, sea, and air ports of entry. NEXUS members also receive TSA PreCheck benefits.
SENTRI: This program facilitates expedited entry into the U.S. from Mexico for pre-approved, low-risk travelers. SENTRI members also receive TSA PreCheck benefits.
The back of a Global Entry card clearly displays the PASSID, which serves as the Known Traveler Number, facilitating expedited security screenings.
2. Finding Your Known Traveler Number
Locating your KTN is a straightforward process, whether you have a Global Entry card or need to retrieve it online.
2.1. Where to Find Your KTN on a Global Entry Card
If you are a Global Entry member, your KTN, also known as your PASSID, is printed on the back of your Global Entry card. The number is a nine-digit identification code that you can use when booking flights.
2.2. How to Retrieve Your KTN Online
If you can’t find your physical card or need to access your KTN online, you can retrieve it through the Trusted Traveler Program (TTP) website. According to U.S. Customs and Border Protection, follow these steps:
- Go to the Trusted Traveler Program website.
- Log in to your account.
- Once logged in, you will find your PASSID, which is your KTN, on your account dashboard.
2.3. What to Do If You Can’t Find Your KTN
If you’ve misplaced your Global Entry card and can’t find your KTN online, you can contact the Trusted Traveler Program (TTP) directly for assistance. Here are the steps to take:
Check Your Email: Search your email for any communications from the TTP regarding your application approval. The email might contain your KTN or PASSID.
Contact the TTP Help Desk: Call the TTP help desk for assistance. You can find the contact number on the CBP website.
Visit a Global Entry Enrollment Center: If possible, visit a Global Entry Enrollment Center in person. Bring a valid government-issued ID for verification.
Airline Records: If you have previously used your KTN when booking flights, check your airline records or frequent flyer accounts. Your KTN might be stored in your profile.
3. Using Your Known Traveler Number
Using your KTN correctly is crucial for enjoying the benefits of expedited security screening.
3.1. How to Add Your KTN When Booking Flights
To ensure you receive TSA PreCheck benefits when flying, add your KTN to your airline reservations. Here’s how:
- During Online Booking: When booking your flight online, look for a section labeled “Known Traveler Number” or “TSA PreCheck.” This field is usually found in the personal information or passenger details section.
- Enter Your KTN: Type your nine-digit KTN into the designated field.
- Save Your Profile: If you have a frequent flyer account with the airline, save your KTN to your profile for future bookings.
3.2. How to Add Your KTN to Airline Profiles
Adding your KTN to your airline profiles ensures that the number is automatically included in all future bookings with that airline. Here’s how to do it:
- Log In: Log in to your frequent flyer account on the airline’s website.
- Account Settings: Navigate to the account settings or profile section.
- Update Information: Look for a field labeled “Known Traveler Number” or “TSA PreCheck” and enter your nine-digit KTN.

3.4. Common Mistakes to Avoid When Using Your KTN
To ensure your KTN works correctly, avoid these common mistakes:
Incorrect Entry: Double-check that you have entered your KTN correctly. Even a single wrong digit can prevent you from receiving TSA PreCheck benefits.
Expired Membership: Ensure that your Global Entry or TSA PreCheck membership is current. KTNs expire, and you need to renew your membership to continue enjoying the benefits.
Name Discrepancies: Make sure that the name on your airline ticket matches the name on your Global Entry or TSA PreCheck application. Discrepancies can cause issues with verification.
Using Someone Else’s KTN: Your KTN is unique to you. Using someone else’s KTN is a violation of the program rules and can lead to penalties.
3.5. Understanding TSA PreCheck and KTN
TSA PreCheck is an expedited security program that allows pre-approved travelers to experience faster and more efficient screening at U.S. airports. By providing your KTN when booking flights, you signal to the TSA that you are a trusted traveler, which grants you access to TSA PreCheck lanes.
Adding your Known Traveler Number (KTN) during flight booking ensures access to TSA PreCheck benefits for expedited security screening.

If your KTN is not working on your boarding pass, there are several possible reasons and steps you can take to resolve the issue:
