1. Understanding the Known Traveler Number (KTN)
A Known Traveler Number (KTN) is a unique identifier issued by the U.S. Department of Homeland Security (DHS) to individuals approved for Trusted Traveler programs like TSA PreCheck, Global Entry, NEXUS, and SENTRI. This nine-digit code, often a combination of letters and numbers, verifies your membership and allows you to access expedited security screening at U.S. airports. Think of it as your passport to a smoother, faster, and more convenient travel experience. According to the TSA, approximately 99% of TSA PreCheck passengers wait less than 10 minutes in security lines.

2. Who Needs a Known Traveler Number?
If you value time and convenience when traveling, a KTN is for you. It’s particularly beneficial for:
- Frequent Flyers: Those who travel multiple times a year for business or leisure.
- Families: Streamlining the security process for families traveling with children.
- Travelers Seeking Comfort: Enjoying a less intrusive screening experience without removing shoes, belts, or laptops.
- Anyone Valuing Time: Bypassing long security lines and saving precious time at the airport.
Imagine arriving at the airport and bypassing the long, winding security lines. With a KTN, this can be your reality.
3. Benefits of Having a Known Traveler Number
The advantages of possessing a KTN extend beyond mere convenience. Here’s a detailed breakdown:
- Expedited Security Screening: Access to TSA PreCheck lanes, which typically have shorter wait times.
- Less Intrusive Screening: Reduced need to remove shoes, belts, laptops, and liquids from your bag.
- Faster Processing: Streamlined security process allows you to reach your gate quicker.
- Peace of Mind: Reduced stress and anxiety associated with airport security.
- Global Entry Benefits: KTNs obtained through Global Entry provide expedited customs processing when returning to the U.S. from international travel.
According to the TSA, TSA PreCheck members experience significantly shorter wait times compared to standard security lanes. This translates to less stress and more time to relax before your flight.
4. Obtaining a Known Traveler Number: Trusted Traveler Programs
Several DHS-run Trusted Traveler programs offer a KTN upon approval. Let’s explore the most popular options:
4.1. TSA PreCheck

- TSA PreCheck Website: Use the DHS’s dedicated page to look up your KTN by providing personal information.
- Global Entry Card: Your KTN, also known as your PASSID, is printed on the back of your Global Entry card. It typically begins with “15,” “98,” or “99.”
- Trusted Traveler Program Account: Log in to your Global Entry, NEXUS, or SENTRI account on the DHS website to find your membership number/PASSID, which is your KTN.
- Airline Profile: Check your frequent flyer profile on airlines you regularly fly. Your KTN may be stored in your personal information section.
- Check your email: Search your email for the approval letter from the DHS after you were approved for your trusted traveler program. This letter will contain your KTN.

6. Adding Your Known Traveler Number to Travel Bookings
To ensure your KTN is recognized and printed on your boarding pass, you must add it to your airline profile and individual flight reservations.
6.1. Adding to Airline Profile
- Log in to your frequent flyer account on the airline’s website.
- Navigate to the personal information section of your profile.
- Locate the field labeled “Known Traveler Number,” “KTN,” or “Secure Traveler Information.”
- Enter your nine-digit KTN.
- Save your changes.
Once added to your airline profile, your KTN should automatically be included in all future bookings made with that airline, as long as you include your frequent flyer number on the reservation.
6.2. Adding to Existing Reservations
- Visit the airline’s website or use their mobile app.
- Retrieve your reservation using your confirmation number (record locator) and last name.
- Go to the traveler information section.
- Find the “Known Traveler Number” or similar field.
- Enter your KTN.
- Save the changes.
If you’ve already checked in for your flight, you may need to re-download your boarding pass for “TSA PreCheck” to appear.
7. What to Do if Your Boarding Pass Isn’t Marked “TSA PreCheck”
Even with a valid KTN, your boarding pass might not always display the “TSA PreCheck” indicator. Here’s what to do:
- Verify KTN Entry: Double-check that you entered your KTN correctly in your airline profile and/or reservation.
- Airline Error: Contact the airline to ensure your KTN is properly associated with your booking.
- Random Screening: In rare cases, even TSA PreCheck members may be subject to standard security screening due to random security protocols.
- TSA Agent Assistance: If the issue persists, speak to a TSA agent at the airport for assistance.
Don’t hesitate to address the issue promptly to avoid unnecessary delays.
8. Common Mistakes to Avoid When Using Your Known Traveler Number
To maximize the benefits of your KTN, avoid these common pitfalls:
- Incorrect KTN Entry: Ensure you enter your KTN accurately, as even a single digit error can prevent access to TSA PreCheck lanes.
- Expired Membership: Keep track of your Trusted Traveler program’s expiration date and renew your membership promptly to avoid interruption of benefits.
- Name Mismatch: The name on your airline ticket must exactly match the name on your Trusted Traveler program application. Any discrepancies can lead to issues at security.
- Forgetting to Add KTN: Always remember to add your KTN to your airline profile and individual reservations to ensure it’s reflected on your boarding pass.
By avoiding these mistakes, you can ensure a seamless and efficient airport security experience.

You can typically add your KTN to your reservation online or through the airline’s mobile app, even after booking.
Q5: Why isn’t “TSA PreCheck” printed on my boarding pass even though I have a KTN?
This could be due to an incorrect KTN entry, airline error, or random security protocols. Verify your KTN entry and contact the airline if needed.
