Your Known Traveler Number for Global Entry is usually your PASSID. You can find it in your Trusted Traveler Programs account or on the back of your Global Entry card. Use the exact name and number listed there to match your airline reservation. Trouble signing in or updating a booked flight can make the process a bit tricky, so it helps to know where to look next.
Your PASSID Is Your Known Traveler Number
Should you’re trying to find your Known Traveler Number for Global Entry, use your PASSID. For compliance purposes, treat them as the same identifier. Under the PASSID definition, this nine-digit number links your approved Trusted Traveler membership to airline reservations and TSA PreCheck eligibility. You’re part of the expedited screening program once that number is entered correctly.
Focus on membership number basics before you travel.
Check your Global Entry card and confirm the nine-digit PASSID printed on it matches your records. Use that exact number once you book flights, update traveler profiles, or correct reservation details. Don’t substitute another account number or omit digits. Airlines recognize your PASSID as your KTN, so accuracy keeps your benefits active and helps you move through screening with confidence and belonging every trip.

Should you belong to Global Entry, NEXUS, or SENTRI, the PASSID functions as your Known Traveler Number. This method keeps you within official DHS channels and helps you stay aligned with your trusted traveler benefits every time you book flights.
Find Your PASSID on Your Global Entry Card
Check the back of your Global Entry card and look in the upper left-hand corner for your PASSID.
You’ll see a nine-digit number there, and that number serves as your Known Traveler Number.
Verify that you enter all nine digits exactly as shown to keep your travel profile compliant.
PASSID Card Location
On your Global Entry card, you’ll find your Known Traveler Number as the nine-digit PASSID printed on the back. Check the card back initially, then look to the upper left area. That placement helps you confirm you’re using the correct member identifier issued with your approved account.
- Turn your card over before searching the front.
- Focus on the upper left section of the card back.
- Locate the label for PASSID on that side.
- Compare what you see with your travel records.
- Keep the card accessible for quick, compliant verification.
If you’re preparing a booking, copy the PASSID exactly as shown on the card. Use only your own approved Global Entry card, and store it securely after checking. That keeps your information organized, accurate, and ready anytime trusted travel benefits matter most.
PASSID Number Format
Precision matters whenever you identify your PASSID, because your Global Entry Known Traveler Number appears as a nine-digit number only. You should confirm every digit before entering it in an airline profile or reservation. Don’t add letters, spaces, or punctuation. Your PASSID digits must appear exactly as issued by Customs and Border Protection to keep your Trusted Traveler benefits active and correctly matched.
When you review the card or TTP dashboard, check the full nine-digit sequence and compare common number patterns. Global Entry PASSIDs may begin with 10, 13, 14, 15, 16, 50, 70, 80, 95, 98, or 99. These prefixes help you recognize a valid format, but you still need an exact match. If one digit is wrong, your booking may miss PreCheck access and delay your airport experience.
Use Your KTN When Booking Flights
When you book a flight, enter your Known Traveler Number exactly as it appears in your Global Entry account or on the back of your card as the nine-digit PASSID. This keeps your reservation compliant and helps you receive booking benefits tied to TSA PreCheck.
- Add the PASSID in the airline’s KTN or Trusted Traveler field.
- Match your full name, date of birth, and gender to your Global Entry record.
- Save the number in frequent flyer accounts and reservation profiles for future bookings.
- Confirm the KTN appears on your confirmation email or trip summary.
- Check for the TSA PreCheck indicator on your boarding pass before travel.
Add Your Known Traveler Number to Existing Trips
Should you already booked a trip, add your Global Entry Known Traveler Number to the reservation as soon as possible so the airline can transmit it for TSA PreCheck screening. Open your airline app or website, access your booking, and complete any required reservation edits. Enter your nine-digit PASSID exactly as issued, then save the changes.
When online trip updates aren’t available, contact the airline directly and ask an agent to add the number to each flight segment. Verify your name, date of birth, and gender match your booking and Trusted Traveler record.
Then review your boarding pass after check-in for the TSA PreCheck indicator. When it doesn’t appear, request a correction before you reach security. Taking these steps helps you travel with confidence and stay aligned with program requirements every time.
Recover Your Global Entry Login
If you can’t access your Global Entry account, recover your login through the Trusted Traveler Program website at ttp.dhs.gov before trying to look up your Known Traveler Number. Use the official account recovery options and follow each prompt exactly to protect your membership record and stay aligned with program requirements.
- Select Forgot Username or Forgot Password on the TTP sign-in page.
- Enter your email and personal details exactly as your enrollment records show.
- Complete identity verification steps to continue the account recovery process securely.
- Use the password reset link promptly, then create a strong, unique password.
- Sign in again and confirm your dashboard opens without profile errors.
If recovery fails, contact TTP support through the website. Keep your information consistent so your account remains accessible and your travel profile stays current.
Find Your KTN If You Lost Your Card
Two reliable options let you find your Global Entry KTN after losing your card. First, sign in to your Trusted Traveler Programs account at ttp.dhs.gov. On the Dashboard, locate your nine-digit PASSID at the top; that number is your KTN. Confirm the account belongs to you before using it on reservations.
Second, review an airline profile or prior booking where you previously entered the number. Many carriers store it in your frequent flyer account or trip history. Use this only as a backup and verify it matches your TTP record exactly.
If you need a lost card replacement, handle membership number recovery first so you can keep TSA PreCheck benefits active on future bookings. Following these steps helps you stay travel-ready and connected to trusted traveler benefits nationwide.
Fix Name Mismatches for TSA PreCheck
When TSA PreCheck doesn’t appear on your boarding pass, check that the name on your reservation matches your Global Entry record exactly. Even small differences can block recognition. Use these name matching tips and follow profile correction steps promptly so your membership works smoothly and you stay aligned with program requirements.
- Compare your airline reservation, passport, and TTP profile character by character.
- Keep hyphens, apostrophes, middle names, and suffixes consistent everywhere.
- Confirm your nine-digit PASSID/KTN is entered in the airline profile correctly.
- Update errors through your airline account or the TTP dashboard, based on where they start.
- Reissue the reservation after corrections if PreCheck still doesn’t display.
If a legal name changed, update government documents first, then revise your TTP and airline records before traveling.
Frequently Asked Questions
Does Global Entry Membership Guarantee TSA Precheck on Every Flight?

How Long Does It Take to Receive a Global Entry Card?
Most applicants receive a Global Entry card within two to four weeks after approval. Review your TTP account for updates, verify that your mailing address is correct, and watch for delivery so your records stay current.

Yes, you can use your Known Traveler Number when booking with international airlines that participate in TSA PreCheck. About 200 U.S. airports support the program. Enter your PASSID exactly as issued and confirm that the airline has verified it so your reservation remains valid.
What Should I Do if My Global Entry Membership Expired?
Log in to the Trusted Traveler Programs website and file your renewal as soon as possible, then check your application status regularly. If you wait too long, your Global Entry and TSA PreCheck benefits may stop until U.S. Customs and Border Protection finishes reviewing and approves your renewal.
