Where to Find Your TSA PreCheck Number

Your TSA Known Traveler Number (KTN) is a nine-character code assigned to you when you enroll in TSA PreCheck or another trusted traveler program. You can find it in three places: your enrollment confirmation email, your GOES account online, or by calling the TSA directly.

The fastest method is to log into your GOES account at goes.tsa.dhs.gov. This is the official government system that manages all TSA PreCheck enrollments. Once you sign in with your username and password, your KTN appears on your account dashboard under "Known Traveler Number" or "Membership Information." If you enrolled online, you received login credentials by email.

If you cannot access your GOES account, check your enrollment confirmation email from TSA. This message arrived within 24 hours of your enrollment and contains your KTN in the body of the email or as an attachment. Search your email inbox and spam folder for messages from "tsa@dhs.gov" or "PreCheck" if you cannot find it when ready.

Key Takeaways

  • Your TSA Known Traveler Number is a nine-character code you received when you enrolled in TSA PreCheck or another trusted traveler program.
  • The GOES website at goes.tsa.dhs.gov is the official place to view your KTN if you have your login credentials.
  • Your enrollment confirmation email from TSA contains your KTN and is usually the easiest document to locate if you saved it.
  • You can call the TSA at 1-855-347-8371 to have an agent look up your number if you cannot access your account or email.
  • You need your KTN when you book flights to receive TSA PreCheck screening benefits at the airport.

Logging Into Your GOES Account

Go to goes.tsa.dhs.gov and click "Sign In" in the upper right corner. You will be taken to a login page that asks for your username and password. These credentials were sent to your email address when you first enrolled in TSA PreCheck.

If you forgot your password, click "Forgot Password" on the login page and follow the prompts to reset it. TSA will send a reset link to the email address associated with your account. Once you log in successfully, your dashboard displays your membership status, expiration date, and your nine-digit KTN. Write down the number or take a screenshot so you have it when you book your next flight.

If you never received login credentials or cannot remember your username, contact the TSA at 1-855-347-8371. An agent can help you recover your account or create a new login if your old one is no longer accessible.

Finding Your Number in Your Confirmation Email

When you enrolled in TSA PreCheck, you received a confirmation email from TSA within one business day. This email contains your KTN and is often the quickest way to locate it if you saved the message.

Open your email and search for messages from "tsa@dhs.gov" or with the subject line "TSA PreCheck Enrollment Confirmation" or "Known Traveler Number." The KTN appears in the email body, usually near the top, and is labeled clearly as "Known Traveler Number" or "KTN." If you cannot find the email in your inbox, check your spam or promotions folder—TSA emails sometimes land there by mistake.

If you deleted the email and cannot recover it, do not worry. You can still retrieve your number through the GOES website or by calling TSA. The confirmation email is convenient but not the only way to access your KTN.

Calling TSA to Look Up Your Number

If you do not have access to your GOES account or your confirmation email, you can call the TSA directly at 1-855-347-8371. This line is available Monday through Friday, 8 a.m. to 10 p.m. Eastern time, and Saturday and Sunday, 9 a.m. to 8 p.m. Eastern time.

When you call, have your passport number or driver's license number ready. The agent will ask for identifying information to confirm your identity before sharing your KTN. The call usually takes five to ten minutes. Write down your number as the agent reads it to you, and ask them to spell it if needed to make sure you have it correct.

Wait times can be long during peak travel seasons, so consider calling early in the morning or on a weekday if possible. If you reach a busy signal, try again later rather than waiting on hold for an extended period.

What to Do If Your KTN Is Expired or Invalid

TSA PreCheck membership lasts five years from your enrollment date. If your KTN is expired, you will need to renew your membership through the GOES website before you can use it for flights.

Log into your GOES account and look for a "Renew" button on your dashboard. The renewal process is shorter than the initial enrollment and costs the same as a new membership. You will not need to visit an enrollment center again—you can renew entirely online. Once your renewal is approved, your new KTN will appear in your account within one to two business days.

If your KTN appears invalid when you enter it during flight booking, double-check that you typed it correctly. The number is nine characters long and may include both letters and numbers depending on which trusted traveler program you enrolled in. If the number is correct and still does not work, contact your airline's customer service to troubleshoot the issue.

Using Your KTN When You Book a Flight

Once you have your KTN, enter it in the "Known Traveler Number" field when you book your flight online or over the phone. Most airline websites have a dedicated field for this information on the passenger details page. If you do not see it, look for a link that says "Add TSA PreCheck" or "Trusted Traveler Information."

You can also add your KTN to your airline frequent flyer profile so it automatically fills in every time you book. This saves time on future reservations. If you book through a travel website like Expedia or Kayak, you may need to enter your KTN separately when you complete your purchase with the airline.

Your KTN must match the name on your ticket and passport exactly. If you recently changed your name, update it in your GOES account before booking to avoid problems at the airport.

Frequently Asked Questions

What if I enrolled in TSA PreCheck but never received a confirmation email?

Check your spam and promotions folders first—TSA emails sometimes get filtered. If you still cannot find it, log into your GOES account at goes.tsa.dhs.gov to view your KTN there. If you cannot access your account, call 1-855-347-8371 and an agent will look up your number for you.

Can I use my KTN if my TSA PreCheck membership expired?

No, your KTN is only valid while your membership is active. You will need to renew your membership through the GOES website before your KTN will work for flights. Renewal takes one to two business days after approval.

Do I need to print my KTN or show it at the airport?

No, you do not need to print anything. The TSA receives your KTN electronically when you enter it during flight booking. Just show your ID and boarding pass at security. The TSA agent will see your PreCheck status on their system.

What if I have multiple trusted traveler programs—do I have more than one KTN?

Yes, each program has its own KTN. TSA PreCheck, Global Entry, NEXUS, and SENTRI each issue separate numbers. When you book a flight, use the TSA PreCheck KTN specifically, not a number from another program.

How do I know if my KTN is correct when I enter it during booking?

Your KTN is nine characters long. When you enter it correctly during booking, the airline system will confirm your TSA PreCheck status. If the number is rejected, check that you typed it exactly as it appears in your GOES account—no extra spaces or characters.
