Where to Find Your TSA PreCheck Number

Your TSA PreCheck number is printed on your Known Traveler Number (KTN) card, which TSA mails to you after your process is approved. The nine-digit number appears on the front of the card in the upper right corner. If you have your physical card, that is the fastest way to locate it.

If you cannot find your card, you can retrieve your number through the TSA PreCheck website or by contacting TSA directly. The easiest online method is to log into your account at the official TSA PreCheck enrollment website using the same credentials you created when you first submitted your process. You can also find the number in your approval email or by calling customer service.

Key Takeaways

  • Your TSA PreCheck number is a nine-digit code printed on the front of your physical KTN card in the upper right corner.
  • You can view your number by logging into your TSA PreCheck account at the official enrollment website with your username and password.
  • If you do not have online access, you can call the TSA PreCheck customer service line at 1-855-347-8371 to request your number over the phone.
  • You will need your number when booking flights, so write it down or save it in your phone for quick reference at the airport.
  • Your approval email from TSA contains your nine-digit number, so check your inbox including spam and promotions folders if you cannot locate your card.

Logging Into Your TSA PreCheck Account Online

Visit the official TSA PreCheck enrollment website and select the login option. Enter the username and password you created during your initial process. Once you are logged in, your account dashboard will display your KTN and your nine-digit TSA PreCheck number clearly at the top of the page.

If you forgot your password, the website has a password reset option on the login page. You will need to verify your identity by answering security questions or confirming information from your process. This process typically takes a few minutes, and you will receive a temporary password via email that you can use to log in and create a new permanent password.

Calling TSA PreCheck Customer Service

If you prefer to speak with someone directly, call the TSA PreCheck customer service line at 1-855-347-8371. The line is open Monday through Friday from 8 a.m. to 10 p.m. Eastern time and Saturday and Sunday from 9 a.m. to 8 p.m. Eastern time. Have your driver's license or passport number ready when you call, as the representative will need it to verify your identity.

The representative will confirm your identity and provide your nine-digit number over the phone. They can also answer questions about your account status, tell you when your physical card should arrive, or help if your card was lost or damaged. This method works well if you need your number when ready and do not have access to your email or online account.

Checking Your Email Confirmation

When TSA approved your PreCheck process, they sent a confirmation email with your KTN and TSA PreCheck number. Search your email inbox (including spam and promotions folders) for messages from TSA PreCheck using keywords like "approval," "congratulations," or "KTN." The number will be listed clearly in that email along with instructions for using it.

If you cannot locate the original approval email, you can request TSA to resend it by contacting customer service at 1-855-347-8371. Keep this email in a safe place for your records, since you may need to reference your number in the future or if you need to prove your enrollment status to an airline.

What to Do If You Cannot Find Your Number

If you have lost your card, cannot access your online account, and cannot find your approval email, contact TSA PreCheck customer service at 1-855-347-8371. They can verify your identity using information from your process and provide your number when ready over the phone. You can also request a replacement card if yours was damaged or lost in the mail.

There is a fee for replacement cards, which varies depending on how much time remains on your current membership. TSA will mail the new card to the address on file, which typically arrives within two to three weeks. In the meantime, you can use your nine-digit number right away when booking flights, even without the physical card in hand.

Using Your Number When You Book a Flight

When you purchase an airline ticket online or through a travel agent, enter your nine-digit TSA PreCheck number in the "Known Traveler Number" field during checkout. This tells the airline that you are enrolled in the program. The airline will then add a TSA PreCheck indicator to your boarding pass, usually shown as "TSA Pre✓" or similar notation.

At the airport, present your boarding pass and a valid government-issued ID at the TSA PreCheck security lane. You will not need to remove your shoes, belt, light jacket, or laptop from your bag. Keep your TSA PreCheck number saved in your phone or written down so you can enter it quickly when booking future flights, which saves time at checkout.

Frequently Asked Questions

Is my TSA PreCheck number the same as my Known Traveler Number?

Your TSA PreCheck number and your Known Traveler Number (KTN) are the same nine-digit code. TSA uses both terms interchangeably. When an airline or TSA asks for your KTN, provide your TSA PreCheck number.

What if I have a TSA PreCheck card but cannot read the number?

If the number on your card is faded or damaged, contact TSA PreCheck customer service at 1-855-347-8371 and they will read it to you over the phone. You can also request a replacement card if the damage is severe enough that the number is illegible.

Can I use my TSA PreCheck number before I receive my physical card?

Yes. Once your process is approved, TSA sends you a confirmation email with your nine-digit number. You can use this number when ready when booking flights, even if your physical card has not arrived yet. Just enter the number in the Known Traveler Number field during checkout.

Do I need to memorize my TSA PreCheck number?

You do not need to memorize it, but it is helpful to save it somewhere accessible, like your phone or a note in your wallet. You will need to enter it every time you book a flight, so having it readily available saves time at checkout.

What should I do if my TSA PreCheck number is not working at the airport?

If your boarding pass does not show the TSA PreCheck indicator, inform the TSA officer at the security checkpoint. They can manually verify your enrollment status using your ID and may still allow you through the PreCheck lane. Contact customer service after your trip to find out why the number did not appear on your boarding pass.
