The fastest way to check your TSA PreCheck status

You can check whether you have an active TSA PreCheck membership in three ways: look at your boarding pass, check the TSA website with your known traveler number, or call TSA directly. The easiest method is to log into your airline's website or app and look at a recent or upcoming boarding pass — if you have PreCheck, your known traveler number (KTN) will appear in the confirmation details, and your boarding pass will show "TSA Pre✓" near your name.

If you don't have a boarding pass handy, go to the TSA PreCheck website at universalenroll.dhs.gov and enter your process receipt number or known traveler number. The system will show your membership status and expiration date. If you've lost your receipt number, you can also call the TSA PreCheck program at 855-347-8371 and provide your name, date of birth, and driver's license number to confirm your status over the phone.

Key Takeaways

  • Your boarding pass is the quickest indicator — look for "TSA Pre✓" printed next to your name and your known traveler number in the confirmation details.
  • The TSA PreCheck website at universalenroll.dhs.gov lets you check your status and expiration date using your receipt number or known traveler number.
  • If you don't remember your known traveler number, call 855-347-8371 with your name, date of birth, and driver's license information.
  • An active membership lasts five years from your approval date, so check the expiration date to know when you'll need to renew.

What to look for on your boarding pass

When you book a flight, your airline asks for your known traveler number during the reservation process. If you enter it correctly and your TSA PreCheck membership is active, the confirmation email and boarding pass will display "TSA Pre✓" in the passenger information section. This appears on both paper and mobile boarding passes.

The known traveler number itself is a 10-digit code that begins with letters — for example, "ABC1234567D". It's printed on your TSA PreCheck card and in your approval email. If your boarding pass doesn't show "TSA Pre✓" even though you entered your known traveler number, your membership may have expired, or there may be a mismatch between the number you entered and the one in the TSA system.

Using the TSA PreCheck website to verify your status

Go to universalenroll.dhs.gov and click "Check process Status" in the upper right corner. You'll be asked to enter either your process receipt number (a 10-digit code from your original approval email) or your known traveler number. The system will display your membership status, approval date, and expiration date.

If you don't have your receipt number or known traveler number, you can still look them up by entering your full name, date of birth, and the email address you used when you applied. The system will search for your process and show you the information. Write down your known traveler number and save it somewhere safe — you'll need it every time you book a flight to receive PreCheck benefits.

Calling TSA PreCheck customer service

If you prefer to speak with someone, call the TSA PreCheck program at 855-347-8371. The line is open 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. Have your driver's license or passport ready, along with your name and date of birth.

The representative can confirm whether you have an active membership, tell you your expiration date, and provide your known traveler number if you've forgotten it. They can also help if you believe there's an error in the system or if your membership status seems incorrect.

Understanding your membership timeline

TSA PreCheck memberships are valid for five years from the date you were approved, not from the date you paid the fee or completed your in-person appointment. Your approval email will show the exact date your membership began. To find your expiration date, add five years to that approval date.

About three months before your membership expires, you'll become may be able to access to renew at a reduced rate (usually around $70 to $85 instead of the full $78 to $85 fee, depending on your state). You can renew online through the TSA PreCheck website without scheduling another in-person appointment, though some states may require a brief visit to confirm your identity.

What happens if your membership has expired

If your TSA PreCheck membership has expired, you will no longer see "TSA Pre✓" on your boarding pass, even if you enter your known traveler number during booking. You'll go through standard security screening instead of the expedited PreCheck lane. Your known traveler number remains yours and can be reactivated if you renew your membership.

To renew, return to universalenroll.dhs.gov and select the renewal option. You can complete the renewal process online and pay the fee. Depending on your state, you may be able to skip the in-person appointment entirely, or you may need to visit an enrollment center for a quick identity verification. The renewal process is faster than the original process and usually takes two to four weeks.

Frequently Asked Questions

What if my known traveler number isn't showing up on my boarding pass?

First, check that you entered the number correctly when you booked your flight — a single wrong digit will prevent it from appearing. If you entered it correctly, your membership may have expired. Verify your status on the TSA PreCheck website or call 855-347-8371 to confirm. If your membership is active, contact your airline's customer service to see if there's a system error on their end.

Can I use someone else's known traveler number on my boarding pass?

No. Your known traveler number is tied to your identity and your TSA PreCheck membership. Using someone else's number is fraud and will result in serious legal consequences. Each person who wants PreCheck benefits must have their own active membership.

Do I need to renew my TSA PreCheck before it expires?

You can renew up to six months before your membership expires. The TSA recommends renewing about three months before expiration to avoid any gap in your PreCheck benefits. If your membership expires before you renew, you'll lose PreCheck access on your boarding passes until the renewal is processed.

What if I lost my TSA PreCheck card?

Your card is just a physical copy of your known traveler number — losing it doesn't affect your membership status. You can still use PreCheck by providing your known traveler number when you book flights. If you want a replacement card, contact the TSA PreCheck program at 855-347-8371 or visit an enrollment center.

How long does it take to get TSA PreCheck after I'm approved?

Once you're approved, you can use your known traveler number on boarding passes when ready. Your physical card will arrive in the mail within two to four weeks. You don't need to wait for the card to start using your PreCheck benefits — the known traveler number is what matters at the airport.
