Check your status online using your Known Traveler Number

The fastest way to check your TSA PreCheck status is to visit the official TSA PreCheck website at tsa.gov/precheck and use their status checker tool. You will need your Known Traveler Number (KTN), which is an 10-digit code assigned when you enrolled. If you have your KTN, the status tool will show you whether your membership is active, pending, or expired in seconds.

If you do not have your KTN handy, you can find it in your email confirmation from when you enrolled, on your trusted traveler card if it was already issued, or in your airline frequent flyer account (many airlines display your KTN in your profile). Once you enter the number, the system will display your current membership status and the expiration date if your membership is active.

Key Takeaways

  • The TSA PreCheck status checker at tsa.gov/precheck is the official source and requires only your Known Traveler Number to show your membership status when ready.
  • Your Known Traveler Number appears in your enrollment confirmation email, on your trusted traveler card, or in your airline frequent flyer account profile.
  • Status results show whether your membership is active, pending approval, expired, or denied, along with your expiration date if approved.
  • If the status tool does not recognize your KTN, contact the TSA PreCheck customer service line at 1-855-347-8371 to verify your enrollment information.
  • Processing times for new enrollments typically range from two to four weeks, though some applications take longer depending on background check results.

What the status checker will tell you

The TSA PreCheck status tool returns one of four results. An active status means your membership is current and you can use your KTN when booking flights and at airport security. The tool will also show your expiration date so you know when to renew. A pending status means your process is still being processed, usually because the background check is underway. This can take two to four weeks from the date you enrolled.

A denied status means your process was not approved, typically due to criminal history, immigration issues, or other security concerns. The status tool does not explain the reason for denial. An expired status means your previous membership has lapsed and you will need to enroll again to regain PreCheck benefits. TSA PreCheck memberships last five years from the approval date.

What to do if your status shows pending

If your process is still pending after four weeks, you can contact TSA PreCheck customer service at 1-855-347-8371 to ask about the delay. Have your process confirmation number ready when you call. The representative can tell you whether your background check is still in progress or if additional information is needed from you.

Some applications are delayed because the TSA needs to verify information you provided during enrollment, such as your address history or name changes. If the TSA contacts you by email or phone asking for documents, respond as quickly as possible. Slow responses can extend the pending period by several weeks.

Finding your Known Traveler Number if you cannot locate it

If you enrolled in TSA PreCheck but cannot find your KTN, check your email inbox and spam folder for the enrollment confirmation message from the TSA. This email arrives within one business day of your in-person appointment and contains your 10-digit KTN. If you cannot find the email, log into your airline frequent flyer account and look for the KTN field in your profile settings—most major carriers display it there once it is issued.

If you have already received your physical trusted traveler card, your KTN is printed on the front. If you still cannot locate it after checking these places, call TSA PreCheck customer service at 1-855-347-8371 with your name, date of birth, and the email address you used to enroll. They can look up your KTN in their system and provide it to you over the phone.

Checking status through your airline account

Many airlines allow you to view your TSA PreCheck status directly in your frequent flyer account. Log into your airline's website or app, navigate to your profile or account settings, and look for a section labeled "Trusted Traveler" or "Known Traveler Number." If your KTN is linked to that account, the airline may also display your membership status and expiration date there.

This method is convenient if you already have your airline account open, but it depends on whether your airline has integrated TSA PreCheck status into their system. Not all carriers display this information. If your airline does not show the status, use the official TSA PreCheck status checker instead.

What happens after your membership expires

TSA PreCheck memberships are valid for five years from your approval date. About 90 days before your expiration date, the TSA will send you a renewal notice by email to the address on file. You can renew online through the TSA PreCheck website without attending an in-person appointment, which makes renewal faster than the initial enrollment.

If you do not renew before your membership expires, you will lose your PreCheck benefits when ready and will go through standard security screening on your next flight. You can renew at any time after receiving the notice, even if your membership has already expired. Processing for renewals typically takes two to three weeks.

Troubleshooting when the status tool does not work

If you enter your KTN into the status checker and receive an error message or no results, first verify that you typed the number correctly. The KTN is always 10 digits and contains only numbers. If the number is correct but the tool still does not recognize it, your enrollment may not have been processed yet, or there may be a data entry error in the TSA system.

Wait 24 hours and try again, as the system sometimes takes time to update after enrollment. If the problem persists after 24 hours, contact TSA PreCheck customer service at 1-855-347-8371. Have your process confirmation number and the email address you used to enroll ready. A representative can manually look up your status and help resolve any technical issues.

Frequently Asked Questions

How long does it take to hear back after I enroll in TSA PreCheck?

Most applicants receive a status update within two to four weeks of their in-person appointment. You will receive an email notification once your background check is complete and your membership is approved or denied. Some applications take longer if the TSA needs additional information from you or if your background check requires further review.

Can I use my KTN before my status shows active?

No. You can only use your KTN at airport security and when booking flights once your status shows active in the TSA PreCheck status checker. Using a KTN before approval will not give you PreCheck benefits and may cause confusion at the airport. Wait for your status to change to active before entering your KTN when booking.

What if the status checker says my process was denied?

The status tool does not explain why your process was denied. Contact TSA PreCheck customer service at 1-855-347-8371 to ask about the reason. You may be able to reapply after addressing the issue, such as resolving a background check concern or correcting information you provided during enrollment.

Is the TSA PreCheck status checker the same as the official TSA website?

The status checker is part of the official TSA website at tsa.gov/precheck. Make sure you are on the real TSA domain and not a third-party site that claims to check your status for a fee. The official TSA tool is always free and does not require payment or personal information beyond your KTN.

Can I check someone else's TSA PreCheck status?

No. The status checker requires the applicant's Known Traveler Number, which is personal information. You cannot look up another person's status without their KTN. If you are a parent or guardian trying to check a child's status, you will need the KTN from the child's enrollment confirmation.
