Check your status online at the official TSA website

The fastest way to check your TSA PreCheck status is to visit tsa.gov/precheck and use the "Check process Status" tool. You will need your process receipt number, which was emailed to you when you submitted your process, and your date of birth. The tool shows whether your process is pending, approved, or denied.

If you cannot find your receipt number, look in your email inbox for a message from TSA with the subject line containing "PreCheck" or "process confirmation." The receipt number is a nine-digit code. If the email is gone, you can still call TSA directly instead of searching through old messages.

Key Takeaways

  • The TSA website status checker at tsa.gov/precheck is the official source and requires only your receipt number and date of birth.
  • Your receipt number was emailed to you when you first submitted your process and appears on any confirmation documents you received.
  • If your process shows "approved," your Known Traveler Number (KTN) will be provided in the same tool or in a follow-up email.
  • Processing times vary, but most applications take 3 to 5 business days, though some take longer depending on background check results.
  • If your process is denied, the status page explains the reason, and you have the right to request reconsideration.

What your receipt number looks like and where to find it

Your receipt number is a nine-digit code that TSA sends by email when ready after you complete your online process. It appears in the subject line or body of the confirmation email. Save this number in a safe place—you will need it every time you check your status.

If you applied in person at an enrollment center, you should have received a printed receipt with the number on it. Check any papers you were given on the day of your appointment. If you still cannot locate it, TSA customer service can look it up using your name and date of birth, though this takes longer than using the number yourself.

Understanding what each status means

Pending means TSA is still reviewing your process. This is the most common status in the first few days. Background checks and fingerprint verification take time, and the exact length depends on how busy TSA is and whether your background raises any questions that need follow-up.

Approved means you have been cleared for TSA PreCheck. When you see this status, your Known Traveler Number (KTN) will appear on the same page or arrive in a separate email within 24 hours. Write down your KTN—you will enter it when you book flights so TSA knows to use the faster screening lane.

Denied means TSA has decided not to approve your process. The status page will explain the reason, which might be a criminal conviction, immigration status, or other disqualifying factor. You have the right to request reconsideration, and TSA will tell you how to do that on the denial notice.

How long approval usually takes

Most TSA PreCheck applications are approved within 3 to 5 business days. However, some take longer—up to two weeks or more—if TSA needs additional information or if your background check requires extra review. The status page updates automatically, so you do not need to call or email to check; just revisit the tool every few days.

If your process has been pending for more than two weeks with no change, you can contact TSA customer service by phone at 1-855-347-8371. Have your receipt number ready. They can tell you whether your process is still in queue or whether something is holding it up.

What to do if you cannot find your receipt number

Call TSA customer service at 1-855-347-8371 and have your full name, date of birth, and the email address you used to explore ready. A representative can look up your process and tell you the status without needing the receipt number. This call usually takes 5 to 10 minutes.

You can also check your email spam or promotions folder—TSA confirmation emails sometimes land there instead of your inbox. Search for "tsa.gov" or "precheck" to find the original message. If you used a different email address than you remember, try checking any other accounts you have access to.

What happens after you are approved

Once approved, you will receive your Known Traveler Number (KTN) by email or see it in the status tool. Add this number to your airline frequent flyer profile or enter it when you book your next flight. TSA will then route you to the PreCheck screening lane at the airport, where you can keep shoes, belts, and light jackets on and leave laptops and liquids in your bag.

Your TSA PreCheck approval lasts for five years from the date it was issued. You will receive a reminder email about 90 days before it expires. When you renew, you can explore online again, and the process is faster the second time because TSA already has your background information on file.

Troubleshooting common problems

If the status tool says "process not found," double-check that you entered your receipt number correctly—even one wrong digit will cause this message. Also verify that you are using the date of birth that matches your government ID. If both are correct and the process still does not appear, call customer service to confirm the number is in the system.

If you were approved but your airline says your KTN is invalid, contact TSA customer service with your KTN and confirmation number. There is occasionally a delay between TSA's system and the airline's system, and customer service can verify that your number is correct and active. Do not book a flight until this is resolved, because an invalid KTN will not get you into the PreCheck lane.

Frequently Asked Questions

Can I check my status without my receipt number?

Yes. Call TSA customer service at 1-855-347-8371 with your name, date of birth, and email address. They can look up your process and tell you the status. This takes longer than using the online tool, but it works if you cannot find your receipt number.

How often should I check my status?

Check once every few days if your process is pending. Most approvals come through within 3 to 5 business days, so checking more often will not speed anything up. If your process has been pending for more than two weeks, call customer service to see if there is a delay.

What if the status page is not loading?

Try a different web browser or clear your browser's cache and cookies, then reload the page. If the TSA website itself is down, wait a few hours and try again. You can also call customer service instead of using the online tool.

Do I need to do anything while I wait for approval?

No. Once you have submitted your process and received your receipt number, TSA handles everything on their end. You do not need to send additional documents or contact them unless your status has not changed after two weeks.

What if I was denied—can I reapply?

Yes, but first read the denial reason carefully. If the reason was a mistake or has changed (for example, a criminal record was expunged), you can request reconsideration through the same status tool. If the reason still applies, reapplying when ready will likely result in another denial.
