The fastest way to check your TSA PreCheck status

You can check whether you have an active TSA PreCheck membership by visiting the TSA PreCheck website at tsa.gov/precheck and using their "Check process Status" tool. You will need your Known Traveler Number (KTN), process receipt number, or the email address you used when you applied. The system will tell you when ready whether your membership is active, expired, or still pending.

If you do not have those details handy, you can also call the TSA PreCheck customer service line at 1-855-347-8371 during business hours. A representative can look up your status using your name and date of birth. This method takes longer but works if you have lost your process paperwork.

Your TSA PreCheck membership lasts five years from the date it was approved. If you applied more than five years ago, your membership has expired and you will need to reapply. The status checker will show you the exact expiration date.

Key Takeaways

  • Use the TSA PreCheck status tool on tsa.gov/precheck with your process receipt number, KTN, or email address to check your membership when ready.
  • Call 1-855-347-8371 if you do not have your process details and need a representative to look up your status by name and date of birth.
  • TSA PreCheck memberships are valid for five years from approval, and the status checker will show your exact expiration date.
  • If your membership has expired, you will need to submit a new process and pay the renewal fee to restore your benefits.

What your Known Traveler Number looks like

Your Known Traveler Number (KTN) is a 10-digit code assigned to you when your TSA PreCheck membership is approved. It appears on your approval letter and in any confirmation emails the TSA sent you. If you have booked flights, your airline may have already stored your KTN in your frequent flyer account or reservation.

You can find your KTN by logging into your airline's website and checking your profile or a past booking. Most airlines display it under "Frequent Flyer Information" or "Travel Preferences." If you have your boarding pass from a recent flight, the KTN may be printed on it as well.

Where to find your process receipt number

When you first submitted your TSA PreCheck process, you received a confirmation email with an process receipt number. This number looks like a string of letters and numbers and is the easiest way to check your status if you still have that email.

Check your email inbox and search for messages from tsa.gov or PreCheck. If you cannot find the original email, check your spam or trash folders—confirmation emails sometimes get filtered. If you have completely lost the receipt number, use your email address instead when you visit the status checker, or call customer service.

How to check your status on the TSA PreCheck website

Go to tsa.gov/precheck and look for the "Check process Status" button, usually located near the top of the page. Click it and you will be taken to a form asking for one of three pieces of information: your process receipt number, your KTN, or the email address associated with your account.

Enter whichever detail you have available and click "Check Status." The system will display your membership status within seconds. It will show whether your process is still being reviewed, whether you have been approved, or whether your membership has expired. If your status shows "approved," the page will also display your KTN and expiration date.

If the system cannot find your information, double-check that you entered it correctly. Common mistakes include using a different email address than the one on your process or mistyping your receipt number. If you are still stuck, call the customer service line.

What to do if your membership has expired

If the status checker shows that your TSA PreCheck membership expired, you will need to submit a renewal process. The renewal process is the same as the original process: you pay the renewal fee, complete the online form, and schedule an in-person appointment at an enrollment center to have your fingerprints taken and identity verified.

You can renew your membership up to six months before it expires, so you do not have to wait until the expiration date has passed. Renewing early means your new membership will begin when ready after your old one ends, with no gap in coverage. If you let it expire before renewing, you will lose your TSA PreCheck benefits at the airport until your new membership is approved.

What to do if your process is still pending

If the status checker shows your process is still being reviewed, the typical wait time is two to three weeks from your in-person appointment date. During this time, the TSA is conducting a background check and verifying the information you provided.

You can check your status as often as you like—there is no limit to how many times you can use the status tool. If your process has been pending for more than a month after your appointment, contact customer service to ask whether there is a delay or whether additional information is needed from you.

Frequently Asked Questions

Can I use TSA PreCheck at the airport if my process is still pending?

No. You can only use TSA PreCheck at security checkpoints once your membership is approved and you have received your KTN. Until then, you will go through standard security screening. Once approved, you can use your KTN when ready on future bookings.

What if the status checker says it cannot find my information?

First, verify you entered the correct email address, receipt number, or KTN—typos are the most common reason for "not found" results. If you are certain the information is correct, call 1-855-347-8371 and provide your name and date of birth so a representative can search manually.

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

You can renew up to six months before expiration, which is recommended to avoid a gap in benefits. If you wait until after it expires, you will lose TSA PreCheck access at the airport until your new membership is approved, which typically takes two to three weeks.

Will my KTN change if I renew my membership?

No. Your KTN stays the same when you renew. You do not need to update it with your airline or in your frequent flyer account. Only your expiration date will change.

Can I check someone else's TSA PreCheck status?

No. The online status tool requires personal information tied to the process. If you are checking on a family member's membership, they will need to check their own status or provide you with their receipt number or KTN.
