There's no physical PreCheck card and no app that shows your expiration date front and center. Here are the three reliable ways to find it, plus what to do if your record has gone missing.
Go to the official TSA PreCheck KTN Lookup tool at universalenroll.dhs.gov/programs/tsa-precheck/lookup. Enter your full legal name (matching your application) and date of birth, then submit. The tool returns your Known Traveler Number and your current membership status — active or expired — along with the expiration date if your record is active.
This is the only place to get the official date in writing. Airline profiles show your KTN but not always your expiration. Boarding passes show whether PreCheck was applied for that flight, but not when it ends.
Use the official tool first. The other two are useful when you just need a quick check.
Go to universalenroll.dhs.gov/programs/tsa-precheck/lookup. Enter name and date of birth. Returns KTN, status, and expiration date. The authoritative source.
Log into your airline account. Look under "Known Traveler Number" or "Secure Traveler" in your profile. Most carriers display the KTN but not the expiration — useful for cross-checking.
"TSA PRE" or "TSA PRECHK" printed near your name confirms your KTN is active right now. No print means it's expired, blocked, or wasn't entered into the booking.
If your PreCheck benefit comes from Global Entry, NEXUS, or SENTRI rather than a standalone PreCheck application, the TSA PreCheck KTN Lookup tool won't find you. Use your trusted traveler PASSID through ttp.cbp.dhs.gov instead. The PASSID functions as your KTN, and the same dashboard shows your expiration.
Global Entry, NEXUS, and SENTRI memberships are also five years. They expire on their own schedule — having Global Entry doesn't extend PreCheck or vice versa.
The most common reason a lookup fails is a small name mismatch — a middle name on file that you didn't enter, a hyphenated last name, an old name from before a change. Try a few variations of your name first.
If that doesn't work, call the TSA Contact Center at 866-289-9673 (Monday to Friday, 8am–11pm ET; weekends and holidays 9am–8pm) or email askTSA@tsa.dhs.gov. They can locate records the public tool can't. If your membership expired more than a year ago, you may need to enroll again rather than renew — the record gets archived out of the active system.
Looking up your expiration is something you should only have to do once. Once you have the date, the smart move is to set a reminder ahead of it so the next renewal can never sneak up on you. Six months before is the right anchor — that's when the renewal window opens and when you'd want to start the process.
See the full TSA PreCheck renewal reminder guide or learn more about when to renew without losing time.
Set the reminder now — pick a date six months before your expiration.
Done in seconds. No sign-up required.
The fastest place is your airline frequent-flyer profile under "Known Traveler Number." Your most recent boarding pass also shows whether PreCheck was applied. For the official record, use the TSA PreCheck KTN Lookup tool at universalenroll.dhs.gov.
KTN stands for Known Traveler Number. It's a nine-digit number issued when your PreCheck application is approved. You enter it into airline profiles to get PreCheck on your boarding passes. If you've lost it, use the official KTN Lookup tool at universalenroll.dhs.gov/programs/tsa-precheck/lookup.
Yes. The TSA PreCheck KTN Lookup tool at universalenroll.dhs.gov returns your KTN and current membership status (active or expired) when you enter your name and date of birth. Global Entry, NEXUS, and SENTRI members look up their PASSID through ttp.cbp.dhs.gov instead.
If your expiration date is within six months, you're in the renewal window. The new five-year term starts when your current one ends, so renewing early costs you no time. If your KTN no longer triggers PreCheck on boarding passes, your membership has already expired.
The KTN itself doesn't expire as a number — your PreCheck membership does, after five years. The same KTN can be reissued or remain with your renewed membership. If you let your membership lapse and reapply later, you may receive a new KTN.
Contact the TSA Contact Center at 866-289-9673 or askTSA@tsa.dhs.gov. They can locate your record if the lookup tool returns nothing — usually because of a name mismatch with what's on file. If your membership has expired and the record is too old to recover, you'll need to enroll again.
Once you know your expiration date, set a reminder six months ahead. We'll email you in time to renew, with follow-ups until you're done.
