Where to find your TSA PreCheck number

Your TSA PreCheck number is printed on your Known Traveler Number (KTN) card, which arrives in the mail after your process is approved. The nine-digit number appears on the front of the card in the upper right corner. If you have the physical card, that is the fastest way to locate it.

If you have lost the card or do not have it nearby, you can retrieve your number through the TSA's official website or by contacting TSA directly. The process takes a few minutes and requires information from your original process.

Key Takeaways

  • If you do not remember your process ID, you can call the TSA at 1-855-347-8371 to retrieve it using your name and date of birth.

Using the TSA website to retrieve your number

Go to the official TSA PreCheck website at universalenroll.dhs.gov. Click on "Sign In" and enter your process ID and date of birth. Your process ID was sent to you in an email when you submitted your process, and it typically starts with letters followed by numbers.

Once you log in, your account dashboard will display your TSA PreCheck number along with your approval status and card expiration date. You can screenshot or write down the number for your records. This method works whether your card is on the way, already arrived, or lost.

Calling the TSA if you cannot find your process ID

If you do not have your process ID, call the TSA PreCheck customer service line at 1-855-347-8371. Have your full name, date of birth, and the email address you used when you applied ready. The representative can look up your account and provide your TSA PreCheck number over the phone.

Customer service is available Monday through Friday from 8 a.m. to 10 p.m. Eastern time, and Saturday and Sunday from 9 a.m. to 8 p.m. Eastern time. Wait times are typically shorter on weekday mornings.

What to do if your card has not arrived

TSA PreCheck cards usually arrive within two weeks of approval, though processing can take up to three weeks in some cases. You do not need to wait for the physical card to use your TSA PreCheck number — you can provide it to airlines as soon as your process is approved.

When you book a flight or check in at the airport, enter your nine-digit TSA PreCheck number in the "Known Traveler Number" field. The airline will flag your reservation, and you will be directed to the TSA PreCheck security lane at the airport. If your card has not arrived after three weeks, contact the TSA customer service line to confirm your address is correct.

Using your number when you travel

Provide your TSA PreCheck number to the airline when you book your flight online. Most airline websites have a field labeled "Known Traveler Number" or "KTN" in the passenger information section. You can also add it at check-in if you did not enter it during booking.

At the airport, present your ID and boarding pass to the TSA officer. If your number was entered correctly, you will be directed to the TSA PreCheck lane, where you can keep your shoes, belt, and light jacket on, and leave your laptop and liquids in your carry-on bag. TSA PreCheck is valid for five years from the date of approval.

If you have lost or damaged your card

A lost or damaged card does not affect your TSA PreCheck status. Your nine-digit number remains active and valid. You can continue to use it for travel without the physical card — airlines and TSA only need the number itself.

If you want a replacement card, you can request one through your account on the TSA PreCheck website or by calling customer service. There is no fee for a replacement card. The new card will be mailed to the address on file and typically arrives within two to three weeks.

Frequently Asked Questions

Can I use my TSA PreCheck number before my card arrives?

Yes. Your number is active as soon as your process is approved. You do not need the physical card to use TSA PreCheck at the airport — the airline and TSA only need the nine-digit number. Provide it when you book your flight or at check-in.

What if I forgot my TSA PreCheck number and do not have my card?

Log into your account at universalenroll.dhs.gov using your process ID and date of birth, and your number will appear on your dashboard. If you do not remember your process ID, call 1-855-347-8371 and provide your name and date of birth, and a representative will retrieve it for you.

Is my TSA PreCheck number the same as my Known Traveler Number?

Yes, they are the same thing. TSA PreCheck is the program, and your Known Traveler Number (KTN) is the nine-digit code you receive. Airlines and TSA use the terms interchangeably when asking for your number at booking or check-in.

How long is my TSA PreCheck number valid?

Your TSA PreCheck number is valid for five years from the date your process was approved. Your card will show an expiration date. You will need to renew your TSA PreCheck before that date if you want to continue using the program.
