How to learn about you already have TSA PreCheck

You have TSA PreCheck if you received a Known Traveler Number (KTN) after going through the TSA PreCheck enrollment process and paying the fee. The fastest way to check is to log into your TSA PreCheck account at universalenroll.dhs.gov using the same email address you used when you enrolled. If your account shows an active membership with an expiration date in the future, you have TSA PreCheck.

If you do not remember whether you enrolled, check your email for a confirmation message from TSA PreCheck. These emails typically arrive within a few days of your in-person appointment and include your KTN. You can also call the TSA PreCheck customer service line at 855-347-8371 to verify your status by providing your name and date of birth.

Another way to confirm is to look at your driver's license or state ID. If you enrolled through a participating state's ID program, your TSA PreCheck status may be printed on the card itself or linked to it. Check with your state's DMV if you are unsure whether your ID includes TSA PreCheck.

Key Takeaways

  • Log into universalenroll.dhs.gov with your enrollment email to see your active KTN and membership expiration date.
  • Search your email for a TSA PreCheck confirmation message that contains your Known Traveler Number.
  • Call TSA PreCheck customer service at 855-347-8371 with your name and date of birth to verify your status over the phone.
  • Some state driver's licenses include TSA PreCheck status printed on the card or linked to your DMV record.
  • TSA PreCheck membership lasts five years, so check your expiration date to confirm your membership is still active.

What your TSA PreCheck confirmation email contains

When you complete your TSA PreCheck enrollment appointment, TSA sends a confirmation email to the address you provided during registration. This email includes your Known Traveler Number (KTN), which is the 10-digit code you need to enter when booking flights. The email also shows your membership start date and the date your membership will expire.

If you cannot find this email, check your spam or promotions folder—confirmation emails sometimes get filtered. The email will come from an address associated with TSA or the enrollment center where you completed your appointment. If you still cannot locate it, you can request a copy by logging into your account at universalenroll.dhs.gov and viewing your membership details.

Checking your membership status online

Go to universalenroll.dhs.gov and click "Sign In" in the upper right corner. Enter the email address and password you created when you enrolled. If you forgot your password, click "Forgot Password" and follow the prompts to reset it.

Once you are logged in, your dashboard will display your membership status. You will see your KTN, the date your membership became active, and the date it expires. If the expiration date has already passed, your TSA PreCheck is no longer active. If the date is in the future, you have an active membership and can use your KTN when booking flights.

If you do not have an account on universalenroll.dhs.gov, you may have enrolled through a different program. Some people enroll through Global Entry, NEXUS, or SENTRI, which automatically include TSA PreCheck. In that case, log into the account for whichever program you enrolled in to find your KTN.

What to do if you cannot find your Known Traveler Number

Call the TSA PreCheck customer service line at 855-347-8371. Have your name, date of birth, and driver's license number ready. The representative will look up your account and provide your KTN 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.

You can also visit a TSA PreCheck enrollment center in person and ask staff to look up your information. Bring a valid government-issued ID. Enrollment centers are located at airports and other locations across the country—find one near you at universalenroll.dhs.gov by entering your zip code.

How to use your KTN when booking a flight

When you book a flight online or by phone, the airline will ask for your KTN during the reservation process. Enter all 10 digits exactly as it appears in your confirmation email or account. Some airlines call this field "Known Traveler Number," while others label it "TSA PreCheck Number" or "PreCheck ID."

If you forget to enter your KTN at booking, you can usually add it later through your airline's website or by contacting the airline directly before your flight. However, it is easier to enter it during booking so the airline can link it to your reservation from the start. When you check in at the airport, your boarding pass should show a "TSA PreCheck" indicator if your KTN was successfully added to your reservation.

Signs your TSA PreCheck has expired

TSA PreCheck membership lasts five years from the date you completed your enrollment appointment. When your membership is about to expire, TSA sends a renewal notice to your email address. If you do not renew before the expiration date, you will no longer be able to use TSA PreCheck lanes at airport security.

If you try to use your KTN after it has expired, the TSA officer at security will not recognize it as valid. You will be sent through standard security screening instead of the TSA PreCheck line. To renew, log into universalenroll.dhs.gov, pay the renewal fee, and complete a brief update appointment (which is usually shorter than the original enrollment).

Frequently Asked Questions

What is the difference between TSA PreCheck and touchless TSA PreCheck?

TSA PreCheck is the program itself—it includes expedited security screening and does not require you to remove shoes, belts, or light jackets. "Touchless" refers to technology some airports use to scan your ID and boarding pass without a TSA officer physically handling them. Both are part of the same TSA PreCheck membership; touchless is just how some airports process your documents.

Can I use someone else's KTN on my boarding pass?

No. Your KTN is tied to your identity and must match the name on your ticket and ID. Using someone else's number will cause problems at check-in and security. Each person needs their own TSA PreCheck membership.

Do I need to renew my TSA PreCheck before my flight?

If your membership has expired, you cannot use TSA PreCheck for that flight. You will go through standard security instead. Renewal takes a few days to process, so renew as soon as you see the expiration notice rather than waiting until you have a flight booked.

What if my TSA PreCheck account shows inactive or suspended?

Contact TSA PreCheck customer service at 855-347-8371. Your account may have been suspended due to a background check issue or other administrative reason. A representative can explain why and tell you what steps to take next.

Can I check my TSA PreCheck status through the TSA website instead of universalenroll.dhs.gov?

No. The official TSA PreCheck enrollment and status portal is universalenroll.dhs.gov. Other websites that claim to check your status may be scams or third-party services that charge a fee. Always use the official government site.
