Where to find your TSA PreCheck number

Your TSA PreCheck number is printed on the back of your trusted traveler card, in the bottom right corner. It is a nine-digit number that starts with the letters "TSA" followed by six numbers. If you have your physical card, you can read it directly from there.

If you do not have your card in front of you, you can retrieve your number through the TSA's official website or by contacting the TSA directly. The fastest method is logging into your account on the TSA PreCheck enrollment website, where your number appears in your profile.

Logging into your TSA PreCheck account online

Go to the official TSA PreCheck enrollment website at universalenroll.dhs.gov. Click "Sign In" in the upper right corner and enter the email address and password you used when you enrolled.

Once you are logged in, your dashboard will display your account information. Your TSA PreCheck number appears in the "Known Traveler Number (KTN)" field. Write it down or take a screenshot for your records.

If you have forgotten your password, click "Forgot Password" on the login page and follow the steps to reset it using your email address. You will receive a link to create a new password within a few minutes.

Calling TSA PreCheck customer service

If you cannot access your online account, you can call the TSA PreCheck customer service line at 1-855-347-8371. The line is open 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.

Have your driver's license or passport number ready when you call. The representative will verify your identity and provide your TSA PreCheck number over the phone. They can also help you reset your online account password if needed.

What to do if your card is lost or damaged

If your physical card is lost or damaged, you can still use your TSA PreCheck number when you book flights and check in at the airport. Your number remains active in the TSA system regardless of the card's condition.

To request a replacement card, log into your account on the enrollment website and look for the option to order a new card. There is typically a replacement fee, which varies by program. You can also call customer service to request a replacement over the phone.

Using your TSA PreCheck number when you travel

When you book a flight, enter your TSA PreCheck number in the "Known Traveler Number" field during checkout. This field is usually found in the passenger information section of the airline's website or booking system.

At the airport, your TSA PreCheck status will appear on your boarding pass if the number was entered correctly. Look for a "TSA PreCheck" indicator or a "✓" symbol on your pass. Present your boarding pass and ID at security, and you will be directed to the TSA PreCheck lane.

If your boarding pass does not show TSA PreCheck, inform the TSA officer at security. They can manually look up your number in the system, though this may take longer than having it printed on your pass.

Troubleshooting common issues

If you cannot find your number online or by phone, check that you are using the correct email address and password. Many people enroll with a work email and later forget which address they used. Try logging in with any email addresses you have used in the past five years.

If your account shows no active TSA PreCheck membership, your enrollment may have expired. TSA PreCheck is valid for five years from the date of approval. You can check your membership status in your online account under "My Membership." If it has expired, you will need to enroll again to receive a new number.

If you enrolled through a third-party enrollment provider rather than directly through the TSA, you may need to contact that provider to retrieve your number. Common providers include Clear, Costco, and American Express, depending on how you enrolled.

Frequently Asked Questions

Can I use my TSA PreCheck number if I do not have my physical card?

Yes. Your TSA PreCheck number is what matters at security and when booking flights, not the physical card. As long as your number is entered correctly on your boarding pass, you can use TSA PreCheck without the card present.

What if I entered my TSA PreCheck number wrong when booking my flight?

Contact your airline before your flight to update your reservation with the correct number. Most airlines allow you to change your known traveler number online through your booking or by calling their customer service. The change usually takes effect within a few hours.

Is my TSA PreCheck number the same as my confirmation number?

No. Your confirmation number is a separate code the TSA sends you when you complete your enrollment appointment. Your TSA PreCheck number is the nine-digit code that appears on your card and in your account. You need the TSA PreCheck number for travel.

How long does it take to receive my TSA PreCheck number after I enroll?

You typically receive your number within three to five business days after your in-person appointment is completed. You can check your account status online to see when your membership is approved. Some people receive their number the same day as their appointment.

Can I share my TSA PreCheck number with family members?

No. Your TSA PreCheck number is tied to your identity and can only be used by you. Each family member who wants TSA PreCheck benefits must enroll separately and receive their own number.
