Add TSA PreCheck to Delta During Booking or in Your Profile

You add your TSA PreCheck number to Delta in two places: when you book a flight, or in your frequent flyer profile before you book. The number appears on your TSA PreCheck card or in your TSA account online. Delta will use this number to show TSA PreCheck may be able to access at check-in and at security, so the TSA officer can direct you to the PreCheck lane.

If you have already booked a flight without entering your TSA PreCheck number, you can add it to that reservation up until 24 hours before departure. If you have not booked yet, adding it to your profile means it will populate automatically on every future Delta booking.

Key Takeaways

  • Your TSA PreCheck number is printed on your physical card or visible in your TSA account at tsa.gov.
  • You can add your TSA PreCheck number to your Delta SkyMiles profile so it appears on all future bookings automatically.
  • If you have already booked a flight, you can add your TSA PreCheck number to that specific reservation through Delta's website or app up to 24 hours before departure.
  • The number must match the name on your airline ticket exactly, or the TSA officer will not see your PreCheck status at security.

Find Your TSA PreCheck Number

Your TSA PreCheck number is a 10-digit code printed on the front of your physical TSA PreCheck card, usually in the upper right corner. If you do not have your card with you, you can find the number in your TSA account online.

Go to tsa.gov, click "Manage Trusted Traveler Program" in the top menu, and sign in with your username and password. Your TSA PreCheck number will appear on your account dashboard. Write it down or take a screenshot before you open Delta's website or app.

Add TSA PreCheck to Your SkyMiles Profile

Log into your Delta SkyMiles account on delta.com or the Delta app. Click on your name or profile icon in the top right corner, then select "Profile" or "My Profile." Look for a section called "Frequent Flyer Information," "Travel Information," or "Known Traveler Number."

Click the field labeled "Known Traveler Number" or "KTN" and paste or type your 10-digit TSA PreCheck number. Make sure the name on your profile matches the name on your TSA PreCheck card and your driver's license exactly — first name, last name, and any middle initials. Click "Save" or "Update."

Once you save your TSA PreCheck number to your SkyMiles profile, it will appear automatically on every Delta flight you book going forward. You do not need to enter it again for each reservation.

Add TSA PreCheck to an Existing Reservation

If you have already booked a Delta flight and want to add your TSA PreCheck number to that reservation, log into delta.com or open the Delta app. Go to "Manage My Bookings" and enter your confirmation number and last name to pull up your reservation.

Look for a section called "Passenger Information," "Trip Details," or "Frequent Flyer Information." Click the option to add or edit your Known Traveler Number. Enter your 10-digit TSA PreCheck number and save the changes. You can make this change up until 24 hours before your flight departs.

If you cannot find the field in your reservation, call Delta at 1-800-221-1212 and give the agent your confirmation number. They can add your TSA PreCheck number to the booking over the phone in a few minutes.

Make Sure Your Name Matches Exactly

The name on your Delta ticket must match the name on your TSA PreCheck card and your government ID exactly. If your SkyMiles profile has a nickname or shortened version of your name, but your TSA PreCheck card has your full legal name, the TSA system will not recognize your PreCheck status at security.

Before you travel, check that your first name, last name, and any middle initials are spelled the same way in your Delta booking, your SkyMiles profile, and your TSA PreCheck account. If they do not match, contact Delta to correct your ticket name before you go to the airport. The TSA cannot override a name mismatch, and you will be sent to the standard security line even though you have PreCheck.

What Happens at the Airport

When you check in at the airport, the Delta agent will see your TSA PreCheck number on your reservation and will print it on your boarding pass. At security, show your boarding pass and government ID to the TSA officer. If your PreCheck number is on your boarding pass and matches your ID, the officer will direct you to the TSA PreCheck lane, where you can keep your shoes, belt, and light jacket on and leave your laptop and liquids in your bag.

If your PreCheck number does not appear on your boarding pass, tell the TSA officer that you have TSA PreCheck and show them your TSA PreCheck card. They can manually verify your status, though this takes longer than having it printed on your boarding pass. This is why adding your number to Delta before you travel is worth the two minutes it takes.

Frequently Asked Questions

What if I do not see my TSA PreCheck number on my boarding pass?

Check that your name on your Delta ticket matches your TSA PreCheck card and ID exactly. If the names do not match, contact Delta to correct your ticket. If the names match and your PreCheck number is in your SkyMiles profile, contact Delta customer service to confirm the number was added to your reservation.

Can I use someone else's TSA PreCheck number on my ticket?

No. Your TSA PreCheck number is tied to your identity and your background check. The TSA officer will compare the number on your boarding pass to your government ID. If they do not match, you will not be allowed through the PreCheck lane.

Do I need to add my TSA PreCheck number every time I book a flight?

No. Once you add it to your SkyMiles profile, it will appear on every Delta flight you book automatically. You only need to add it once. If you book through a third-party website, you may need to enter it manually during that booking.

What if my TSA PreCheck expires while I have a flight booked?

You can still use the PreCheck number on your boarding pass for flights booked before your PreCheck expires. However, you cannot use PreCheck at security if your TSA PreCheck membership has expired. Renew your TSA PreCheck before your flight if your expiration date is coming up.
