How to Add PreCheck to Delta Before Your Flight

If you have an upcoming Delta Airlines flight, then you'll want to add your PreCheck to your Delta account so you can get that PreCheck check on your boarding pass. But how is this done?

Pre-review every time?

First, keep in mind that even if you've signed up for PreCheck, you won't get PreCheck every time you fly. PreCheck is something you have per flight, so you need to register with the airline and make sure to try to get your PreCheck pre-authorization for each flight.

In other words, you can't just assume you'll have PreCheck the same way you can use Clear or Global Entry... you have to register with the airline.

How To Add PreCheck using Delta.com

The easiest way to add your PreCheck ID to your account is at Delta.com.

• Go to the home page and log in
• Click on your name and then select "Profile"
• Click on "Secure Travel Information"
• Click on "Known Traveler Number" and then enter your number
• Press Save

The main challenge will be to find that profile page and then know one fundamental piece of information:

Your known traveler number is your PreCheck number! We might think of it as the “PreCheck Number,” but the government, and therefore the airlines, call it their KTN. This is the case because you can also use a Global Entry number, as well as a TWIC ID, NEXUS or other official identification numbers.
