    Your PreCheck number is now saved to your profile.
    • If the name on your Delta account doesn't match what's on your driver's license or passport, you won't be able to use PreCheck. [5] If you need to update your name in your profile, fill out the Identify Verification form at https://www.delta.com/contactus/identityVerification to get things sorted out.
    • If you've already booked a flight through Delta or a travel service like Expedia or Orbitz, check your existing reservations to make sure your KTN is available. Depending on how you booked your travel, you might need to edit your reservation to add your KTN to each booking.

      • If you add your KTN too close to your travel date, you might not see the TSA PreCheck logo on your boarding pass. In this situation, you can talk to a Delta representative at the airport to make sure your TSA security check goes smoothly.
