TSA PreCheck®

Free to DoD civilians and Service members, TSA PreCheck is a voluntary, expedited security screening process offered at select domestic airports [] that allows participants to keep on their shoes, belt, and light jacket, and leave laptops and 3-1-1 compliant liquids in their carry-on bags.

In order to use dedicated TSA Precheck security lanes, participants must enter their DoD ID number as the “Known Traveler Number” when making official travel or leisure airline reservations.


The program is offered to DoD civilians and Service members (including Reservists, National Guardsmen, the U.S. Coast Guard, and students at the U.S. Military Academy, the U.S. Naval Academy, the U.S. Coast Guard Academy, and the U.S. Air Force Academy).

At this time, Non-Appropriated Fund (NAF) employees, retirees, veterans, NOAA Commissioned Officer Corps, and U.S. Public Health Service Commissioned Corps are not eligible to participate in the free program.

Family members ages 12 and under may accompany participating Service members or DoD civilians through the TSA PreCheck line. Family members 13 and older must go through regular security lines or be separately enrolled in a Trusted Traveler Program [].

DoD Service members are enrolled in the program automatically; Just add your DoD ID number to your defense travel system profile and leisure travel reservations or personal frequent flyer program profiles. Service members do not need to be in uniform to take advantage of TSA PreCheck.

DoD civilian participation in the program is voluntary. Enrollment requires a one-time opt-in.

One-time Civilian Opt-in Process

Civilians may opt-in to the program by visiting the DoD ID Card Office Online and following these steps:

  1. In the "My Profile" box (right side of screen), click CONTINUE.
  2. On the next screen, click the tab for CAC and login using your CAC certificate.
  3. On the Self-service Consent to Monitor page, click OK.
  4. On the next screen, click the CIV tab.
  5. Look for the Personnel section, and check the box for TSA PreCheck Program.
  6. Scroll to the bottom of the page and click SUBMIT to save your changes.

Ensure Reservation Status

Once you have TSA PreCheck, you'll still need to add your DoD ID Number to your reservations to use the expedited security lanes.

  1. Locate your 10-digit DoD ID Number.

    This number can usually be found on the back of your Common Access Card. If it's not listed there, log into DoD ID Card Office Online [] and locate it under the "My Profile" section.

  2. Save your DoD ID Number to your profiles.

    To ensure your DoD ID Number is automatically applied to future reservations, save it as your Known Traveler Number in your profile on DTS and MyTravel. To use PreCheck on leisure travel, add the number to personal reservations and frequent flyer program profiles.

  3. Check that your DoD ID Number appears in the Known Traveler Number field of your reservations.

    If you've saved your DoD ID Number to your travel system profile, it should automatically populate. If you haven't, you'll need to add it manually or provide it to your Travel Management Company.

  4. Check your boarding pass for the TSA PreCheck logo.

    Your boarding pass should show a TSA PreCheck approved indicator. Your DoD ID Number will not display.
