TSA Precheck Program For DoD Personnel

TSA Precheck is a voluntary, expedited security screening process offered at over 180 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. The program is open at no cost to DoD civilians and Service members (including Reservists, National Guardsmen, members of the 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).

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.

  2. Opt-In to the program (applies to DoD civilians only). Civilians need to log in to the MilConnect website (, click on the "My Profile" tab and then select "Update and View My Profile.". Next, click on the "CIV" tab. In the Personnel Status information box, click on the "TSA Precheck Program" checkbox and scroll to the bottom of the page and click "submit". Service members already are eligible and do not need to opt in to the program.

Additional Information

Eligible Service members do not need to be on official travel or in uniform to take advantage of TSA Precheck. Family members ages 12 and under traveling with an eligible Service member or DoD civilian can process through expedited screening as well. However, family members 13 and older must go through regular security lines or may apply for TSA Trusted Traveler program (for a fee).

Boarding passes must have TSA Precheck eligibility information embedded in the barcode when scanned on the boarding pass scanner system in order to use the TSA Precheck security lanes. Your DoD ID number does not display on the boarding pass. Please be aware that not all airlines print a TSA Precheck approved indicator on the boarding pass. However, if travelers used their DoD ID number as the “Known Traveler Number,” they may proceed to a dedicated Precheck security lane to check eligibility.
