I’ve heard that if I use my DOD ID number I can gain access to TSA Pre-Check – is that true?

Yes, members of the U.S. Armed Forces, including National Guard and Reserves, can gain membership in the TSA Pre-Check program by using their DOD ID number as a Known Traveler Number. To do this simply enter your 10-digit DOD ID number in the Known Traveler Number box of your Travel-On profile. This box is located at the bottom of the Travel Preferences page. Once entered, this number will be transmitted to the airlines every time you make a reservation through Travel-On. It is not necessary to be in uniform or to show your CAC card at the TSA checkpoint. If selected to access the Pre-Check lanes, your boarding pass will contain the TSA Pre-Check logo. It is important to remember that membership in the TSA Pre-Check program does not guarantee that you will be selected to receive the benefits on every trip.
