Your military ID card is a REAL ID, as listed on the TSA website
Some TSA locations however, fail to accept them for travel because of the INDEF expiration date. The TSA's Credential Authentication Technology (CAT) system https://www.tsa.gov/travel/security-screening/credential-authentication-technology fails to read the barcode with INDEF due to INDEF not being an actual date, which the CAT system expects. DMDC Fixed this. As of late 2025, DMDC modified the DEERS/RAPIDS application to add an actual date to the barcode so it will scan at TSA. Read more about this on the DEERS ID Process page.
It is always recommended to carry another REAL ID such as a drivers license), your Passport or Passport Card. Read more on our Passport page.
