15 | P a g e 25 June 2025

DoD Manual 5200.08 Vol 3, Physical Security Program: Access: to DoD Installations.

Federal installations, including Davis-Monthan AFB, will no longer accept non-marked state-issued identification cards after May 6, 2025. As mandated by the Department of Homeland Security (DHS), state-issued licenses and identification cards must include a REAL ID-compliant marking– star markings, “Enhanced” verbiage, etc.—indicating adherence to federal standards. Enhanced Driver’s Licenses (EDLs) issued by Washington, Michigan, Minnesota, New York and Vermont are also acceptable for federal purposes. Although most EDLs do not contain the REAL ID star marking, they meet DHS criteria for access.

To obtain a REAL ID, individuals must visit their state’s driver licensing agency website for documentation requirements. At a minimum, applicants must provide proof of full legal name, date of birth, Social Security number, two proofs of address and lawful status. States may impose additional requirements. Minors under 18 years of age are not required to present REAL ID-compliant credentials for travel or base access, but their accompanying adult must be compliant.

Individuals issued a “LIMITED-TERM” REAL ID—commonly non-citizens with documentation such as a Permanent Resident Card, visa, or employment authorization—must present the same documentation when requesting access to DMAFB.

Common REAL ID-compliant credentials include U.S. passports, permanent resident cards and other identification approved under DODM5200.08v3. Current Defense Biometric Identification System (DBIDS) badges are not impacted by this change. However, new or replacement DBIDS badges will only be issued upon presentation of REAL ID-compliant credentials. When screening visitors for DBIDS Contractor Badges and EAL sponsorship visitation requests, it is the direct responsibility of the DoD-affiliated sponsor to verify that the personnel they are requesting badging or visitation for are REAL ID compliant.

For DBIDS contractors, Visitor Control Center badging personnel will confirm contractors’ REAL ID compliance when they come to receive their DBIDS badge. Security Forces personnel will verify visitors’ driver’s licenses and identification cards to ensure REAL ID compliance is met. Non-compliance will result in immediate denial to the installation until REAL ID compliance is met.

Security Forces entry controllers will verify REAL ID compliance of visitors when verifying their credentials with Entry Authorization Lists. Non-compliance will result in immediate denial to the installation until REAL ID compliance is met.
