12. Real ID Act FAQ (Base Access).pdf
PDF504 KBMay 19, 2026
AI Summary
The REAL ID Act, passed in 2005, establishes minimum security standards for state-issued driver's licenses and identification cards to be accepted for federal purposes such as accessing federal facilities, boarding commercial aircraft, and entering nuclear power plants. Effective May 7, 2025, non-REAL ID compliant credentials will not be accepted for identity verification at DoD installations. Acceptable forms of identification include REAL ID-compliant licenses (marked with a star), state-issued Enhanced Driver's Licenses, U.S. passports, and various other government-issued IDs. Jurisdictions can still issue non-compliant IDs, but they must clearly state their unacceptability for official purposes. Minors under 18 do not require REAL ID Act identification. Individuals without approved identification will be denied installation access and cannot be escorted. A REAL ID-compliant credential is for identification only and does not negate other visitor access requirements, including background checks. Foreign personnel require specific documentation to be considered U.S. residents for installation access, otherwise, they are processed under foreign visitor procedures. Individuals with multiple credentials must use the one reflecting their capacity for the specific visit, such as contractors using a contractor ID instead of a retiree ID.
