Questions & Answers / Clarifications

This document provides Frequently Asked Questions (FAQs) regarding the REAL ID Act and its implications for accessing DoD installations, specifically MHAFB. It clarifies identification requirements for personnel and visitors.

• REAL ID Act Compliance Deadline: As of May 7, 2025, non-REAL ID Act compliant state-issued driver's licenses or identification credentials will no longer be accepted for identity proofing at DoD installations.
• Accepted Identification: Only REAL ID Act compliant driver's licenses/identification credentials (marked with a star) or other approved forms of identification will be accepted for identity proofing.
• Alternative Forms of ID: Several alternative forms of identification are accepted, including State-issued Enhanced Driver's Licenses, U.S. Passports, U.S. Passport Cards, DHS trusted traveler cards, U.S. Department of Defense IDs, Permanent Resident Cards, federally recognized Tribal Nation IDs, HSPD-12 PIV cards, and foreign government-issued passports.
• Non-Compliant IDs: Jurisdictions can still issue non-compliant licenses, but they must clearly state they are not acceptable for official purposes.
• Enhanced Driver's Licenses (EDL/EID): These are accepted as border-crossing documents and are an acceptable alternative to REAL ID.
• Minors: Identification is not required for children under 18; the sponsor will need acceptable identification.
• Installation Access: A REAL ID Act compliant ID is for identification purposes only; all visitors must still meet other access requirements and background checks.
• Proof of US Residency: REAL ID compliant IDs are not proof of US residency. Only specific documents like Permanent Resident Cards or certain foreign passports with stamps/visas are considered proof of US residency for installation access.
• Multiple Credentials: Individuals with multiple credentials must use the one that most accurately depicts their capacity for the specific visit (e.g., a contractor must use contractor identification, not retiree ID).

This FAQ directly impacts any opportunity requiring access to DoD installations, as it specifies the required forms of identification for personnel and visitors, effective May 7, 2025. Bidders should ensure their personnel and any visitors associated with the contract meet these identification requirements.
