You will need a government-issued photo ID (e.g., passport or driver’s license) when you check into the Visitors Center at the entrance of NIST and if bringing a vehicle onto the NIST campus, a vehicle registration card.
PLEASE NOTE: Effective July 21, 2014, under the REAL ID Act of 2005 (https://www.dhs.gov/real-id/real-id-frequently-asked-questions), agencies, including NIST, can only accept a state-issued driver’s license or identification card for access to federal facilities if issued by states that are REAL ID compliant or have an extension. NIST currently accepts other forms of federally issued identification in lieu of a state-issued driver’s license, such as a valid passport, passport card, DOD’s Common Access Card (CAC), Veterans ID, Federal Agency HSPD-12 IDs, Military Dependents ID, Transportation Workers Identification Credential (TWIC), and TSA Trusted Traveler ID. See Visitor Information for the latest information.
