Visitor Information

Note to all NIST Visitors*:
The Gaithersburg, Md., and Boulder, Colo., campuses of NIST are closed to the general public at this time. Official visitors must present photo identification* and vehicle registration information upon arrival. Visitors can access the Gaithersburg campus from the main gate at W. Diamond Ave. and Bureau Drive only. Visitors must wear a visitor badge at all times while on the NIST campus.

If you plan to attend a NIST conference, please note that all attendees must be pre-registered. Photo identification* and vehicle registration information must be presented at the main gate to be admitted to the conference. International attendees are required to present a passport. Attendees must wear their conference badge at all times while on the campus. For information on registering for specific conferences, please visit our conference page.

Site Access for Visitors with Disabilities

NIST visitors and conference attendees with disabilities are able to remain in their vehicles for the clearance process rather than having to exit their vehicles. In Gaithersburg, these visitors should access the site using Gate F. Gate F is located on Muddy Branch Dr. between West Side Drive and Palmspring Dr. In Boulder, access will be via the main front gate and visitors should coordinate with their NIST sponsor.

*UPDATE: New Visitor Access Requirements

Effective July 21, 2014, under the REAL ID Act of 2005, federal 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.

See map below for details. You can find additional details on the DHS web site.
