Campus Access and Security
The National Institutes of Health, like all Federal Government facilities, has instituted security measures to ensure the safety of our patients, employees, guests and facilities. Please visit the Department of Homeland Security National Terrorism Advisory System (NTAS) site to learn more about any current terrorist threat alerts for government and public entities that may impact NIH security.
All visitors must enter through the NIH Gateway Center. You will be asked to submit to a vehicle or personal inspection. Visitors over 15 years of age must provide a form of government-issued ID such as a driver's license or passport. Visitors under 16 years of age must be accompanied by an adult.
Please be aware: Federal law prohibits the following items on Federal property: firearms, explosives, archery equipment, dangerous weapons, knives with blades over 2½ inches, alcoholic beverages, open containers of alcohol and marijuana (cannabis).
Visitors are encouraged to use public transportation such as the Metrorail subway system which has a convenient stop (Medical Center) on the NIH campus. Visit the "Metro" site for information on fares and schedules.

NIH Gateway Center
Visitors will be required to show one (1) form of identification (a government-issued photo ID-driver's license, passport, green card, etc.) and to state the purpose of their visit.
The NIH Gateway Center is located adjacent to the Medical Center Metro Station at the South Drive entrance to campus from Rockville Pike / Wisconsin Avenue (Route 355). It combines visitor parking, non-commercial vehicle inspection and visitor ID processing, all in one location. The NIH will process all visitors in vehicles or as pedestrians.
Patients and patient visitors should continue to enter campus at the West Drive/Cedar Lane entrance during the hours of 6am–10pm, 7 days a week.
***REAL ID Enforcement Delayed Until May 23, 2023 – Extension Does Not Apply to Commercial Vehicle Operators***
As of October 1, 2020, the National Institutes of Health (NIH) will no longer accept identification credentials that fail to meet the minimum requirements and issuance standards for federal recognition per the REAL ID Act of 2005. The Act establishes minimum security standards for state-issued driver’s licenses and identification cards and prohibits federal agencies, such as NIH, from accepting for official purposes licenses and identification cards that do not meet these standards.
Under the REAL ID ACT, NIH may only accept state-issued driver’s licenses and identification cards that meet the standards required by the ACT to access our facilities. Enhanced Driver’s Licenses (EDL) issued by Michigan, Minnesota, New York, Vermont, and Washington are considered acceptable alternatives to REAL ID-compliant cards and will also be accepted for official REAL ID purposes. Most EDLs do not contain the star marking and this is acceptable. The EDLs do however state they are enhanced driver’s licenses and have an American flag either overlapping the picture or at the bottom right hand corner.
Individuals who come to the NIH’s Clinical Center for inpatient or outpatient services are not subject to the REAL ID Act of 2005.
Approved Forms of ID Required to Enter NIH Facilities as of October 1, 2020:
- REAL ID Driver’s License or State Identification Card or Enhanced Driver’s License
- Passport or Passport Card
- HSPD-12 PIV or CAC Card
- Permanent Resident Card
- Federally Recognized, Tribal-Issued Photo ID
- Canadian Provincial Driver's License or Indian and Northern Affairs Canada Card
- USCIS Employment Authorization Card (I-766)
- Other Less Common Documents (e.g. Merchant Mariner Credential)

The Gateway complex also includes MLP-11, a 342-space, multi-level underground parking garage. This visitor-only lot is the primary visitor parking for the NIH main campus. We strongly encourage all visitors to park in this garage as there will be limited visitor parking on campus, other than for patients and visitors to the Clinical Center. Vehicles parking in MLP-11 are outside of the perimeter security and will not go through vehicle inspection, reducing the amount of time it takes to get on campus.
MLP-11 Hours of Operation:
When MLP-11 is closed, visitors can park in lots on the NIH main campus.
Vehicles left in the MLP-11 parking garage after 11pm on weekdays or during weekends are subject to ticketing and towing.
Commercial vehicle deliveries must undergo security screening at the Commercial Vehicle Inspection Facility (CVIF). It is located on Rockville Pike between North Drive and Wilson Drive and is open 24 hours a day, 7 days a week (inbound traffic only).
Commercial food and catering delivery vehicles should enter via the CVIF. Food deliveries made in private vehicles without commercial signage may use either the CVIF or the Gateway Center.
Vendors and contractors with frequent official business at NIH can be issued special temporary IDs. You must provide an original letter on company letter head or a memo from your NIH Project Officer justifying your need for a temporary ID. The letter/memo must contain your full name and date of birth and must be presented in person with a valid photo ID at The NIH Guard Office Operations Branch (part of the NIH Police) located in 31/B4BE09 (Phone: 301-435-5095).

Due to the checking of IDs at the perimeter, employees and visitors will not be required to show their ID again to gain access to the majority of buildings on the NIH Bethesda campus during the normal business day. Employees and visitors should continue to wear their identification prominently at all times while on campus.
Guards will remain at certain buildings to address specific program requirements such as sensitive research and safety concerns. At building entrances where guards are posted:
- Employees must show a DHHS-issued photo ID (for example, your NIH-issued ID badge)
- Visitors may be required to log in, wear a visitors pass and have an employee escort them through the building.
- Visitors may be required to pass through a metal detector and have bags, backpacks or purses inspected or x-rayed as they enter buildings.
- Security staff will be looking for and confiscating any suspicious or potentially dangerous materials. U.S. Code prohibits bringing any dangerous weapons onto Federal property, including anything with a blade longer than 2 ½ inches. Meeting participants may want to leave extra bags or personal materials at their hotel to minimize the time needed for inspection
After-hours building access will require the use of an employee ID at electronic access card readers at building entrances and certain internal areas. Similar, appropriate security adjustments will be made at off-campus facilities. Employees are encouraged to be vigilant and report anyone using unauthorized entrances or suspicious activity to the NIH Police at 301-496-5685.
Information regarding emergency planning and preparedness at the NIH is available in the NIH Emergency Preparedness Handbook.
