LLNL is a national security laboratory with regulated entry. Visitors must make prior arrangements and pick up a badge at the Westgate Badge Office (located off Vasco Road in Livermore) in order to gain admittance to the Laboratory. To obtain a badge, visitors must supply Personally Identifiable Information such as a Social Security number and an approved form of identification such as a passport or driver’s license. All National Nuclear Security Administration (NNSA) facilities have implemented the Department of Homeland Security’s REAL ID Act requirements for allowable forms of identification for personnel requiring site access. Only driver’s licenses from states whose driver’s licenses are compliant with REAL ID requirements will be allowed as a primary form of identification for LLNL site access. Contact the User Office for specific details. Non-U.S. citizens must present a Permanent Resident Card or valid passport plus visa and all accompanying documentation. All visitors must wear the badge conspicuously, between their neck and waist, at all times while at LLNL.
Non-U.S. government owned computers and electronic devices are permitted in the Property Protected Areas (PPAs) and Limited Areas unless otherwise posted. Personally owned mobile devices are allowed in PPAs both outside and inside buildings. Within Limited Areas, personally owned devices are allowed to be used and stored outside and within Managed Limited Areas and can only transit through Transit/Buffer Areas. They are NOT allowed in Secure Space or Enhanced Security Areas. Please stay aware of and obey any posted signage regarding mobile devices, especially within Limited Area buildings.
- Personally owned mobile devices may connect to the LLNL-GUEST wireless network (internet access only).
- Personally owned mobile devices are not allowed to connect to LLNL-owned equipment or other networks (see "Cyber Security Policy 2026 Usage of Unclassified Computers and Electronic Devices”).
Bluetooth and wireless headsets are not permitted in Limited Area buildings. Non-U.S. government owned cameras and recording devices may be brought on site but may not be used, including the function in a cell phone or other devices, without a Controlled Items Permit issued by the LLNL Security Organization.
