1.5 CONTRACTOR ACCESS AND USE OF PREMISES
DBIDS has gone live at MCAS Cherry Point. In order to reduce wait time when exchanging your RapidGate credential, it is highly recommended each applicant pre-register at https://dbids-global.dmdc.mil/enroll#!/
Non-DoD cardholding visitors to Marine Corps Installations with a driver's license or ID issued by a state that is not compliant with the Real ID Act of 2005 will now need to provide an alternate form of acceptable identification to gain entry, or be escorted by an authorized patron of the air station.
https://dbids-global.dmdc.mil/enroll%23!/
North Carolina now issues REAL ID compliant driver’s licenses, but many drivers have yet to be issued the new license.
Drivers may get a North Carolina REAL ID driver's license at any NCDMV driver's license office.
The Act established minimum security standards for license issuance and production and prohibits Federal agencies from accepting driver's licenses and identification cards from states not meeting the Act's minimum standards.
