Beginning Aug. 15, identification cards or driver's licenses issued by Minnesota, Missouri, Washington state or American Samoa will no longer get people past the gate at Air Force installations.

The Air Force said Aug. 4 that those identifications don't meet the security and data-collection guidelines required by the Real ID Act. That law aims to improve the reliability of state-issued identification documents, and help stop people from using fake IDs.

People with cards from those states and American Samoa can use an alternate form of identification, such as a valid passport, an employment authorization document with a photograph, or an ID card issued by other federal, state or local government agencies that includes a photo and biographic information.

Individuals without a DoD ID card will be subject to a background check. Anyone who does not have the required documentation will not be able to come on base without an escort.
