Updating your DEERS/ID Card requires that you make an appointment on the DOD ID Card Online Office website. To obtain a Visitor's Badge, you will need a valid government-issued picture identification, such as a driver's license, state-issued ID, or passport. Visitor's Badges may be issued for up to six months. When accessing Fort Walker, visitors must present a Visitor Badge and a valid government-issued picture identification card at the access control point.
