The Smithsonian National Museum of African American History and Culture has changed its admission rules: Veterans no longer need to obtain passes in advance. Instead show your ID (active duty, retired, veteran) and you can enter the museum along with two (2) guests.
Because you do not need a ticket, you cannot gift this to someone else, and the veteran must be present in order for the guests to get in.
All Veterans are included and can get ID cards from the VA, or the Veteran indicator on their Driver’s license from the local Department of Motor Vehicles (DMV). You may also show your DD214.
