In addition to Real IDs, passports, passport cards, U.S. Department of Defense IDs and DHS trusted traveler cards are considered acceptable forms of identification at TSA checkpoints. A full list of acceptable forms of identification can be found on the TSA website. The TSA says the list of acceptable IDs is subject to change without notice.

In a June 4 post, the TSA debunked long-standing rumors on social media and warned people that Costco membership cards do not qualify as a REAL ID. “We love hotdogs and rotisserie chickens as much as the next person but please stop telling people their Costco card counts as a REAL ID because it absolutely does not,” the TSA said.
