Travelers who are headed to airports and hoping to use their Costco membership cards in place of Real IDs are out of luck. Travelers need a Real ID — or other acceptable form of identification — for domestic flights and for accessing federal facilities as of May 7.

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.
