The Transportation Security Administration does not want domestic flyers to try using their Costco cards in lieu of the mandated Real ID.

The TSA clarified this week that Costco membership cards are not acceptable as a newly required REAL ID at airport security checkpoints.

Since May 7, 2025, travelers have needed a REAL ID-compliant driver's license or state ID to board domestic flights. And now, TSA is putting its foot down, telling travelers that their Costco cards do not count as a valid form of ID to travel with.
