REAL ID-compliant licenses are marked by a star on the top of the card.
Michigan, Vermont, Minnesota, and New York states issue REAL ID and state-issued enhanced driver’s licenses, both of which are acceptable. State-issued enhanced driver's licenses do not have a star on the top of the card.
Washington state issues enhanced driver’s licenses only. These documents will be accepted at the airport security checkpoint when the REAL ID enforcement goes into effect.
If you’re not sure, check your state driver’s licensing agency on how to obtain a REAL ID compliant card.
