The REAL ID program serves to create more secure issuance of identification. Beginning on October 1, 2020, you will need to show a REAL ID-compliant license, valid passport or
other acceptable form of federal identification to board a plane or enter a federal building. A standard license will no longer be an acceptable form of federal identification. However, enhanced driver’s licenses (EDLs) are acceptable, but the only states that offer them are Michigan, Minnesota, New York and Washington.
To obtain a REAL ID, you will need to apply in person at your state motor vehicle department and provide documentation of your age, identity, Social Security number and address.
In most states, you have an option of obtaining a traditional driver’s license or REAL ID.
Visit your state’s website for more information about regulations and requirements.
Children under 18 do not need to show identification for domestic flights.
