Beginning in October of 2020, you won’t be be able to fly unless you have a REAL ID. After the terror attacks on the U.S. in 9/2001, Congress enacted a law that requires specific types of identification for people to access federal facilities, fly on commercial aircraft that is federally regulated, and to enter nuclear power plants.
In most states, when you present specific types of documentation at the time you obtain or renew your driver’s license, it will be marked with a star as REAL ID-compliant.
