The REAL ID Act was a piece of legislation passed in 2005 that established minimum security standards for state-issued IDs. This Act prohibits Federal agencies from accepting licenses and identification cards for domestic air travel from states that do not meet these standards. The Act regulates boarding federally regulated aircrafts, access to Federal facilities and entrance into nuclear power plants.

What You Need to Know About the REAL ID Act and Domestic Air Travel
The rules of the Act have been and will continue to be rolled out in stages. Starting January 22, 2018, the REAL ID Act will go into effect. Passengers who have driver’s licenses issued by a state that is not yet compliant or has not received an extension must show an alternate form of identification for domestic air travel. Please see the TSA’s website for a list of acceptable identification.
For more information on your state's compliance, please see the DHS REAL ID website. It will be the traveler's responsibility to confirm that they are presenting the appropriate identification at airport check-in.
The biggest hurdle will come in 2020 when travelers will need to present an actual REAL ID before boarding a commercial aircraft.
Applying for an official REAL ID will be similar to the application process for your first driver’s license.
