NASHVILLE, Tenn. (WZTV) — Pretty soon travelers will need a gold star on their IDs in order to fly.

The REAL ID Act is a federal law passed by Congress after 9/11 that establishes specific federal requirements for state-issued driver license and identity cards to be accepted for certain federal purposes, like entering a federal building or boarding a domestic flight.

Although it was passed in 2005, it will not fully go into effect until 2020.

Beginning October 1, 2020, every air traveler 18 years of age and older will need a REAL ID-compliant driver’s license or another acceptable form of ID to fly within the United States.

Tennessee will begin issuing Real ID compliant credentials beginning in July.
