The star at the top right corner of your Colorado-issued driver license or identification card indicates that you are REAL ID compliant.
Passed by Congress in 2005, the REAL ID Act authorizes the U.S. Department of Homeland Security to establish national standards for state‑issued driver licenses and identification cards. In accordance with the REAL ID Act, the Colorado DMV must verify an applicant’s full legal name, identity, date of birth, and lawful presence in the United States when issuing a Colorado driver license or state identification card.
Starting October 1, 2020, every United States resident will need to present a REAL ID-compliant license/ID, or another acceptable form of identification, to access Federal facilities and board commercial aircraft. The list of other acceptable identification includes a passport; a military ID; a border ID card; a trusted traveler card, such as Global Entry; a permanent resident card; and other documents.
