Military Identifier on Colorado Driver's License or ID
Beginning November 13, 2012, military service members and veterans may request to include a military identifier on their Colorado driver’s license and ID card. Either a valid military identification card (common access card) or a DD214 will be required.
Six branch-of-service identifiers are available: Air Force, Army, Coast Guard, Marines, National Guard or Navy. The card may only bear one military identifier and is available for an additional $15 fee per renewal.
The identifier will appear in the lower right-hand corner of the card.
At this time, the military identifier does not extend to spouses or dependents and cannot be applied to any permit.
