You do not need a REAL ID to vote in Colorado.

Your driver’s license or state ID card will show a star in the upper corner if it meets REAL ID requirements under federal law.

Colorado only issues REAL ID-compliant driver’s licenses and state IDs.

If you need to renew your state photo ID or driver’s license (or apply for a new one) you must go through the REAL ID process.
