Colorado: Do you need an ID to vote?
Colorado requires in-person voters to show ID, and non-photo documents such as a utility bill or bank statement count.
Accepted ID includes a Colorado driver's license or ID card, U.S. passport, Medicare or Medicaid card, birth certificate, and tribal or college IDs, plus a copy of a current utility bill, bank statement, government check, paycheck, or other government document showing name and address. Digital versions are accepted. A voter without ID can cast a provisional ballot, which counts if the clerk can confirm eligibility; voters flagged as needing ID have eight days after the election to provide a copy. Amendment 84 (Initiative 362), "Mail Ballot Voter Identification," is on the November 3, 2026 ballot.
Conditions
- Photo or non-photo ID from the list in C.R.S. 1-1-104(19.5)
- Without ID: provisional ballot
