Colorado

Colorado is a vote-by-mail state. Your ballot will automatically be sent to the address where you are registered to vote.

You do not need ID to vote by mail in Colorado (except for some first-time voters). 

If you vote in person, you will be asked to show an ID or sign a form to confirm your identity.

The Elections Division is reviewing whether you can show an acceptable ID on an electronic device, although the general practice is that you can provide a picture of your driver’s license. To be safe, bring your physical ID.

If you do not present an acceptable ID at the polling place, you must complete a provisional ballot affidavit.

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

REAL ID is a set of national security standards for states to follow when they issue driver’s licenses and state ID cards. Your ID will show a star if it meets REAL ID standards.

Applying for a REAL ID requires you to appear in person with a variety of documents to prove your identity.

Colorado now issues only REAL ID-compliant driver’s licenses and state ID cards. If you need to renew your Colorado license or ID (or apply for a new one), you must go through the REAL ID process. Visit the Colorado DMV wesbite to learn more.

Colorado ID Requirements for Voting By Mail

Colorado automatically sends mail ballots to all registered voters. There is no need to request your ballot and no excuse is required to vote by mail.

You will be notified if you need to provide ID with your ballot.

Note that the signature on your ballot must match your signature on file with the state.

Frequently Asked Questions

If your mail ballot is rejected due to a missing or unmatching signature, or failure to enclose a photocopy of an acceptable form of ID with your ballot, if required, you may use Colorado’s TXT2Cure system to resolve those issues and ensure your ballot is counted.

If your signature on your ballot’s identification envelope does not match your signature on file with the state, you will be notified via a letter sent to the address in your registration record. You will also be notified by email, if available. You will be sent notification within three days after the signature deficiency has been confirmed, but no later than two days after Election Day.

A confirmation form accompanying your notification letter must be returned to the county clerk and recorder within eight days after Election Day for your ballot to count. Find your local county clerk and recorder office.
