Colorado

Colorado's primary election is scheduled for June 30, 2026. All active registered voters will receive a mail ballot approximately three weeks before the election.

To vote in Colorado, you must be a U.S. citizen, a Colorado resident for at least 22 days before the election, and at least 16 years old (though you must be 18 by Election Day to cast a ballot). Individuals with felony convictions who are currently incarcerated are not eligible to vote, but those on parole are eligible.

You can register to vote online at GoVoteColorado.gov, by mail using a voter registration form, or in person at your county clerk's office or a Voter Service and Polling Center. Colorado also offers Election Day registration, allowing eligible residents to register and vote on the same day during early voting and on Election Day itself.

Yes. Colorado automatically mails ballots to all active registered voters for every election. Ballots are typically mailed 18-22 days before Election Day. You can return your ballot by mail with no postage required, drop it in a secure 24-hour drop box, or deliver it in person to a Voter Service and Polling Center.

Most Colorado voters do not need to show ID. However, first-time voters who registered by mail without providing a copy of identification must show ID the first time they vote. Acceptable IDs include a Colorado driver's license, a utility bill, bank statement, paycheck, or government document showing your name and address. When voting by mail, all voters verify their identity through signature matching rather than presenting ID.

The general election is Tuesday, November 3, 2026. Polls and Voter Service and Polling Centers are open from 7:00 AM to 7:00 PM. If you're in line by 7:00 PM, you will be able to vote. Mail ballots must be received by 7:00 PM on Election Day—postmarks do not count.
