When can I vote early in Colorado?
Early voting runs Oct 19, 2026 through Nov 3, 2026. Hours and sites are set locally.
Is it too late to register in Colorado?
Register online by Oct 26, 2026 if you can. Mailed forms should be postmarked by Oct 26, 2026. Register in person by Nov 3, 2026. After Oct 26, register in person at any Voter Service and Polling Center in your county and vote there, through 7 PM Election Day. You won't be mailed a ballot.
Do I need ID to vote in Colorado?
You need ID to vote in person, but it doesn't have to have a photo: a Colorado license, passport, a Colorado college photo student ID, or a utility bill or bank statement from the last 60 days all work. First-time mail voters may need to include a copy of ID.
Can college students vote where they go to school in Colorado?
It's your call. Colorado students at school out of state can stay registered at home and vote by mail. Students living in Colorado can register at their Colorado school address if that's where they live, since being a student doesn't make you gain or lose residence. A Colorado college photo student ID counts as voter ID.
Do I need to request a mail ballot in Colorado?
No request needed; ballots are mailed to all active voters. Register or update by Oct 26 to be mailed one.
When does my mail ballot have to arrive in Colorado?
Your ballot must be received by Nov 3, 2026 at 7:00 AM. Postmarks don't count.
Can I track my ballot in Colorado?
Use Colorado's ballot tracker to see when your ballot was sent, received, and accepted.
Can I take a photo of my ballot in Colorado?
Legal. Colorado repealed its ban in 2017 (HB 1014); C.R.S. 1-13-712 treats sharing an image of your own ballot as consent.
Can I vote with a felony record in Colorado?
You can't vote while incarcerated for a felony. Once you're out, including on parole, you can vote, but you may need to re-register.
