At a glance
Many people are registered automatically when they deal with the DMV or certain state agencies. You can register and vote on the same day, including Election Day.
Show one of many photo or non-photo IDs (e.g. utility bill, bank statement); without it, vote a provisional ballot that counts once eligibility is verified. No ID? Ask your election office whether it offers a free one for voting. First-time voters who registered by mail may need to show ID under federal law.
Ballot mailed automatically to every registered voter; no request needed Return deadline: received by 7 p.m. Nov 3 (Election Day).
Voter service and polling centers open Oct 19 - Nov 3 (15 days before)
Only people serving a felony sentence in prison lose the vote; rights return automatically on release, including on parole.

Where the road gets harder
Every rule is a cost, and it doesn't fall on everyone the same. A deadline, a document or a trip to an office is easy for some people and a real obstacle for others: people who work hourly jobs, move often, live far from an office, don't drive, or have a disability. Here is what that looks like in Colorado.
- Mail ballots have to arrive by Election Day; a postmark isn't enough. A ballot mailed in the last days can arrive too late and won't count, so return it in person if it's close.
