How Vote By Mail Works in Colorado
Colorado is a vote-by-mail state, meaning that all registered voters receive a ballot in the mail. The deadline to register to vote and receive a ballot in the mail is 8 days before Election Day.
After you complete your ballot, be sure to return it ASAP!
- Return in person by Election Day at 7 p.m. You can return to any county drop boxes, Voter Service and Polling Center, and your county election office.
- Or stamp and return your ballot by mail - your ballot must be mailed so that it is received by Election Day. We recommend mailing your ballot at least two weeks before as the post office is not always reliable. The best intentions or postmark will not matter if your ballot is received after Election Day - your ballot will not count.
