Colorado allows for same-day voter registration, meaning that you are able to register to vote up until Election Day.

Check Registration Status

In order to register to vote, you must be a U.S. citizen and have residency in Colorado at least 22 days prior to Election Day.

  • You can register to vote if you are at least 16 years old, but can only vote if you will be 18 by Election Day.
  • In Colorado, those convicted of a felony are disenfranchised only as long as they are incarcerated; those on parole, probation, or with unpaid restitution and fines regain their right to vote.
  • Colorado’s Secretary of State’s website states: “For the purposes of registering to vote and voting, no person may gain residence because of their presence in Colorado. Likewise, persons may not lose residence because of their absence while in military service or while a student at any institution of higher education.” Out-of-state students attending college in Colorado may, therefore, experience difficulties claiming Colorado residency.


Colorado has same-day voter registration, meaning that you are able to register to vote up until the date of the General Election (November 3, 2020).

Colorado already uses a mostly vote-by-mail system, so voters are encouraged to register before October 26, 2020, in order to vote-by-mail. Voting by mail is important to reduce your risk of exposure to COVID-19.

Vote-By-Mail Practices

Colorado uses a vote-by-mail system except for those who cannot or do not wish to vote by mail. All eligible voters will receive a mail ballot as long as they are registered by October 26.

  • To receive a ballot by mail you can register by October 26 online, through the mail, at a voter registration agency, or at a local driver’s license examination facility. Or, you may submit an application through a voter registration drive no later than 22 days before Election Day.
  • Completed ballots must be received by the County Clerk and Recorder no later than 7pm on Election Day. Postmarks do not count.
  • If you are voting by mail for the first time, you may need to provide a photocopy of a form of ID when you return your ballot.
  • Further by-mail voting information for Colorado is listed here.
