Voter registration[edit]

Eligibility and registration details[edit]

Check your voter registration status here.

In Colorado, an individual can pre-register to vote if they are at least 15 years old. Voters must be at least 18 years old to vote in any election. A voter must be a citizen of the United States and have established residence in Colorado to vote.^[1]

Colorado voters can register to vote through Election Day. However, in order to automatically receive a absentee/mail-in ballot, a voter must register online, through the mail, at a voter registration agency, or driver's license examination facility at least eight days prior to Election Day. A voter that registers through a voter registration drive must submit their application no later than 22 days before the election to automatically receive an absentee/mail-in ballot. A voter can register online or submit a form in person or by fax, email, or mail.^[1]^[2]

In-person voting[edit]

Poll times[edit]

In Colorado, polls are open from 7:00 a.m. to 7:00 p.m. local time for those who choose to vote in person rather than by mail. An individual who is in line at the time polls close must be allowed to vote.^[3]^[4]

Voter identification[edit]

Early voting[edit]

See also: Early voting

Colorado uses a vote-by-mail system exclusively, so there is no need for explicit absentee or early voting procedures, except for those who cannot or do not wish to vote by mail. County clerks and recorders automatically send mail ballots to every elector in active status, starting 18 to 22 days before the election. The last day on which a county clerk can mail a ballot to a voter is eight days before the election. However, since electors can register to vote until the polls close at 7 p.m. on Election Day, there are always some voters that cannot vote by mail ballot. Therefore, Colorado law requires county clerks to open and operate polling locations called Voter Service and Polling Centers (VSPCs) starting 15 days before the election through Election Day, excluding Sundays. For primary and November coordinated elections, VSPCs must be open starting 8 days before the election. Eligible voters can visit any VSPC in their county of residence to do any of the following:^[7]^[8]

Void their mail ballot to vote in person,
Register to vote,
Update an existing voter registration record,
Obtain a mail ballot "over-the-counter," or
Vote in person on paper ballots or accessible voting devices.

Early voting permits citizens to cast ballots in person at a polling place prior to an election. In states that permit no-excuse early voting, a voter does not have to provide an excuse for being unable to vote on Election Day. States that allow voters to cast no-excuse absentee/mail-in ballots in person are counted as no-excuse early voting states.

As of February 2024, 47 states and the District of Columbia permitted no-excuse early voting.

Mail-in voting[edit]

See also: Absentee/mail-in voting and All-mail voting

Colorado conducts what are commonly referred to as all-mail elections. In Colorado, voting is conducted primarily, although not necessarily exclusively, by mail. Election officials automatically distribute mail-in ballots to active electors starting 18 to 22 days before an election. Colorado law requires county clerks to operate polling locations (Voter Service and Polling Centers, or VSPCs) starting 15 days before an election and continuing through Election Day, excluding Sundays. At these locations, eligible voters can do any of the following:^[9]

void their mail-in ballots to vote in person,
register to vote,
update existing voter registration records,
obtain mail-in ballots, or
vote in person via paper ballots or accessible voting devices.

Voting rules for people convicted of a felony[edit]

See also: Voting rights for people convicted of a felony

In Colorado, people convicted of a felony are disenfranchised so long as they are incarcerated; those on parole, probation, or with unpaid restitution and fines regain their right to vote.^[10]

Voting rights for people convicted of a felony vary from state to state. In the majority of states, people convicted of a felony cannot vote while they are incarcerated but may regain the right to vote upon release from prison or at some point thereafter.^[11]
