Voter information
How the primary works
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election.
Colorado utilizes a semi-closed primary system. According to Section 1-7-201 of the Colorado Revised Statutes, "An eligible unaffiliated elector, including a preregistrant who is eligible under section 1-2-101 (2)(c), is entitled to vote in the primary election of a major political party without affiliating with that political party."[2][3]
For information about which offices are nominated via primary election, see this article.
Poll times
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.[4][5]
Registration requirements
- 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.[6]
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.[6][7][8]
Automatic registration
- See also: Automatic voter registration
Colorado automatically registers eligible individuals to vote through the Department of Motor Vehicles and certain other state agencies.
Online registration
- See also: Online voter registration
Colorado has implemented an online voter registration system. Residents can register to vote by visiting this website.
Same-day registration
- See also: Same-day voter registration
Colorado allows same-day voter registration for individuals who vote in person.
Residency requirements
Colorado law requires 22 days of residency in the state before a person may vote.[7]
Verification of citizenship
Colorado does not require proof of citizenship for voter registration. An individual applying to register to vote must attest that they are a U.S. citizen under penalty of perjury.
All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment.[9] Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring verification of citizenship at the time of voter registration, whether in effect or not. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.
Verifying your registration
The site Go Vote Colorado, run by the Colorado Secretary of State office, allows residents to check their voter registration status online.
Voter ID requirements
Colorado requires voters to present non-photo identification when voting in person. If voting by mail for the first, a voter may also need to return a photocopy of his or her identification with their mail-in ballot. Click here for more information.
The following list of accepted forms of identification was current as of August 2025. Click here for the most current information, sourced directly from the Office of the Colorado Secretary of State.
| “ | The following documents are acceptable forms of identification:
Any form of identification listed above that shows your address must show a Colorado address to qualify as an acceptable form of identification. The following documents are also considered acceptable forms of identification for voting:

- Note: SB 1, signed into law on May 12, 2025, specified that tribal IDs issued by the Bureau of Indian Affairs, the Indian Health Service, or another federal agency were also valid identification.
Early and absentee 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:[12]
- 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.

According to the U.S. Department of Justice, the application "may require only the minimum amount of information necessary to prevent duplicate voter registrations and permit State officials both to determine the eligibility of the applicant to vote and to administer the voting process."
