Voter Registration & Information

3 Ways to Register to Vote or Update your Registration

Be sure to check the registration requirements on this page prior to registering. A registered voter in Colorado is considered a resident of Colorado for income tax and motor vehicle registration and operation.

Qualified residents may register to vote up to and including Election Day. However, in order to receive a ballot in the mail, the Boulder County Clerk & Recorder’s office must receive your voter registration no later than 8 days before the election. If you register after this time, you must visit a Vote Center in order to vote.

Attention CU students living on campus – please see our College Students page for instructions about how to enter your address so your mail ballots can find you (note: it is too late to request a ballot by mail for the 2020 General Election – see above for your options to get a ballot).

Register to vote or update your registration at www.GoVoteColorado.gov. Requires a Colorado driver’s license or CO ID. Website is available in English or Español.

Register to vote or update your registration by filling out a paper form and returning it to our office via email, mail, or fax. Click here for instructions for completing the form.

Registration/updates will take effect as of the postmark date on the form. (If postmark is not legible, the effective date is the date received by the office.)

English Form Forma Española

Register to vote or update your registration year-round at any of our three Boulder County Clerk & Recorder offices. Availability of in-person services may be limited due to COVID-19.

During election periods, eligible residents may also register to vote at any Vote Center.

Voter Eligibility Requirements

In order to vote in Colorado, you must be:

A U.S. citizen

A Colorado resident for at least 22 days before the election

Must not be serving a sentence of confinement or detention for a felony conviction (NOTE: Those on probation or parole ARE ELIGIBLE to vote.)

Age Requirements:

16-year-olds can preregister to vote

17-year-olds who will turn 18 on or before the date of the next general election are eligible to vote in a primary election.

18-year-olds can vote in any election.

ID Requirements:

While you do not need to have a Colorado ID, CO Driver’s License or other form of acceptable ID in order to register, you must produce this documentation the first time you vote. Thus, it is recommended to provide this documentation during the registration process to avoid needing to mail in a form of identification when you vote. Visit the Secretary of State list of Acceptable Forms of Identification.

Registration Timeline

There is no deadline to register to vote in Colorado. However, in order to receive a mail ballot, your registration must be received at least 8 days before the election. If you miss this deadline, you can register and get a ballot on the same day at a Vote Center.

Traveling during an election

If you will be out-of-town during an election, you can have your ballot mailed to your temporary address by updating the mailing address in your voter registration. This must be done at least 8 days before the election. Don’t forget to update your address again once you return!
