military voters

Colorado makes it easy for our residents in uniform to vote in Colorado elections.  Military personnel serving outside of the state can receive and return their ballots by either mail, fax, or email.

Active military voters can update their Uniformed and Overseas Citizens Absentee Voting Act (UOCAVA) status online at GoVoteColorado.gov.


student voters

Did you know ...? Colorado allows residents to pre-register to vote starting at age 16. Pre-registered voters can't vote until age 18.

In order to receive their mail ballot, college students who have changed their address since registering to vote, will need to update their mailing address at GoVoteColorado.gov. This includes college students attending college out of state, but have maintained Colorado as their residence. (You may only vote in one state.)

voters without a fixed permanent residence

Voters without a fixed permanent residence may provide a physical location as an address if they intend that location to be their "home base." For example, a full-time RVer may use a campground as a home base for registration purposes.

All Colorado voters must also provide a valid mailing address when registering to vote. The mailing address can be a P.O. Box.


voters with a disability

The federal Help America Vote Act (HAVA) and Colorado law require that every polling place be accessible and that all voters are able to cast their votes privately and without assistance.

In Colorado, voters have access to new voting machines with assistive and adaptive technology (available at polling places in each county). Voters with disabilities also have the option to access their ballot and vote electronically.
