On Election Day, Voter Service and Polling Centers (“VSPCs”) will be open from 7:00 a.m. to 7:00 p.m. Mountain Time. If a voter is in line at or before 7:00 p.m., the polling center must remain open until the voter has cast their vote.
In Colorado, voters are also permitted to vote prior to Election Day. All active registered voters will receive a mail ballot, which they can mail in or drop off at a designated ballot drop box or VSPC. Alternatively, if a voter wants to vote in person, they can visit a VSPC in their county. Prior to Election Day, VSPC and ballot drop box hours may vary. Visit one of the links to find a VSPC or drop-off location in the correct county and to verify its hours: County Election Offices or Just Vote Colorado.
Voters can register up to and on Election Day, so long as they have been in the state for 22 days immediately before the election.
However, for a voter to receive a mail ballot, the voter must submit their paper registration/update form or online registration/update eight days before Election Day or submit an application through a voter registration drive no later than twenty-two days before Election Day.

To verify a location’s dates and hours, visit: Colorado Secretary of State’s website or JustVoteColorado.

In Colorado, it is illegal to register to vote or cast a vote while serving a sentence of detention or confinement for a felony conviction in a correctional facility, jail, or other location (which may include DOC inmate status, living in a community corrections halfway house or on non-residential status). Voters with misdemeanor convictions or those on probation or parole for a felony or misdemeanor conviction are eligible to register to vote and to vote in any election. A voter has the right to vote after having served a sentence of detention or confinement. If a voter was previously registered, that registration will have been canceled and they must re-register to vote. An individual currently serving a sentence in jail for a misdemeanor or being held in jail prior to trial on misdemeanor or felony charges CAN register and vote.
