Voting in Colorado

When You Can Vote

Election Day

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.

If You Are in the Military or Are an Overseas Voter

Military and other overseas citizens may use the standard procedure for early voting by mail, but there are also special provisions for members of the U.S. Armed Forces and Merchant Marine, commissioned corps of the Public Health Service and National Oceanic and Atmospheric Administration, along with family members of all these groups, and other citizens who reside outside the United States.  These individuals are known as UOCAVA voters.

Registering and Requesting an Absentee Ballot

UOCAVA voters can use the Federal Post Card Application (FPCA) to register to vote and to request an early ballot at the same time.  Visit here to access the FPCA. A voter can submit the FPCA by mail, email or fax.  To submit by mail, download and complete the FPCA and mail it to an election official.  To submit by email, scan the signed FPCA into a computer.  Be sure to include the Electronic Transmission Sheet.  Email this package directly to an election official. If a voter chooses to fax their FPCA to their election official, they also must include the Electronic Transmission Sheet. To register for upcoming elections in Colorado, the FPCA must be mailed by November 2nd for the November 2nd general election. The FPCA must be received by the eighth day after Election Day.

Receiving and casting an Absentee Ballot

UOCAVA voters may receive their absentee ballot by mail, email or fax.  They may submit their completed ballots the same way: by mail, email, or fax.  Ballots must be sent by Election Day: for the 2021 general election it must be sent by November 2nd at 7:00 p.m.  Ballots must be received by the eighth day after Election Day.

Federal Write-In Absentee Ballot

The Federal Write-in Absentee Ballot (FWAB) is a back-up ballot that can be used by all UOCAVA voters.  UOCAVA voters use the FWAB to write in their votes when they have not received their early voting ballot in time.  If a UOCAVA voter is not registered, the local election office will treat the information submitted in the FWAB transmission envelope as the voter’s registration application.  The FWAB form is available here. FWAB ballots must be sent by Election Day; for the 2021 general election, it must be sent by November 2nd at 7:00 p.m.  They must be received by the eighth day after Election Day.

If You Have a Criminal Record

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.
