In the state of Colorado, you need a Colorado driver's license, a Colorado Department of Revenue identification number, or the last four digits of your social security number to register to vote in person. When you get your driver's license, you can automatically register to vote at the DMV. The last day to register to vote in a specific election is 29 days before that election.
Voter Registration Requirements:
- You must be a U.S. citizen.
- You must be 18 years of age on or before the date of the election.
- You must reside in Colorado at your present address for at least 30 days before the election.
For voter registration forms, please visit the Colorado Secretary of State website. The form takes 20 days to process. If you do not have a Colorado driver's license, additional identification may be required if registering to vote by mail.
Where to Vote:
Although the majority of local elections are held through mail-in ballots, polling locations are available throughout the state of Colorado for major elections. If you are already registered to vote, you can find the nearest polling place at Elections Information for Voters.
Voting in Denver:
The city attempted to replace polling places with vote centers in 2006, but has since reverted to polling places and mail-in ballots. The vote centers led to long lines due to technical difficulties, and caused the Clerk and Recorder to resign in disgrace. Visit How to Vote for the latest updates on the voting process in Denver.
Voting and Criminal Convictions:
In Colorado, convicted felons keep the right to vote as long as they have served their sentence and are not currently on parole. Felons currently incarcerated or on parole cannot vote. However, if you are in jail or on parole for a misdemeanor, you can still vote.
