Am I eligible to vote in Colorado?

In Colorado, you are eligible to vote if you are a U.S. citizen, at least 18 years of age on Election Day, registered to vote, and a resident of the State of Colorado for a minimum of 22 days prior to the election.

In 2013, Colorado became the first state to allow 16- and 17-year-old citizens to pre-register to vote when they got their driver's license. Within four years, more than 150,000 young people took advantage of that change in the law and in 2018, 60% of young people in Colorado voted, far exceeding the national average of 30%. If you would like to pre-register to vote, see Voter Registration below.

In Colorado, you cannot register and vote if you are currently serving a sentence in a correctional facility for a felony conviction. On the day you are released from incarceration or detention, you become eligible to register to vote. You must re-register to vote as your prior registration will have been canceled.

You can register and vote if you are:

  • On parole or probation
  • In jail, while awaiting trial or out of jail on bond while a criminal case is pending
  • In a state institution for those with behavioral or mental disorders. As long as you are registered to vote, would like to vote, and have the ability to direct how you would like to vote, you are allowed to vote in Colorado.
  • Homeless or without a fixed permanent residence

Where Do I Vote?

You can return your mail-in ballot or vote in person at a Voter Service and Polling Center by 7 pm on Election Day.
