  • Postmarked by: 29 days before Election Day.

Felony Information

Under Colorado law, if you've been convicted of a felony, you can register and vote when you are no longer incarcerated or on parole. You may vote if you're on probation. If you were incarcerated for a felony, you must submit a new voter registration form even if you were previously registered. For more information on how to register and vote after you've been released from parole, visit the Colorado Secretary of State.

Information for Students

  • You must be a resident of the state in which you register and vote. If you're a student from Colorado who attends school in another state, you may need to determine whether you're a Colorado resident or a resident of the state where you attend school. The important thing to keep in mind is that you may only cast your vote in one state.
  • Here's what Colorado says about residency: You may register and vote in Colorado if you have been a resident for 30 days preceeding the election. Your residence is your principal or primary home -- the place where you have a fixed place to live and that you intend to return to whenever you're away. Keep in mind that your voting address must be the same as the address you use for your motor vehicle registration and your state income tax forms. Some factors to consider in determining your residence include employment; income sources; age; marital status; residence of parents, spouse, and children, if any; leases; location of personal and real property; existence of any other residences; and the amount of time spent at each residence.
  • If you determine you're a Colorado resident, but will not be present in this state or will be away from your home district on Election Day, be sure to check the absentee ballot application requirements and deadlines. In addition, Colorado residents who attend school in-state, but in a different election district, may be eligible to register and vote in the election district where they live while attending school.
  • To determine whether you're a resident of a different state where you attend school, be sure to check that state's residency requirements.
