Colorado allows for same-day voter registration, meaning that you are able to register to vote in-person at a voter service and polling center up until Election Day, November 3, 2026.
Eligibility
In order to register to vote, you must be a U.S. citizen, have Colorado residency for at least 22 days prior to election day, be at least 15 years old, and not be an incarcerated felon.
- College students have a choice of whether they want to vote in Colorado or vote in their home state, but they may only be registered and vote at one location. In order for an out-of-state student to register to vote in Colorado, they must claim Colorado residency. Learn more about voting as a college student here.
- You can register to vote if you are at least 16 years old, but can only vote if you will be 18 by Election Day.
- In Colorado, those convicted of a felony are disenfranchised only as long as they are incarcerated; those on parole, probation, or with unpaid restitution and fines regain their right to vote.
Deadline
Colorado has same-day voter registration, meaning that you are able to register to vote up until the date of the election.
