If you moved from out of state, you are only eligible to register if you have been a resident of Colorado and the precinct in which you want to vote for at least thirty days prior to the day of the election in which you want to vote. If you have a Colorado driver’s license or an ID card issued by the Department of Revenue, you may register online. However, if you do not have these forms of identification, you can register by mail or in-person at the county clerk’s office.
If you moved from out of state, you are only eligible to register if you have been a resident of Colorado for at least thirty days prior to the day of the election in which you want to vote. But under federal law, if you move within thirty days of a presidential election, you are allowed to vote for President and Vice President in your former state of residence, either in person or by absentee ballot.
If you moved to a new address within the state, you can update your address online if your signature is stored in digital form with the Colorado Department of State. You may also submit a letter or form to the county clerk’s office to update your registration records. The online and paper forms are available here: https://www.sos.state.co.us/Voter/secuRegVoterIntro.do.
Many registered Colorado voters who move are still entitled to cast a ballot that will be counted — even if they did not notify the appropriate election official about the move before Election Day and the election official has not changed their registration.
During the twenty-eight days before Election Day and on Election Day, change your address and vote at the office of the county clerk and recorder.
On Election Day, cast a provisional ballot at your new polling place, if you have not yet changed your address at the office of the county clerk and recorder. The provisional ballot is counted if election officials confirm you are eligible to vote at your new polling place.
If you moved to a new address in a different polling place within the same county during the 29 days before an election you can vote at the polling place associated with your old address on Election Day, by mail-in ballot, or by early voting. If you vote in-person on Election Day, you will need to sign a change of address form. Alternatively, you may vote by provisional ballot at your new residence.
On Election Day, cast a provisional ballot in your new county, if you have not yet changed your address at the office of the county clerk and recorder. The provisional ballot is counted if election officials confirm you are eligible to vote in your new county.
If you moved to a different county within the state during the 29 days before an election you may vote at the polling place associated with your old address, by early voting, by mail-in ballot, or by a provisional ballot and affidavit at the polling place associated with your new residence.
