Colorado uses a vote-by-mail system for all elections, meaning that every active voter registered in advance receives a mail ballot. If you are an inactive voter, the county has sent a ballot to your address and it bounced back because you no longer live at that location.

To correct this you have to go online or to the county’s office to input your new address. The ballot will be sent to the mailing address you provided for your voter registration file.

If you prefer to vote at the polls, you can vote in-person at a voter service and polling center.
