You can register to vote if you will be 18 years old by Election Day, are a citizen of the United States, and have lived in Colorado at least 22 days prior to Election Day. In order to receive your ballot by mail, register or update your voter registration online through the 8th day before Election Day. Refer to your county’s website or office number below for voter registration and information.

Colorado voters can register through Election Day, but must register at least eight days prior to Election Day to receive a ballot in the mail. Voters who register after that day may register and pick up a ballot in person at their county's Voter Service and Polling Center.
