3 Ways to Register to Vote or Update your Registration
Attention CU students living on campus – please see our College Students page for instructions about how to enter your address so your mail ballot can find you.
Be sure to check the registration requirements on this page prior to registering. A registered voter in Colorado is considered a resident of Colorado for income tax and motor vehicle registration and operation.
Qualified residents may register to vote up to and including Election Day. However, in order to receive a ballot in the mail, the Boulder County Clerk & Recorder’s office must receive your voter registration no later than 8 days before the election. If you register after this time, you must visit a Vote Center in order to vote.
