Register to Vote

Update Voter Registration

Update or view your voter registration online and change your address or political party affiliation. Or if you prefer, you may print and complete the paper registration form and return it to us. (Please note, if you have previously requested 'confidential status,' you will not be able to view your voter registration online and must use the paper form.)

Register as Military/Overseas Voter

Register to vote as a UOCAVA voter if you are a military service member or his/her dependents absent from the state because of active duty, or a citizen living overseas. 

Request a Temporary Address for your Ballot

Will you be out of town during election season? Whether you are a college student, snowbird or simply going on vacation, you can update the mailing address on your voter registration in order to receive your mail ballot in another town, state or country. Remember to change it again after you return! (Note, your residential address must still be in Arapahoe County.) 

Change Name

Print and complete the paper registration form with your new legal name and return it to us at the address below. Sorry, Colorado does not allow voters to change their name online. 

Withdraw Registration

If you are moving out of Colorado, please withdraw your voter registration online or complete the paper withdrawal form and return it to us at the address below. A voter may not cast ballots in two states.

Request Confidential Status
