Please check out the Colorado Secretary of State page for state wide information about elections and voter registration. You can find voter registration forms there, including mail in ballot registration.
If you have moved or changed your name, you need to update your registration. All elections in Colorado are now mail-in ballot elections only. If you are registered, you will automatically receive ballot information in the mail. You can pick up a voter registration form at Town Hall, the County Clerk’s Office, or update your registration information online: https://www.sos.state.co.us/voter-classic/pages/pub/home.xhtml. You can also download the registration form using the link below.
