You must have a valid Social Security Number, Colorado driver’s license or Colorado ID card to register online.

If you do not have any of these forms of ID, please check the appropriate boxes on the paper registration application form. A unique identifying number will then be assigned to you by the state and you will still be registered to vote. However, if the identification section is left blank and you do not check the box(es) indicating you do not have identification, you will not be registered to vote.

Colorado now has automatic voter registration! When you interact with certain agencies, such as the DMV, you usually provide information like your name, address, date of birth, etc. This information is then used to register you to vote in Colorado. The county clerk will verify that they have the complete record to register you to vote. If your record is complete, the county clerk will send a notice to you that you are registered to vote. You can return the notice to either decline to be registered or to affiliate with a political party. If you do not decline to be registered within 20 days after the notice is mailed, and the form is not returned as undeliverable, you are then registered to vote.

For more information please contact your county clerk and recorder or contact your local League for more information.
