Colorado ID Needed for Voter Registration

Your completed voter registration form must contain your Colorado driver's license number or your Department of Revenue ID number. If you do not have a driver's license or department of revenue ID number, then you will need to complete a paper registration form and provide the last four digits of your Social Security number. You cannot use a Social Security number when registering to vote 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.

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