The provisional ballot envelope serves as an affidavit. When you vote with a provisional ballot, you’re required to provide two pieces of information on your provisional ballot envelope:
Your Colorado driver’s license number OR a Department of Revenue ID number
Your entire Social Security number OR the last four digits of your Social Security number
If you don’t provide any of the above information, your ballot may not be counted! If you don’t provide any of this information, you still have the right to vote with a provisional ballot.
If you vote with a provisional ballot, your vote will not be counted until your County Clerk can verify that you’re registered to vote. Your County Clerk will match information on your provisional ballot to identifying information on the master voter registration list in your county.
This information includes the name of the voter and identifying information (such as the last four digits of the voter’s Social Security number, the voter’s driver’s license number, a Department of Revenue ID number, or a unique identifying number assigned at the time of the voter’s registration).
The information you provide on your provisional ballot envelope will help your County Clerk verify that you’re registered to vote. If the County Clerk cannot verify that you’re registered to vote, your vote will not be counted.
