Provisional Voting

There are two circumstances in which you have a right to cast a provisional ballot in an election in California. First, if you believe you are registered to vote, but your name does not appear on the voter list at a polling location, you can vote provisionally. Second, if you voted by mail, but the county does not have a record of receiving your vote-by-mail ballot, you can vote provisionally. 

Any eligible voter, including those displaced by wildfires, can cast a provisional ballot at any polling location in the county, and that ballot will be placed in a special provisional envelope before being put in the ballot box. Only the races you are eligible to vote in will be counted. A provisional ballot will be counted after county election officials confirm that you are registered to vote and have not already cast a ballot in this election. 

Any voter who votes provisionally has a right to know whether their provisional ballot was counted. Click here to find the status of your provisional ballot.
