Your official mail ballot envelope has a barcode that identifies it as yours. When you return your voted ballot to the Registrar of Voters, your mail ballot envelope is scanned on a mail sorting machine, capturing an image of your signature.

County staff will verify your signature on the mail ballot return envelope matches the signature on file with your voter registration before the ballot is removed from the envelope and counted with other mail ballots with high-speed, accurate scanners. How you vote is private as there is nothing on the ballot itself that identifies it as yours.

If you do not sign the envelope or staff determines the signatures do not match, you will be notified by letter at least eight days before the election is certified and be given until two days before certification to resolve the issue. The Registrar of Voters must certify the results of this election no later than December 1.

Double Voting. Attempting to vote more than once is a crime punishable by up to three years in prison. Elections Code section 18560(b). Voters who attempt to vote more than once in an election will be referred to the County District Attorney for investigation and potential prosecution.

If a voted mail ballot is returned after a voter has already voted at the Registrar of Voters office, an early vote site, or a polling place, the mail sorter recognizes and rejects the second ballot. If a voter attempts to vote in person after returning a voted mail ballot, election workers will check in the voter using an electronic roster (or Poll Pad) that will identify that the voter has already voted in the election. If the voter states he or she has not voted in this election, the voter may vote a provisional ballot that is placed in an envelope and County staff will research the voter’s participation in the election before rejecting or accepting the provisional ballot.
