Ballots have been mailed to all registered voters for the November 4, 2025 Statewide Special Election.

If you make a mistake on your ballot, you may get a replacement ballot during an election.

Replacement ballots are a normal part of the Vote by Mail process. Voters may receive additional ballots if they re-register, update their voter registration or request a replacement from our office. Only the first ballot our office receives will be counted, ensuring NO ONE can vote twice.

Tuesday, October 28, was the final day that registered voters could request a replacement Vote by Mail ballot be delivered by mail for the November 4, 2025 Statewide Special Election. The deadline ensures that there is enough time for postal delivery. To request a replacement ballot after October 28, please go to any Vote Center in San Mateo County.

If you want a representative to pick up a replacement ballot for you, please fill out and sign the Application to Provide Vote-by-Mail Ballot to Representative. The representative must come to the Elections Office or any Vote Center to receive the ballot.
