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, November 1 is the last day that registered voters may request a replacement Vote by Mail ballot be delivered by mail for the November 8, 2022 Statewide General Election. The deadline ensures that there is enough time for postal delivery. To request a replacement ballot after November 1, please go to any Vote Center in San Mateo County.
