Vote by Mail
Dominion Democracy Suite Voting System


As a California Voter’s Choice Act County, all San Mateo County registered voters will receive a ballot in the mail. Vote by Mail ballots may be returned to any Ballot Drop Box in the County, via the US mail, or to a San Mateo County Vote Center.

Ballots will look similar to past San Mateo County ballots, with a few differences. For instance, voters will now mark their ballots by filling in red ovals instead of black rectangles.
