Voters may drop off completed ballots in drop-off boxes located in each community or mail them in the provided postage-paid envelope.

Those who regularly vote by mail shouldn't notice much difference in the upcoming election, but others may have to make some adjustments, as most local polling places will no longer be open.

Several jurisdictions in the county have held similar elections in the past, but this will be the first such countywide election.

The June 5 primary election will be unlike any other election ever held in San Mateo County, with every voter receiving a ballot in the mail and the choice of either voting by mail or in person at a limited number of voting centers.
