If I am voting by mail, when must the county clerk and recorder receive my ballot?
Mail ballots must be received by the county clerk and recorder no later than 7:00 p.m. on Election Day. Voters are encouraged to drop off ballots at designated drop-off locations, drop-box locations, or mail them in time to be received by the county clerk before the polls close.
