(Redwood City, CA) Beginning Monday, October 4, 2021, authorized staff of the San Mateo County Registration & Elections Division will begin opening and processing returned Vote by Mail ballots for the November 2, 2021 Special Election for the Menlo Park City School District and the Town of Woodside.

Election officials may open the return envelopes containing voted mail ballots beginning 29 business days before Election Day. Operating hours for opening and processing will be daily, Monday through Friday, from 8 a.m. to 12:30 p.m. and 1 p.m. to 4 p.m., or when all ballots are processed for the day until the Official Canvass is complete.

For each ballot, an election official will compare the voter’s signature on the outside of the envelope to the signature on the voter’s original registration application or other updated signatures on file.

The ballot is separated from the envelope to preserve secrecy. The envelope is saved for the mandatory retention period, and the ballot is digitally scanned. The tabulation of the scanned ballots will not be reported until the close of voting at 8 p.m. on Election Day.

Those interested in observing the process may come to the Registration & Elections Division office at 40 Tower Road, San Mateo, at any time or make prior arrangements by contacting Elections Supervisor Hillary O’Connor at 650.312.5294 or Observers will receive a copy of the Election Observer Program Guidelines, which specifies observer rights, responsibilities and limitations, and a copy of the Vote by Mail Processing Procedures.

Registered voters may use the “My Election Info” link at or “Where’s My Ballot?” to verify when ballot materials were mailed and when the Registration & Elections Division received their voted ballot.

Tuesday, October 26, 2021, is the last day that registered voters may request a Vote by Mail ballot be delivered by mail for the November 2, 2021 Special Election.

Voted mail ballots can be returned in one of the following ways:
