Vote By Mail Ballots


Receive a Vote by Mail Ballot

Every Voter registered to Vote by Mail in districts holding an election will be mailed a ballot beginning 29 days before Election Day.

The ballot will come in an envelope that looks like this:

Inside the ballot packet you will find:

  • Your Official Ballot
  • The postage-paid return envelope

Voting by mail is easy!

  1. Vote your ballot by filling in the box next to your choice.
  2. Put your voted ballot inside the lavender postage paid return envelope.
  3. Sign the return envelope between the hole punches. (This is important! In order to count your ballot, we must match your signature on the envelope with the signature in your voter registration record.)
  4. Seal the envelope.
  5. Return the ballot.

Return Your Ballot

Don’t delay! Once you vote your ballot and properly sign the envelope, you need to return it on time. Here’s how:

  1. Mail it in the return envelope. It can only be accepted if it is postmarked on or before Election Day, and received by our office within three (3) business days after Election Day.
  2. Drop it off at our 24-hour drop box at 40 Tower Road, San Mateo until 8 p.m. on Election Day.

Emergency Vote by Mail Voting – Authorized Ballot Pick-up

If, during the seven (7) days before an election, you find that you will be unable to vote in person on Election Day, you may request in a written statement, signed under penalty of perjury, that a ballot be delivered to your authorized representative. Your authorized representative will receive your ballot after presenting the signed statement at the San Mateo County Registration & Elections Division.
