How to Vote

Voting is the fundamental right of every U.S. citizen. The San Mateo County Registration & Elections Division strives to uphold and preserve this right through voter registration, voter education and accessible voting options.

Here you will find information on where, when and how you can vote.

As a voter, we thank you for partnering with us in this core element of democracy. 


Vote by Mail/Drop Box

Every registered voter in San Mateo County will be mailed a ballot beginning 29 days before Election Day. Here you will find more information on Vote by Mail ballots and the different ways you can return your voted ballot.


Vote Centers
Vote Early or on Election Day

California law allows voters to cast their ballot during the 29-day period prior to Election Day and on Election Day. You may cast your ballot via mail, or vote in person on paper or using the ballot marking tablet.


Dominion Democracy Suite Voting System

Beginning with the November 5, 2019 Consolidated Municipal, School and Special District Election, San Mateo County adopted the Democracy Suite Voting System from Dominion Voting Systems. The San Mateo County Board of Supervisors approved a contract to lease the new system on July 9, 2019. The system was also successfully deployed for the March 3, 2020 Presidential Primary Election, and will be used for the November 3, 2020 Presidential General Election.

Democracy Suite is a fully integrated, highly secure voting system. Using the Democracy Suite system will result in upgrades to multiple components of the County’s election system, including touchscreen ballot marking tablets and ballot printers in the Vote Centers for an improved voter experience. Additionally, the system will provide faster scanning technologies, and improved election security and management at the County’s Registration & Elections Division office.
