Are there circumstances under which a voter can be required to Vote by Mail?

If a city or district chooses to have a special election, it may choose to have it held by mail. The Registration & Elections Division office at 40 Tower Road in San Mateo will serve as a Vote Center for those who wish to vote in person, need a replacement ballot, would like language assistance or to use our accessible Ballot Marking Tablet.

How can I apply to work at a Vote Center?

Fill out the online Vote Center Representative application form.

What do I do if I move before the election?

If you move within San Mateo County 14 days or less before the election, go to any Vote Center to update your local address on your check-in form and vote.

I am disabled/physically challenged. Is there any assistance for me?

Our voting system is compliant with the Help America Vote Act (HAVA). It has audio headphones, raised braille labeled keys and adaptive devices that provide large tactile buttons for motor issues as well as sip-and-puff capability. We also provide curbside voting if you cannot enter the polling place. A Vote Center Representative may set up a voting station outside or bring a paper ballot to your vehicle to enable you to vote.

Voters who wish to have a copy of the Sample Ballot & Official Voter Information Pamphlet provided to them in an audio format prior to the election may contact the San Mateo County Registration & Elections Division by phone or text at 650.312.5222 and request assistance.

If a voter prefers to vote at home, he/she can use a Vote by Mail ballot or our Remote Accessible Vote by Mail system.

In 2017, the County of San Mateo introduced a home-based accessible system which allows voters with disabilities to vote privately and independently by accessing and marking an electronic ballot in a screen-readable format on any computer. Voters using this system will log in online, mark their choices and then print the ballot out. The ballot would then need to be returned to the Registration & Elections Division.
