We have been alerted to a theft of ballots and other mail from a USPS location in Daly City. As in every election, voters are encouraged to track their ballots on WheresMyBallot.sos.ca.gov. See our Press Release about the incident here: smcacre.gov/elections/news/r… @sanmateoco
Ten Vote Centers are open throughout San Mateo County 9 a.m. to 5 p.m. every day (weekends included!) At a Vote Center, you can vote in person, register and vote same-day, request a replacement ballot, and more. See smcvote.gov for more info!

Don’t forget to sign your Vote by Mail ballot envelope! Your ballot cannot be counted without a valid signature that compares to the one in your record.
@sanmateoco
You can drop your ballot off at an official Drop Box, at a Vote Center, or with USPS. If you are mailing your ballot close to E-Day, take it inside a post office to get a hand postmark. Ballots must be postmarked by November 3 and received by November 10 to be counted! smcvote.gov
If you missed the Voter Registration Deadline, you can still vote! Go to any open Vote Center to register and vote same-day. Starting this weekend, 10 Vote Centers will be open every day — Saturday and Sunday too!

If you think about it, in California, Election Day is really just the LAST day to vote. In San Mateo County, voting is as simple as marking your ballot, signing your envelope, and popping it in a Ballot Drop Box. Questions? We’re here to help!

If you are mailing your ballot on Election Day (November 3), take it INSIDE the post office and get a manual postmark from a post office employee. Otherwise, your ballot might be postmarked late. Mailed ballots must be postmarked on or before Nov. 3 and received by Nov. 10.
To ensure your ballot is postmarked by Election Day, make sure to mail it at least 7 days in advance. Mailed ballots must be postmarked on or before November 3. @sanmateoco
