Register to Vote

Register to vote or confirm your voter registration at SD County’s voter registration page. You must register by Monday, October 19, 2026 to be eligible to vote in the November 3 General Election.

Receiving and Tracking Your Mail-in Ballot

All active registered California voters will receive a ballot by mail. Ballots begin mailing on October 5, and for more information on voting by mail, tracking your ballot, ensuring your vote was received and counted, requesting a replacement ballot, and more, visit SD County’s Vote by Mail page.

NEW and IMPORTANT deadline to Mail-In Ballots

If you are voting by mail, it is critical that you mail your ballot—or drop it off at a post office—no later than Tuesday, October 27. New postal processing practices mean that some mail may not receive a same-day postmark, which could delay your ballot. Mailing your ballot early helps ensure it is received and counted. If you are mailing your ballot on Election Day (November 3), ask a postal employee to hand-stamp it with that day’s postmark.

Dropbox Locations

The safest place to return your mail-in ballot is an Official Ballot Drop Box. From Tuesday, October 6, until 8 p.m. on Tuesday, November 3, drop off your ballot at any of the Registrar’s official ballot drop boxes located throughout the county. Click here to find Drop Box locations in your area.

In-Person Voting

You can also vote in person if you prefer. Early vote centers in San Diego County will be open on Saturday, October 24, Saturday, October 31, and on Election Day, Tuesday, November 3. Click here for more information.
