Primary Election

The following deadlines apply to the state of California, and might be different from other states within the United States

Voter Registration Deadline

Postmarked by February 20, 2024, or you can register and vote at your county elections office after the 15-day voter registration deadline.

Conditional Voter Registration is a safety net for Californians who miss the deadline to register to vote or update their voter registration information. Voters can use the conditional voter registration process from the day after the deadline all the way through Election Day. Eligible citizens can go to their county election office, polling place, or vote center to register and vote conditionally. These ballots will be processed once the county elections office has completed the voter registration verification process.
