Same Day Voter Registration, known as Conditional Voter Registration in state law, is a safety net for Californians who miss the deadline to register to vote or update their voter registration information for an election.
Eligible citizens who need to register or re-register to vote within 14 days of an election can complete this process to register and vote at their county elections office, polling place, or vote center. Their ballots will be processed and counted once the county elections office has completed the voter registration verification process.
