Registration Deadlines

California requires voter registration to be received or postmarked by the county elections office 15 days before an election for regular registration. Online registration and mail-in registration follow the same 15-day deadline; exceptions and availability are described by Riverside County and the California Secretary of State. [1]

Conditional (Same-Day) Registration

California allows Conditional Voter Registration (same-day registration) at county elections offices and designated locations beginning the 14-day period before an election and continuing through Election Day. In Riverside County, conditional registration is available at the Registrar of Voters office and at polling locations where county staff are authorized to process conditional registrations. [2] [3]

Conditional registration lets eligible voters register and vote provisionally the same day if they miss the 15-day deadline.
