Information on how to register to vote in California
www.sos.ca.govYou can register (or update your registration) in California online, by mail, or in person, and California has clear registration deadlines tied to each election.[1][6]
How to register in California (3 ways)
- Online (start or update your registration on California’s election website).[1]
- By mail (use the National Mail Voter Registration Form if you’re mailing in).[1]
- In person (register through California’s election website / your county elections office).[1]
What you’ll need
California generally requires identification details such as your California driver’s license/ID number (or the last four digits of your Social Security number), plus your date of birth and residential info/address details.[2][9]
Deadlines (important)
Registration deadlines vary by election. For example, NPR’s 2026 California voter registration roundup for the June 2 primary lists: online by May 18, by-mail postmarked by May 18, and in-person registration by June 2.[5]
If you miss the deadline, California may still allow eligible “conditional” registration at county elections offices, polling places, or vote centers (with ballot counting after the county verifies your registration).[5]
Check your registration status
You can confirm your voter registration status on California’s election website.[1]
If you tell me which election date you’re targeting (e.g., June 2, 2026 primary vs. a different election), I can help you interpret the correct deadline and the fastest method for your situation.
