Conditional Voter Registration (CVR) 
Voters who miss the voter registration deadline have the opportunity to “conditionally” register to vote and vote provisionally on the same day at a county Vote Center. Under this new law, once the county elections official processes the affidavit of registration, determines the individual’s eligibility to register, and validates the individual’s information, the registration becomes permanent and the CVR provisional ballot will be counted. 

Vote Centers currently open for the June Election from 8 5 p.m.:

Five additional Vote Centers will open daily beginning May 26 through June 4 from 8 a.m. to 5 p.m. (including weekends and Memorial Day)

All 39 Vote Centers will open June 2 through Election Day, Tuesday, June 5 from 7 a.m. to 8 p.m.

Changes of Name, Address or Party Affiliation
Voters must re-register whenever they move to a new address, change their name or would like to change political party affiliation. Registered voters who re-register are updating their existing record and not creating a new one.

Confirming Current Registration Status
Eligible and registered voters can confirm their current registration status online at by clicking on “Check My Registration.” The latest county registration statistics, updated weekly, are available under “Voter Registration.”

New Election Model for June 5, 2018
The June 5, 2018 Statewide Direct Primary Election is the first election conducted under the California Voter’s Choice Act (VCA). The VCA implements the All-Mailed Ballot/Vote Center model, with every registered voter receiving a Vote-by-Mail Ballot through the mail. The voted ballot may then be returned by mail with postage pre-paid envelopes, dropped off at any Vote Center or Ballot Drop-off Box located throughout the county.

Vote Centers replace traditional polling places and are open for voting throughout the early voting period. Vote Centers provide expanded voter services such as voter registration, multilingual assistance, and disabled access voting options.
