How to register and acceptable ID

California offers multiple ways to register: online, by mail, or in person. When using the state online portal you will be asked to provide a California driver license or identification card number, or the last four digits of your Social Security number; if you do not have those you may be required to submit a signed paper registration by mail. For in-person registration and polling place check-in the San Diego County Registrar of Voters verifies identity and residence using the voter record and available documentation. [1]

  • Register online using the state portal with CA driver license/ID or last four of SSN.
  • Mail a signed voter registration form; include required identification info as directed.
  • Register in person at designated county registration sites or the Registrar of Voters office.
  • Observe registration deadlines published by the state and county for each election.
If you lack a driver license or SSN, register by mail and follow the instructions to complete identity verification.

Voting day ID and provisional ballots

California generally does not require presentation of photo ID for most voters at polling places, but election officials confirm identity against the voter registration record. If an election official cannot verify your registration at the polling place, you may be offered a provisional ballot and instructed how to cure it. For specifics on provisional ballots and ID verification, consult county and state guidance. [2]

  • If check-in cannot confirm your registration, you may cast a provisional ballot.
