California ID Needed for Voter Registration

To register to vote in California you will have to provide your California drivers' license number or identification card number or the last four digits of your Social Security Number (SSN). If you do not include this information you will be required to provide identification when you vote.

If you register to vote by mail and submit a driver's license number that the state or local elections official can match with an existing state identification record, then you will not be required to provide identification when you vote.
