Register and Be a Voter

California Online Voter Registration

California maintains a statewide voter registration database. Eligible voters may register online by clicking here. The signature on file with the DMV will be used as your voter registration signature, unless you print, sign and mail your voter registration application. Please keep in mind that vote-by-mail ballots are verified against the signature in the voter registration record.

To register to vote in California, you must be:

  • A United States Citizen
  • A resident of California
  • 18 years or older on Election Day
  • Not currently serving a state or federal prison term for the conviction of a felony
  • Not currently found mentally incompetent to vote by a court of law

To pre-register to vote in California, you must:

  • Be 16 or 17 years old
  • Meet all the other eligibility requirements. 

Pre-registered voters will be automatically registered to vote on their 18th birthday. A pre-registered voter should update their registration information if, upon turning 18, the voter has moved, changed their name, political party, mailing address, or signature. Some voters who registered at 16 or 17 years old have significant changes to their signature prior to their first election. 

About Addresses

You must register to vote at the address where you live. You may have any mailing address you wish.

Your residence address entitles you to vote in a particular city, school district, special district, and state and federal legislative districts. PO Boxes and private mailboxes (PMBs) are not considered a domicile.

If you are unsheltered or homeless, you only need a description of where you live. If you do not have a street address, provide an exact description, including cross streets. If applicable, identify the corner or area where you live. For instance: "Northwest corner of 1st St and Court St."

When to Re-Register

You must re-register to vote when you:

  • change your name (or if you would like it to match your driver's license)
  • change your address
  • want to change your political party affiliation
  • want to update your signature

Confidential Voter Registration

The voter registration file is not available to the general public; however, certain information is available to qualified applicants for political, election-specific, journalistic, scholarly, or governmental purposes. This is how campaigns get mailing lists and academics get data for research.

By becoming a confidential voter, all of the voter's information is kept private and is not available to others for any purposes. Voters who are in one of three categories may participate in confidential registration; however, the voter must take action to qualify. For details, please see our "Confidential Voter" webpage.
