"Pursuant to California Elections Code section 2102(c), voters certify that they are eligible to vote by truthfully completing an affidavit of voter registration and signing the form under penalty of perjury.
The federal Help America Vote Act (HAVA) requires individuals registering to vote for the first time in the state/jurisdiction to prove identity and residency in the voting jurisdiction by providing either a valid driver's license or state ID card number.
Applicants who do not have either can provide the last four digits of their Social Security number.
When voters register to vote in Orange County, they provide the number of their California Driver's License or Identification Card. This number and the voter's name and date of birth must match the information for the voter on file with the Department of Motor Vehicles.
In order to register to vote, a person must:
Be a citizen of the United States;
Be a resident of California;
Be at least 18 years of age as of the day of the next election;
Not be in prison for the conviction of a felony; and
Not be deemed by an appropriate court to be mentally incompetent."
