Voter registration requirements were changed by the Help America Vote Act of 2002 (HAVA). Persons who register or re-register to vote after January 1, 2006, are required to include on their voter registration affidavits a California driver’s license number, if they have a current and valid driver’s license, or a California identification card number if they have one, or, if they have neither a driver’s license nor a California ID, the last four (4) digits of their Social Security number, if they have such a number.
