“Online pre-registration is now available for eligible 16 and 17 year olds by visiting registertovote.ca.gov. California youth who pre-register to vote will have their registration become active once they turn 18 years old. Pre-registration does not change the voting age, which is 18. Instead, it allows eligible Californians ages 16 or 17 to complete the online voter registration form providing sufficient time and opportunity to get ready to vote.” – Alex Padilla, California Secretary of State
