Please visit registertovote.ca.gov to complete an online voter registration form. To be eligible to vote in the November election, your paper application must be postmarked by Monday, October 21, 2024. Online applications must also be submitted by that day. DID YOU KNOW that 16- and 17-year-olds can pre-register to vote? Pre-registered teens will then automatically become registered to vote on their 18th birthday.
