How to Register to Vote
Visit the California Online Voter Registration website and complete the online application. To register online, you will need:

- Your date of birth.
Obtain a registration form from the City Clerk’s office, post office, libraries, Orange County Registrar of Voters, or DMV. It is important that your voter registration application be filled out completely and postmarked or hand-delivered to the Orange County Registrar of Voters at least 15 days before the election. Complete, sign, and mail the original form to the following address:

You should register to vote at least 15 days prior to any election. To receive a Voter Information Guide, you must be registered to vote by 29 days prior to the election.
Conditional Voter Registration
Conditional voter registration extends the existing 15-day registration deadline in California to eligible voters, allowing them to register and vote provisionally 14 days prior to an election and on Election Day. You can register and vote on the same day using the Conditional voter registration process as well. Visit the Orange County Registrar of Voters for more information on Conditional Voter Registration.
Vote Centers mean many more options for voters. Elections are no longer a one-day event. Voting begins the month before any election day when every voter will receive a vote-by-mail ballot. Take advantage of the alternatives available to avoid congestion – from voting-at-home, drive-thru ballot drop-off, in-person options, returning your ballot via United States Postal Service, or personally delivering your ballot to the Orange County Registrar of Voters – the choice is yours.
