  • By phone: Call your county clerk and recorder’s office to request that a paper copy of the registration form be mailed to you. You can mail, email, fax or hand-deliver the completed form.  
  • In person: Visit your county clerk and recorder’s office to pick up and submit a registration form. You can also register at the Division of Motor Vehicles and other state and federal offices, as well as at voter service and polling centers through Election Day. If you’re eligible to vote, you’ll automatically be registered when you renew or apply for your driver’s license.
