Register to Vote

If you have not registered to vote, or if you have any change to your name, residence address or mailing address, you must register to vote 15 days prior to the general election to be able to vote.

You can register to vote online here.  

Voter registration cards can also be found in the following locations:

• Local Post Office
• Department of Motor Vehicles
• Local Library
• Local City Clerk Offices
• Contra Costa County Elections Office

Apply to Vote By Mail

Any registered voter may vote by “absentee ballot” also known as “voting by mail.” The last day the county election office may accept applications by mail is 7 days before an election. A voter may receive a ballot in the county election office, in person, up to and including Election Day. However, if you know you are going to vote absentee, it is in your best interest to apply as early as possible.

The Contra Costa County Elections Division can provide you more details.
