Ways to Vote
Vote-by-Mail Ballots
All active California registered voters will receive a vote-by-mail ballot for the Primary Election. After you complete, seal and sign your ballot, you can drop it off at an official dropbox or an early voting site, or you can return it by US Mail.
- You must drop your completed ballot off no later than 8 PM on Election Day, November 3.
- See Contra Costa County 2026 General Election for the Official Ballot Drop Boxes lists.
- You must drop your completed ballot off no later than 8 PM on Election Day, November 3.
- See Contra Costa County 2026 General Election for the Regional Early Voting Sites lists.
- Mailed ballots must be postmarked no later than November 3.
- If mailing on Elections Day, get a hand-stamped postmark from a postal employee inside a United States Post Office.
MAIL YOUR BALLOT BACK EARLY!
To ensure your ballot is postmarked by Election Day, make sure you mail it at least 5 business days before Election Day.
Postmarks are applied by machines at processing facilities, not at local post offices. Recent transportation changes may result in mail not arriving at the processing facility on the same day that it is mailed. This means that the date on the postmark might not match the date you mailed your ballot, so you must mail your ballot early!
Vote in-person on election day:
- On Election Day, you can vote in person at any polling place within the county between 7:00 am and 8:00 pm. However, your pre-printed ballot type is only available at your designated polling place. You can find your assigned polling place printed on the back of your Voter Information Guide or by using the My Voting Information Look-up tool.
- On Election Day, you may vote in person at the Elections office from 7:00 am to 8:00 pm. The Elections office is located at 555 Escobar Street in Martinez
