How to Vote

You have several options to submit your ballot:

Mail — Postmark on or before Election Day. Your signature should match the name you registered with or on your CA driver’s license.
Tip: SLO County’s nearest postal hub is in Goleta (50+ miles away). Mail 7–10 days early — or take it inside a post office for a hand-stamped postmark.
No Envelope? — Bring your vote-by-mail ballot to the County Elections Office in SLO, or in Atascadero starting October 26, and sign a short form there. Staff will verify your signature on the spot and give you a privacy sleeve so you can vote right then. This option is available only at the elections offices, not at drop boxes or polling places, and these ballots are counted early on election night.
Drop Box — Deposit your sealed ballot in an official drop box starting October 6. Find drop box locations.
Polling Place — Vote in person, drop off, or register. Look up your polling place.
Track — Sign up to track your ballot.
