Are you voting using a vote by mail ballot?
Be sure to SIGN & DATE your ballot return envelope - even if you’re dropping it off at a voting location or ballot drop box!
The signature is matched to one on file for verification. Writing the date can help if a postmark is unclear.
Note: Vote by mail signatures must be verified for a ballot to be counted.

If a signature is missing or does not match the one on file with the elections dept., then the ballot is “challenged” and cannot be counted. Voters in California are sent a notice and have an opportunity to “cure” (fix) the problem, so their ballot can be counted.
