Resolving Unsigned and Non-Matching Signatures for Mail Ballots and Provisional Ballots

When the Registrar of Voters receives a voted mail ballot or provisional ballot without the voter’s signature on the identification envelope or is unable to compare the voter’s signature on the return envelope with the signature on file in the voter’s record, the Registrar of Voters is unable to count that ballot. However, California law allows voters another chance to correct their mail ballot or provisional ballot up until two days before the election results are certified. These voters are notified by mail that they may:

  • Go to the Registrar of Voters in person to sign the mail ballot or provisional ballot identification envelope or sign the Signature Verification and Unsigned Identification Envelope Statement;
  • Complete and return a Signature Verification and Unsigned Identification Envelope Statement; or
  • Fix the unsigned ballot identification envelope online.

If you received a letter from the Registrar of Voters stating that your mail ballot or provisional ballot return envelope was not signed or your signature did not compare with your signature on file, go to the Registrar of Voters to sign your envelope, or complete and return a Signature Verification and Unsigned Identification Envelope Statement immediately.

For mail ballots:
