(a)

1. (1) Upon receiving a vote by mail ballot, the elections official shall compare the signature on the identification envelope with either of the following to determine if the signatures compare:

   1. (A) The signature appearing on the voter’s affidavit of registration or any previous affidavit of registration of the voter.
   2. (B) The signature appearing on a form issued by an elections official that contains the voter’s signature and that is part of the voter’s registration record.

2. (2) All of the following apply to the comparison of signatures pursuant to this section, including the comparison of a voter’s signature on a signature verification statement, an unsigned identification envelope statement, or a combined vote by mail ballot signature verification statement and unsigned identification envelope statement, with the signature that is part of the voter’s registration record:

   1. (A) A presumption exists that the signature on the identification envelope, signature verification statement, unsigned identification envelope statement, or provisional ballot envelope is the voter’s signature and that the vote will be counted.
   2. (B) An exact match is not required for an elections official to determine that a voter’s signature is valid. The fact that signatures share similar characteristics is sufficient to determine that a signature is valid.
   3. (C) Except as provided in subparagraph (D), the elections official shall consider explanations for discrepancies between signatures that are specified in regulations promulgated by the Secretary of State. For purposes of this subparagraph, explanations include a variation in signature style over time and the haste with which a signature is written.

   4. (D) When comparing signatures, an elections official shall not review or consider any of the following:

      1. (i) A voter’s party preference, race, or ethnicity.
      2. (ii) A voter’s identifying information including gender, name, or address, except to confirm the identity of the voter.
      3. (iii) The amount of time spent reviewing a signature.
   5. (E) The elections official may consider characteristics of the written signature that are specified in regulations promulgated by the Secretary of State. For purposes of this subparagraph, characteristics include the slant of the signature, letter formation, and whether the signature is printed or written in cursive.
   6. (F) The elections official may use facsimiles of voters’ signatures, provided that the method of preparing and displaying the facsimiles complies with the law.
   7. (G) In comparing signatures pursuant to this section, an elections official may use signature verification technology. If signature verification technology determines that the signatures do not compare, the signature is subject to the additional procedures described in paragraph (2) of subdivision (c).
   8. (H) The variation of a signature caused by the substitution of initials for the first or middle name, or both, is not grounds for the elections official to determine that the signatures do not compare.
   9. (I) A signature made using a mark such as an “X,” or made by a signature stamp, shall be presumed valid and shall be accepted if the signature meets the requirements of Section 354.5.

(c)

1. (1) If upon conducting the comparison of signatures pursuant to subdivision (a) the elections official determines that the signature possesses multiple, significant, and obvious differing characteristics when compared to all signatures in the voter’s registration record, the signature is subject to the additional procedures described in paragraph (2).
2. (2) If the elections official makes the determination described in paragraph (1), the signature shall be rejected only if two additional elections officials each find beyond a reasonable doubt that the signature differs in multiple, significant, and obvious respects from all signatures in the voter’s registration record. If the officials determine that the signatures do not compare, the identification envelope shall not be opened and the ballot shall not be counted. The elections official shall write the cause of the rejection on the face of the identification envelope only after completing the procedures described in subdivision (d).

(d)

1. (1)

   1. (A) Except as provided in subparagraph (E), on or before the next business day after a determination pursuant to paragraph (2) of subdivision (c) that a voter’s signature does not compare pursuant to subdivision (c), but not later than the applicable notification deadline after the election, the elections official shall send by first-class mail notice to the voter of the opportunity to verify the voter’s signature no later than 5 p.m. on the day of the applicable receipt deadline after the election. The notice shall include a return envelope, with postage paid, for the voter to return a signature verification statement.
   2. (B) If an elections official has a telephone number or email address on file for a voter whose signature does not compare pursuant to subdivision (c), the elections official shall notify the voter by telephone, a text message, or email of the opportunity to verify the voter’s signature. If an elections official calls the voter and the voter does not answer, the elections official shall attempt to leave a voicemail message.
   3. (C) Unless required pursuant to Section 3026, the elections official may send additional written notices to a voter identified pursuant to subdivision (c), and may also notify the voter in person or by other means of the opportunity to verify the voter’s signature.
   4. (D) Unless required pursuant to Section 3026, the elections official may use any information in a county’s election management system, or otherwise in the elections official’s possession, for the purpose of notifying the voter of the opportunity to verify the voter’s signature.
   5. (E) If it is impracticable under the circumstances for the elections official to send the notice described in subparagraph (A) on or before the next business day, including in the event of technological failure, the elections official shall send the notice as soon as practicable, but not later than the applicable notification deadline after the election.

2. (2) The notice and instructions shall be in substantially the following form. The elections official shall insert the date of the applicable receipt deadline after the election where indicated on the form.
