Elec. Code, § 3019.7

(a) The Secretary of State shall maintain a system to allow a vote by mail voter to track the voter’s vote by mail ballot through the mail system and as the vote by mail ballot is processed by the county elections official. A county elections official shall use this system unless the county makes available to voters a different vote by mail ballot tracking system that meets or exceeds the level of service provided by the Secretary of State’s system. The system shall, at a minimum, be accessible to voters with disabilities and allow a voter to register to receive information via email or text message from the county elections official about the status of the voter’s vote by mail ballot, including all of the following information:

(1) A notification when the ballot has been delivered by the county elections official to the United States Postal Service.

(2) A notification of the date, based on information from the United States Postal Service, that the voter’s ballot is expected to be delivered to the voter.

(3) A notification if the voter’s ballot is returned as undeliverable to the county elections official by the United States Postal Service.

(4) A notification when the voter’s completed ballot has been received by the county elections official.

(5) A notification that the voter’s completed ballot has been counted, or, if the ballot cannot be counted, a notification of the reason why the ballot could not be counted and instructions of any steps that the voter can take in order to have the ballot counted. If the ballot cannot be counted because the voter’s signature did not compare or the identification envelope is missing a signature, as described in subdivisions (c) and (e) of Section 3019, and the voter has opted in to receive notifications by text or email, the notification shall include an internet website link to the required form for verifying or providing a signature, as applicable, and instructions for completion.

(6) A reminder of the deadline for the voter to return the voter’s ballot if the county elections official has not received a voter’s completed ballot by specified dates as determined by the county elections official.

(b) The Secretary of State shall make the system maintained pursuant to subdivision (a) available for use by each county. A county elections official may use the system for the purpose of complying with Section 3019.5.
