(a) If the elector provides a name, date of birth, and prior address and the county clerk and recorder can match the name, date of birth, and prior address to the elector's prior registration record, the elector's registration record shall be transferred from the old county.
(b) If the elector provides a name and date of birth but does not provide a prior address, the elector's registration record shall be transferred from the old county only if:
(I) The elector provides a driver's license or identification card number, and the county clerk and recorder of the new county of residence can match the name, date of birth, and driver's license or identification card number to the elector's prior registration record; or
(II) The elector provides a social security number, and the county clerk and recorder of the new county of residence can match the name, date of birth, and social security number to the elector's prior registration record.
(c) If the elector does not provide a prior address, driver's license number, or social security number, the registration record shall not be transferred from the old county unless the elector submits additional information that complies with the requirements of this subsection (1). The county clerk and recorder of the county of prior residence may send notice to the elector by forwardable mail to the elector's address of record. Any such notice shall have a returnable portion that has the return postage prepaid and is preaddressed to the sending county clerk and recorder, and shall include an area for the elector to indicate if the elector has moved to another county and wishes to have his or her registration record transferred from the old county.
(2) If a county clerk and recorder receives a notice from the secretary of state or from an election official in another state that the elector has registered to vote in another state, the county clerk and recorder of the county of prior residence shall cancel the registration record if the name and birth date or the name and social security number of the elector match.
