South Dakota Statutes § 12-4-19 Address verification request-Confirmation mailing-Exception

Any voter in the active registration file who has failed to vote, has not updated the voter's registration information, and has not replied to a confirmation mailing at least once during the last preceding four consecutive years shall be sent a nonforwardable return-if-undeliverable address verification request. If the request is undeliverable then a confirmation mailing prescribed by the State Board of Elections shall be sent. If a county auditor has determined through a national change of address licensee of the United States Postal Service that the address of a voter who is to be sent an address verification request has changed, the confirmation mailing may be omitted. This process shall be performed by each county auditor from January first to November fifteenth, inclusive, of each odd-numbered year.
