S.D. Codified Laws § 12-19-2.4
If any voter who had previously filed an application or request for an absentee ballot submits another application or request for the same election with an updated address, the county auditor shall send an absentee ballot to the new address. If any voter who had previously filed an application or request for absentee ballot appears at the county auditor's office, the voter may complete another application and be allowed to vote an absentee ballot. If any voter who filed an application or request for absentee ballot notifies the county auditor that the voter never received that ballot, the voter may request that another ballot be sent to the same address. The provisions of this section only apply to a person who has not voted or returned an absentee ballot.
