If you are unable to cast a ballot on Election Day, you may be eligible to vote by absentee ballot. To vote by absentee ballot, a voter must request an absentee ballot application from the county in which they reside.  

Registered voters can vote in-person prior to election day by bringing along a valid photo identification card (ID), such as a driver’s license, tribal photo ID, local high school ID, college or university ID from a South Dakota institution, or a passport or other federal government-issued ID. If a voter does not have a photo ID, they must sign a personal identification affidavit and will vote on a regular ballot.
