*Independent (IND) / No Party Affiliation (NPA) - South Dakota does not have an Independent Party. If a person completes a registration card to change that person's name, address, phone number, or email address, and leaves the field for party affiliation blank, the county auditor must list the person's party affiliation as the most recent party affiliation registered for that person. If a person completes a registration card to register to vote for the first time in the state and leaves the field for party affiliation blank, the county auditor must register that person's party affiliation as no party affiliation.
**OTHER – This category is for voters who write any other political party on their voter registration form that is not currently a recognized political party in South Dakota.
