S.D. Codified Laws § 54-15-14

No consumer reporting agency is required to place a security freeze in a consumer credit report if the consumer reporting agency acts only as a reseller of credit information by assembling and merging information contained in the data base of another consumer reporting agency or multiple consumer reporting agencies, and does not maintain a permanent data base of credit information from which new consumer credit reports are produced. However, a consumer reporting agency shall honor any security freeze placed on a consumer credit report by another consumer reporting agency.
