Starting in 2026, auditors use mail to check voter registrations

County auditors send a confirmation letter or postcard when an acknowledgement notice is returned undelivered. This applies when the acknowledgement notice sent under § 12-4-5.3 is returned to the county auditor as undeliverable. The mailing lists the voter's registration information and says registration may be canceled if the voter does not respond. If the voter reports a new address in another South Dakota county or another state, the returned letter or card serves as authorization to cancel the registration. Voters have 30 days from the postmark to sign and return correct information or send corrected information. The law takes effect December 1, 2026.
