South Dakota consumers may sign up to stop most telemarketing calls. The sign-up is free and consumers have two ways to register their home telephone and personal cell phone numbers:
1. Call 1-888-382-1222 from the home or personal cell phone you wish to be registered; or
2. Register via Internet at www.donotcall.gov for wireline and/or wireless phones. Consumers can register just once to be covered by both the national and state Do Not Call lists. South Dakotans can register complaints with the PUC at 1-800-332-1782.
