State Do-Not-Call lists work just like the National Do-Not-Call Registry. Adding your phone numbers prevents you from receiving most telemarketing calls at home.
Several states have created the own Do-Not-Call Registries to protect consumers from unwanted telemarketing calls. This page has lists the state Do-Not-Call programs and includes the information you need to have your numbers listed with them. Many states that maintained their own Do-Not-Call registry have no merged with the National Do-Not-Call list.
