The National Do-Not-Call Registry. 

The Federal Trade Commission established a National Do-Not-Call Registry pursuant to federal law. Consumers who wish to decrease the amount of unsolicited telemarketing calls they receive may register with the National Do-Not-Call Registry at: or by phone 1-888-382-1222.   

There are two do not call lists available to Wyoming residents. The Federal Trade Commission's National Do-Not-Call Registry and the Direct Marketing Association, Inc.'s Telephone Preference Service. Wyoming residents may sign up for both lists.
