If you are receiving unsolicited telemarketing calls the Do Not Call list can reduce these. Registration is free and covers landline and wireless phone numbers.
Michigan has adopted the Federal Trade Commission's Do Not Call Registry as the state's Do Not Call list. By signing up for the Federal Registry you will automatically be placed on Michigan's Do Not Call list as well. Registration is free and does not expire. Once registered, unwanted sales calls should stop within 31 days, however some telemarketing calls are still allowed under exemptions in state law and federal regulations.
