Will signing up for the Do Not Call Registry stop all telemarketing calls?

Placing your number on the Registry will stop most, but not all, telemarketing calls. Some businesses and organizations are exempt from the national Registry and still can call you. Those exemptions cover companies with which you have an existing business relationship, as well as tax-exempt nonprofit organizations, political organizations and polling firms. While state law exempts newspaper publishers from complying with the Do Not Call Registry, federal law does not. Therefore, newspapers must also comply with the Registry.
