Answer:
Do Not Call: Consumer Information
The Do Not Call Law was implemented in response to consumers' concerns regarding unwanted telemarketing calls.
The National Do Not Call Registry, under the joint jurisdiction of the Federal Communications Commission and the Federal Trade Commission was implemented to assist consumers. The National Do Not Call Registry gives you a choice about whether to receive telemarketing calls at home. Most telemarketers should not call your number once it has been on the registry for 31 days. To learn more about who may or may not call, review these Frequently Asked Questions. You can file a complaint if you receive unwanted calls from telemarketers to which the Do Not Call Registry applies.
The Federal Trade Commission (FTC) can add you to the National Do Not Call Registry online, or you can call 1-888-382-1222 to register. It is free to register your home or mobile phone.
