You know the drill. You sit down to dinner with the family and – the phone rings. It’s prime time for telemarketers, because they have statistics that say you’re probably home.

Like many people, you’ve probably entered your phone number into the National Do Not Call Registry, which 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. If they do, you can file a complaint at www.donotcall.gov. You can register your home or mobile phone for free.

The National Do Not Call Registry is managed by the Federal Trade Commission, the nation’s consumer protection agency. It is enforced by the FTC, the Federal Communications Commission, and state law enforcement officials.
