While more than 150 million numbers have been added to the National Do Not Call Registry, the Better Business Bureau continues to get calls from people who aren't aware of this resource.
The registry began in 2003 to give consumers a choice on telemarketing calls. It's managed by the Federal Trade Commission (FTC). If you decide to register your number, telemarketers covered by the registry have 31 days to comply and stop calling you. If they continue to call you, they can be fined thousands of dollars.
