How to Block Telemarketing Calls

If you're tired of receiving unwanted telemarketing phone calls, here are three different ways to help you stop them.

1. The National Do Not Call Registry

The Do Not Call Registry lets you register your home or mobile phone number for free. It's backed by the U.S. Federal Trade Commission. And the registration never expires.

Go to and click Register Your Phone. You can register up to three different phone numbers. Enter your email address, then reply to the verification email when you receive it. To register by phone, you must call from the number you want registered: Consumers may call 1-888-382-1222 or for TTY call 1-866-290-4236.

The Registry will not block calls from charities, political calls, surveys and information calls. It will not block calls from a company or organization that has a relationship with you. To stop calls from any of these companies or groups, you must ask them to take you off their list. They are required to honor your request.
