Tired of sales calls?, well just register with the National Do Not Call Registry and you won’t receive another sales call for another FIVE years. Once you register both your home phones as well as cell phones, 3 at a time, you will be added into the directory after 31 days. (if you need to register more of your own numbers go back after your first round and you can still use the same email) Before your number can be registered you will need to verify your account by clicking on a special link provided to you through the email you entered. This service is run by the Federal Trade Commission (FTC) and put into service on January 1, 2005. After signing up if you do wish to start recieving sales calls again you will have to delete yourself from the registry. To do so just call 1-888-382-1222 from the phone you wish to delete. After the call is complete you will be removed from the registry in another 31 days.
