A national "do not call" list has been established by the Federal Trade Commission. Registration for the "do not call" list began in June. Over 635,000 phone numbers have already been registered. If you are interested in registering your telephone number or mobile number, go to www.ftc.gov and follow the link to the "do not call" list. Traffic is extremely high, so it may take a while for you to be able to log on to the site and get registered. Be patient.
