The do-not-call registry is the product of concerted, measured efforts by Congress and two agencies over more than a decade. When Congress passed the Telephone Consumer Protection Act (“TCPA”), it recognized that the nature and volume of unwanted telemarketing had created significant intrusions into residential privacy that individuals were powerless to combat. Congress authorized creation of a do-not-call registry at that time, but gave the Federal Communications Commission (“FCC”) latitude to consider other options, such as requiring telemarketers to keep their own do-not-call lists.
