The Telephone Consumer Protection Act restricts calls and texts made using an automatic telephone dialing system or an artificial or prerecorded voice, and separately restricts telemarketing calls to numbers on the National Do-Not-Call Registry. The statute assigns a fixed dollar amount per violation regardless of actual harm, and that amount can be trebled for violations found to be willful or knowing, which means the core factual dispute -- did this particular call or text meet the statutory definition, and did the defendant have valid consent -- gets multiplied across every call in the calling campaign rather than resolved once. The statute also creates a private right of action, so an individual consumer can sue directly without waiting on a regulator, which is part of why TCPA litigation volume has grown steadily even as the underlying legal standards have narrowed.

Consent sits at the center of almost every TCPA case. Ordinary informational calls generally require prior express consent, while telemarketing calls and prerecorded telemarketing messages require the stricter prior express written consent, and a called party can revoke consent at any time through a clearly expressed request, after which continued calling becomes its own violation. The statutory definition of an autodialer has itself been narrowed by courts to require the capacity to generate numbers using a random or sequential number generator, so plaintiffs and defendants frequently fight over the technical architecture of the dialing platform before ever reaching the consent question. Because a single campaign can generate thousands of calls, class certification is often the real battleground, since it determines whether the case is worth a few thousand dollars or scales into a company-threatening judgment.

Per-violation statutory damages mean the exposure math in a TCPA case is almost entirely a function of call volume and the willfulness multiplier, not the harm to any individual plaintiff, which is why these cases resolve overwhelmingly through negotiated class settlements rather than trial. Consent -- whether it existed, whether it was ever revoked, and whether the defendant's records can prove either -- is where most of the real fact-finding happens, since the legal standard itself is largely settled. The scope-of-autodialer question and the class-certification decision function as gating events: a narrow autodialer ruling or a denied certification motion can collapse a company-threatening claim down to an individual nuisance suit almost overnight.
