History of the TCPA, 1991 to 2025

Before 1991

By the late 1980s, automated dialing equipment could place thousands of calls an hour and play a recorded message to whoever answered. Fax machines were receiving unsolicited advertisements that consumed the recipient's paper and toner. Several states passed laws against both, but calls cross state lines and state law could not reach the caller in the next state. Congress held hearings, and the record it built described consumers who had been called at dinner, in hospital rooms, and on emergency lines by machines.

Enactment, 1991

The Telephone Consumer Protection Act of 1991 was sponsored in the Senate by Ernest Hollings of South Carolina and signed by President George H. W. Bush on 20 December 1991. It was added to the Communications Act of 1934 as section 227, now at 47 U.S.C. § 227. Congress's findings, printed with the Act, described automated and prerecorded calls as a nuisance and an invasion of privacy and said the only effective means of protecting consumers was to ban them in most forms.

The original Act did four main things. It prohibited calls to cell phones, emergency lines and hospital rooms using an automatic telephone dialing system or an artificial or prerecorded voice without consent. It prohibited prerecorded telemarketing calls to residential lines without consent. It banned unsolicited fax advertisements. And it directed the FCC to consider rules protecting residential subscribers from unwanted telephone solicitations, which became the do-not-call provisions. It gave the person called a private right of action for $500 per violation, with trebling for willful or knowing conduct.

First rules, 1992

The FCC adopted its first implementing rules in 1992, now at 47 C.F.R. § 64.1200. They set the 8am to 9pm calling window for telephone solicitations, required callers to identify themselves, and required each company to keep its own do-not-call list of people who asked not to be called. The 1992 rules also recognised an established business relationship as a form of consent for prerecorded calls to residential lines, an exemption the FCC would later remove.

The National Do Not Call Registry, 2003

Congress authorised a national registry in the Do-Not-Call Implementation Act of 2003. The Federal Trade Commission opened the National Do Not Call Registry in June 2003 under its Telemarketing Sales Rule, and the FCC adopted parallel rules under the TCPA the same year so that both agencies' rules covered the same registry. Enforcement began in October 2003. The 2003 FCC order also addressed predictive dialers, concluding that equipment which dialed from a list without human intervention fell within the autodialer definition, a position that would be litigated for the next eighteen years. In 2007 Congress passed the Do-Not-Call Improvement Act, which made registrations permanent rather than expiring after five years.

Faxes and caller ID, 2005 to 2010

The Junk Fax Prevention Act of 2005 amended § 227 to codify an established business relationship exemption for fax advertisements and to require an opt-out notice on every fax sent under it. The Truth in Caller ID Act of 2009, signed in December 2010, added § 227(e), prohibiting the transmission of misleading or inaccurate caller ID information with intent to defraud, cause harm or wrongfully obtain anything of value.

Prior express written consent, 2012

In February 2012 the FCC adopted the rule that defines modern telemarketing compliance. For telemarketing calls using an autodialer or prerecorded voice to a cell phone, and for prerecorded telemarketing calls to a residential line, the caller must have the called party's prior express written consent. The order also removed the established business relationship exemption for prerecorded telemarketing calls to residences and required an automated opt-out mechanism in prerecorded telemarketing calls. The written consent requirement took effect on 16 October 2013.

The 2015 omnibus and its undoing

In July 2015 the FCC issued a long declaratory ruling resolving some two dozen petitions. On autodialers it concluded that equipment with the "capacity" to dial random or sequential numbers was covered even if that capacity was not used, a reading that swept in most modern dialers and smartphones. It also addressed reassigned numbers, consent revocation by any reasonable means, and text messages. In 2018 the D.C. Circuit in ACA International v. FCC set aside the autodialer and reassigned-number portions as arbitrary, which left the courts of appeals to read the statutory definition for themselves and produced a circuit split.

Separately, the Bipartisan Budget Act of 2015 added an exception for calls made solely to collect a debt owed to or guaranteed by the United States. That exception would be the subject of the Supreme Court's 2020 decision.

The TRACED Act, 2019

The Pallone-Thune Telephone Robocall Abuse Criminal Enforcement and Deterrence Act, signed on 30 December 2019, was aimed at illegal robocalls rather than at marketers who make legitimate calls badly. It required voice providers to implement the STIR/SHAKEN caller authentication framework, lengthened the FCC's enforcement window and added a forfeiture penalty for intentional violations. Separately, the reassigned numbers database the FCC had ordered in 2018 went live in 2021, giving callers a way to check whether a number had changed hands.

The Supreme Court, 2020 and 2021

In Barr v. American Association of Political Consultants (2020), the Court held that the 2015 government-debt exception was a content-based restriction on speech that violated the First Amendment, and severed it, leaving the rest of the robocall restriction in force. In Facebook, Inc. v. Duguid, 592 U.S. 395 (2021), the Court resolved the circuit split on autodialers: to qualify as an automatic telephone dialing system, a device must have the capacity to use a random or sequential number generator to store or produce telephone numbers. List-based dialers that do not use such a generator are outside the definition.

The same year Florida amended its Telephone Solicitation Act to add a private right of action and an autodialer provision broader than the federal one, the first of a series of state "mini-TCPA" statutes that responded to Duguid.

2023 to 2025

In December 2023 the FCC adopted a rule requiring that prior express written consent obtained through a lead-generation website authorise one identified seller at a time, the "one-to-one" consent rule, with an effective date of 27 January 2025. On 24 January 2025, the Eleventh Circuit vacated it in Insurance Marketing Coalition Ltd. v. FCC, holding that the Commission had exceeded its authority by adding requirements beyond the statute's "prior express consent".

In February 2024 the FCC issued a declaratory ruling that calls using AI-generated voices, including voice cloning, are calls using an "artificial" voice under § 227(b) and therefore require the same consent as prerecorded calls. In the same month it adopted rules confirming that consumers may revoke consent by any reasonable means and requiring callers to honour a revocation within ten business days; those rules took effect in April 2025.

In June 2025 the Supreme Court decided McLaughlin Chiropractic Associates v. McKesson Corp., holding that district courts in TCPA enforcement proceedings are not bound by the FCC's interpretations of the statute and must determine its meaning for themselves under ordinary principles of statutory interpretation. The practical result is that FCC rulings remain persuasive but can be challenged in private litigation.
