What is TCPA (Telephone Consumer Protection Act)?
The TCPA is the US federal law restricting autodialed, prerecorded and artificial-voice calls and texts. Since a 2024 FCC ruling, AI-generated voices count as artificial voices, so marketing calls generally need prior express written consent.
Also known as: Telephone Consumer Protection Act, US robocall law
What it requires
The TCPA, with FCC rules in 47 CFR 64.1200, limits calls made with an automatic dialer or an artificial or prerecorded voice to mobile phones without consent. Telemarketing calls need prior express written consent; informational calls need prior express consent. Calls must identify the caller, offer an opt-out and respect the National Do Not Call Registry and calling-hour limits. Damages are statutory, per call, which is why class actions are common.
AI voices
In February 2024 the FCC ruled that calls using AI-generated voices are 'artificial' under the TCPA, so the consent requirement applies to them. The FCC's separate one-to-one consent rule for lead-generation was vacated by the Eleventh Circuit in January 2025, so the older consent standards remain the reference point.
Common mistake
Treating bought lead lists as consent. Consent must be traceable to the person, for that kind of call, and in writing for marketing. Keep the consent record, timestamp and wording alongside the number, and honour revocation promptly.
