Telephone Consumer Protection Act of 1991

The TCPA restricts autodialed and prerecorded-voice calls and texts to cell phones without prior express consent, prerecorded calls to residential lines, and unsolicited faxes, and underpins the National Do-Not-Call Registry rules. FCC rules effective April 11, 2025 require honoring consent revocations by any reasonable means within 10 business days; the 'revoke-all' portion was delayed to January 31, 2027. The FCC's 2023 'one-to-one consent' rule was vacated by the Eleventh Circuit and removed in August 2025.
