⚠

Mini-TCPA State — Cal. Pub. Util. Code §§ 2871-2876; Cal. Bus. & Prof. Code §§ 17590-17594

California has enacted a state-level TCPA that goes beyond federal requirements. Federal compliance alone is not enough for AI Voice operations here.

Consent Requirements

Consent LevelWritten Consent Required

Federal one-to-one consent rule: vacated

The FCC rule requiring consent to name each seller was vacated by the Eleventh Circuit on January 24, 2025 and never took effect. Source

Checkbox ConsentValid

StatuteCal. Pub. Util. Code § 2874 (as amended by AB 2905); Cal. Penal Code § 632; 47 U.S.C. § 227

Highest complexity channel in California. AI voice agents trigger at least four overlapping regulatory frameworks: (1) ADAD — live intro required, consent to hear message, 9AM-9PM hours; (2) AB 2905 — must disclose AI voice at call start, $5,000/violation/day; (3) CIPA — if the call is recorded or monitored, all-party consent required, $5,000 per violation; (4) Federal TCPA — prior express written consent for marketing calls using automated systems. FTC impersonation rules add additional liability if AI voice mimics a real person without disclosure. California is the most hostile jurisdiction in the US for AI voice telemarketing deployment.
