Is there a legal requirement to disclose AI use on phone calls?

There is no single federal law in the United States that explicitly requires businesses to disclose that a caller is speaking with an AI, but several state laws and general consumer protection principles create real legal exposure if you don't. California's Bolden Act (AB 1826, enacted in 2019) is the most notable example — it prohibits bots from using deceptive means to make a person believe they're communicating with a human, specifically in commercial contexts. If a caller sincerely asks whether they're speaking with a bot or a human, California law requires an honest answer. Other states are moving in similar directions as AI becomes more common in customer-facing roles.

Beyond state-specific statutes, the FTC has broad authority to pursue businesses that engage in deceptive practices, and misrepresenting an AI as a human could reasonably fall under that umbrella. The TCPA also governs automated calls in specific ways, particularly around consent and prerecorded messages, which can overlap with AI voice systems depending on how they're deployed. These aren't obscure edge cases — they're real compliance considerations that businesses using AI phone systems should understand before going live.

The practical takeaway for most businesses is straightforward: train your AI system to identify itself honestly if asked, and consider having it introduce itself as an AI assistant or virtual receptionist at the start of the call. This isn't just a legal precaution — most callers accept AI receptionists without issue when they know what they're dealing with upfront. The backlash usually comes from feeling deceived, not from speaking with automation itself. A transparent setup protects you legally and tends to build more trust with customers.
