Is it legal to use an AI to answer calls without disclosing it?

In most US states, using an AI to answer business calls without disclosing it is legal, but there are important exceptions depending on where your customers are located. Federal law does not currently require businesses to announce that a caller is speaking with an AI, and most states follow the same standard. However, California's BOT Disclosure Act requires disclosure when an AI is used to interact with consumers in certain contexts, and a growing number of states are moving toward similar requirements. If your business serves customers in California or other states with emerging AI transparency laws, you should consult a local attorney before deploying an undisclosed AI receptionist.

Beyond the legal question, there is also a practical one. Many businesses find that proactive disclosure actually builds trust rather than eroding it. A simple phrase like "You've reached [Business Name], I'm an AI assistant" sets honest expectations and reduces the frustration callers feel when they eventually realize they weren't speaking with a human. Customers who feel deceived are more likely to leave negative reviews or abandon the call entirely, which undermines the whole reason you deployed the AI in the first place.

It is also worth noting that call recording laws are separate from AI disclosure laws. If your AI receptionist records calls — which most do for quality and transcription purposes — you may be required to announce the recording regardless of AI disclosure rules. Two-party consent states like California, Florida, and Illinois require both parties to consent to being recorded, so a disclosure message often handles both requirements at once.
