Are AI voice agents legal? Yes. A business in Nevada, California, or Arizona can use an AI voice agent to answer calls, book appointments, and follow up with customers. The rules depend on which way the call goes, whether it is recorded, and where the caller is.

The Short Answer
- AI answering inbound calls: Generally allowed. Federal robocall consent rules target calls you make. State recording laws still apply.
- AI making outbound calls: The FCC treats AI-generated voices as artificial voices under the Telephone Consumer Protection Act (TCPA). You need the person’s prior express consent. Sales calls need prior express written consent.
- Recording: Nevada and California require consent from everyone on a phone call. Arizona requires one party. Announce recording on every call.
- Texting: Get opt-in first, honor STOP, and register your business texting with carriers through A2P 10DLC.
Inbound vs. Outbound: The Distinction That Matters Most
Most confusion about AI phone call laws comes from mixing up two uses. An AI receptionist that answers your line is one thing. An AI voice that dials a list is another.
Outbound Calls: The FCC’s 2024 Ruling
On February 2, 2024, the Federal Communications Commission adopted a Declaratory Ruling (FCC 24-17), released February 8, 2024. It confirms that the TCPA’s limits on “artificial or prerecorded voice” calls cover AI technologies that generate human voices, including voice cloning.
In practice, before an AI voice calls someone, you need that person’s prior express consent, unless the call is for an emergency or fits an FCC exemption. If the call includes an advertisement or telemarketing, the FCC’s rules require prior express written consent under 47 CFR 64.1200(a)(2) and (a)(3).
The ruling also says the TCPA allows no carve-out for technology that claims to be the equivalent of a live agent.
The same federal rule says artificial-voice messages must identify the business at the start and give a callback number. Telemarketing messages must also offer an automated opt-out. Telephone solicitations to residential subscribers can’t go out before 8 a.m. or after 9 p.m. local time, and National Do Not Call Registry numbers are protected.
Inbound Calls: When the Customer Calls You
The TCPA’s artificial-voice restrictions are written around making or initiating calls (47 U.S.C. 227(b)(1)). The FCC’s 2024 ruling addresses calls a business initiates, not AI answering calls customers place.
That doesn’t make an AI receptionist rule-free. Most AI voice agents record or transcribe calls, so follow state recording law. If the AI later calls or texts that customer back, that is outbound again.
Two Points Still in Motion
First, on June 20, 2025, the U.S. Supreme Court held in McLaughlin Chiropractic Associates v. McKesson Corp. that federal district courts are not bound by the FCC’s interpretation of the TCPA in enforcement cases. Following the FCC ruling is still the safer path.
Second, in August 2024 the FCC proposed rules (FCC 24-84) that would require callers to disclose AI use when getting consent and at the start of AI-generated calls. We found no final version adopted as of this writing.
State-by-State Rules: Nevada, California, and Arizona
Call recording consent in Nevada, California, and Arizona is where most businesses trip up.
| State | Phone call recording consent | AI or bot disclosure law | Notes |
|---|---|---|---|
| Nevada | All parties. NRS 200.620, as read by the Nevada Supreme Court in Lane v. Allstate (1998). | No general AI disclosure law for business calls or chat found. AB 406 (2025) limits AI in mental and behavioral health care. | NRS 200.620 does not reach recordings made outside Nevada (Ditech v. Buckles, 2017). |
| California | All parties. Penal Code 632 (confidential communications) and 632.7 (calls involving cell or cordless phones). | Bus. and Prof. Code 17941 (online bots). Pub. Util. Code 2874 (artificial voice notice for automatic dialing-announcing devices, from Jan. 1, 2025). | Private suits can seek $5,000 per violation or triple damages, whichever is greater (Penal Code 637.2). |
| Arizona | One party. ARS 13-3005 and ARS 13-3012(9). | No AI-specific disclosure statute for business calls or chat found. | If the caller is in California, California’s all-party rule may apply. |
Nevada
NRS 200.620 bars intercepting a wire communication unless one party consents and an emergency makes getting a court order impractical. In Lane v. Allstate Insurance Co. (December 8, 1998), the Nevada Supreme Court held that taping a phone call counts as an interception and that one party’s consent is not enough. The court restated that reading in Ditech Financial LLC v. Buckles (2017).
Willful violations are a category D felony with civil damages under NRS 200.690. In-person conversations fall under NRS 200.650, which allows recording with one participant’s authorization. For a Las Vegas business running an AI phone line, announce the recording.
California
Two recording rules apply. Penal Code 632 bans recording a confidential communication without the consent of all parties. Penal Code 632.7 bans intentionally recording calls involving a cell or cordless phone without all parties’ consent, confidential or not. Most customers call from cell phones, so plan for all-party consent. In Kearney v. Salomon Smith Barney (2006), the California Supreme Court applied California’s rule to an out-of-state firm recording calls with California clients.
California’s bot disclosure law, SB 1001 (Bus. and Prof. Code 17940 to 17943, operative July 1, 2019), makes it unlawful to use a bot to talk with someone in California online with intent to mislead them about its artificial identity, in order to push a sale or influence an election vote. A clear and conspicuous bot disclosure avoids liability.
The law defines “online” as public-facing websites, web applications, and digital applications. A website chat agent fits. Whether a phone call counts as “online” is unclear, and we found no court ruling on it. Disclose on the phone anyway.
AB 2905 amended Public Utilities Code 2874, effective January 1, 2025. Calls placed with an automatic dialing-announcing device must say if the prerecorded message uses an artificial voice, meaning one generated or significantly altered using AI. Whether a conversational AI agent counts as such a device is unsettled.
SB 243, signed October 13, 2025, regulates companion chatbots but expressly excludes bots used only for customer service or business operations. Businesses in Southern California should keep watching Sacramento for new AI bills.
Arizona
ARS 13-3005 makes unauthorized interception a felony. ARS 13-3012(9) exempts interceptions made with the consent of a party to the communication. That makes Arizona a one-party consent state.
The catch is your callers. A Sedona lodge or Flagstaff contractor may take calls from people in California. Under Kearney, California’s all-party rule may reach those calls. For Northern Arizona businesses, a recording announcement is still the smart default. We found no Arizona statute that specifically requires AI disclosure on business calls or chat.
Texting Rules for AI Text Agents
In Campbell-Ewald Co. v. Gomez (January 20, 2016), the Supreme Court noted that a text message to a cell phone qualifies as a “call” under the TCPA.
- Consent: Get opt-in before you text. The CTIA Messaging Principles that carriers follow call for consent to message and express written consent for marketing messages.
- Do Not Call: Federal Do Not Call rules apply to telemarketing texts sent to wireless numbers (47 CFR 64.1200(e)).
- STOP means stop: Under 47 CFR 64.1200(a)(10), a reply of “stop,” “quit,” “end,” “revoke,” “opt out,” “cancel,” or “unsubscribe” revokes consent. Honor it within 10 business days. One non-marketing confirmation text is allowed.
- A2P 10DLC: U.S. carriers require businesses texting from standard 10-digit numbers through software to register their brand and campaign. Twilio’s documentation notes unregistered traffic faces extra carrier fees and heavier filtering.
AI Receptionist Legal Checklist
Use this list before you launch. It is a starting point, not a guarantee of compliance.
- Disclose AI at the start. “Hi, you’ve reached the virtual assistant for [Business Name].” One sentence builds trust and addresses California’s bot law.
- Announce recording before the conversation. This addresses the all-party rules in Nevada and California.
- Offer a human handoff. Let callers reach a person, or leave a message for one.
- Capture consent for outbound calls and texts. Use written consent for marketing. Save the date, source, and wording.
- Identify your business on outbound AI calls. State your registered business name up front and give a callback number.
- Honor STOP and do-not-call requests. Build the opt-out into the agent itself.
- Keep records. Store consent logs, opt-out lists, transcripts, and 10DLC registration details.
- Never let the agent pose as a human. If a caller asks, the agent says it is AI.
- Flag regulated industries. Healthcare and finance carry extra rules. Nevada’s AB 406, for example, restricts AI that presents itself as providing mental or behavioral health care.
How MCNM Builds These Guardrails In
MCNM builds AI voice receptionists, chat and text agents, review agents, and content agents. Our agents identify themselves as AI assistants and hand off to a human. Texts go only to contacts who opted in, and every message honors STOP.
We build those guardrails into every setup and connect them to your marketing automation and CRM so consent and opt-out records stay in one place. We don’t give legal advice or promise compliance on your behalf. Confirm your requirements with your attorney.
Frequently Asked Questions
Yes, in general. We found no Nevada law that bans AI receptionists. The bigger issue is recording. The Nevada Supreme Court reads NRS 200.620 to require consent from all parties to record a phone call. Announce the recording at the start of every call, and talk to a Nevada attorney about your setup.
It depends on the channel and the state. California bans using an online bot to mislead people about its artificial identity to drive a sale, and disclosure avoids liability. Whether that covers phone calls is unclear. Disclosing AI at the start of every call and chat is the simplest way to reduce risk.
For outbound calls, yes. In February 2024 the FCC confirmed that AI-generated voices are artificial voices under the TCPA. Calls using them need prior express consent, and telemarketing calls need prior express written consent. The FCC ruling addresses calls businesses make, not AI answering calls that customers place.
Only with consent from everyone on the call. Penal Code 632 covers confidential communications, and Penal Code 632.7 covers calls involving cell or cordless phones. People harmed can sue for $5,000 per violation or triple damages, whichever is greater. Have your AI agent announce recording before the conversation begins.
If your AI agent texts U.S. customers from a standard 10-digit business number through software, U.S. carriers expect A2P 10DLC brand and campaign registration. Unregistered traffic can face extra fees and heavier filtering. Your texting provider usually handles the registration steps, but you supply the business details and opt-in process.
The Bottom Line
AI voice agents are legal in Nevada, California, and Arizona when you use them with care. Outbound AI calls and texts need consent. Recording needs an announcement. And an honest “I’m an AI assistant” solves more problems than it creates.
