Is AI Cold Calling Legal? TCPA and AI Voice Rules in 2026

Short answer: AI calling is legal in most countries, but it is regulated. In the US, the FCC treats AI-generated voices as "artificial" voices under the Telephone Consumer Protection Act (TCPA), so the same consent rules as robocalls apply: you generally need the person's prior express consent to call a mobile number, and prior express written consent for marketing calls. Calling leads who asked to be contacted, at reasonable hours, with an honest AI disclosure and a working opt-out, keeps you on the right side of the rules.

This article is general information, not legal advice. Laws change and depend on where you and your leads are. Last reviewed: October 2026.

What changed: AI voices are "artificial voices" under the TCPA

In February 2024 the Federal Communications Commission issued a Declaratory Ruling confirming that calls using AI-generated or cloned voices count as calls with an "artificial or prerecorded voice" under the TCPA. There's no special "AI exemption": an AI voice agent is treated like a robocall for consent purposes, even when it holds a real two-way conversation.

In practice, under the TCPA:

• Calls to mobile phones with an artificial voice need the person's prior express consent, for any purpose (except emergencies).
• Marketing or sales calls with an artificial voice need prior express written consent: a signed agreement (an online form with a clear checkbox counts under the E-SIGN Act) that names your business and says the person agrees to receive marketing calls using an artificial or prerecorded voice.
• Residential landlines follow the same logic for telemarketing calls.

Penalties are why this matters: the TCPA allows $500 per call in statutory damages, up to $1,500 per call when the violation is willful, and class actions are common.

What counts as consent?

Consent should be given by the person, before the call, for the kind of call you make. Good examples:

• A lead fills in your "Book a demo" or "Get a quote" form and ticks a box like: "I agree that [Company] may call me at this number, including with an automated or AI voice, about my request. Consent isn't required to buy."
• A customer signs up for your product and agrees to be called about onboarding.
• Someone asks you to call them back.

Bad examples: purchased lists, scraped numbers, or "they're on LinkedIn, so it's public". A number being findable is not consent.

Keep a record of each consent: the form, the wording, the date, time and IP address. If someone ever complains, that record is your defense.

B2B calls: are business numbers exempt?

Partly, and less than most people think. The National Do Not Call Registry protects residential subscribers, and calls to business landlines are generally outside the TCPA's residential telemarketing rules. But the TCPA's consent requirement for artificial-voice calls to mobile phones applies regardless of whether the person uses the phone for work. Most B2B leads give a mobile number. Treat B2B AI calls to mobiles exactly like consumer calls: get consent.

The other US rules to follow

• Calling hours: telemarketing calls only between 8 a.m. and 9 p.m. in the lead's local time. Some states are stricter.
• Do-not-call: scrub against the National DNC Registry for consumer telemarketing (unless you have consent or an existing business relationship), and keep your own internal do-not-call list. Honor every "don't call me again" immediately.
• Identification: say who is calling and on whose behalf, and give a way to opt out.
• Telemarketing Sales Rule (FTC): prerecorded or artificial-voice sales calls need the person's express written agreement, and the call must offer an opt-out.
• State "mini-TCPA" laws: states like Florida and Oklahoma have their own consent, timing and frequency rules for automated sales calls. If you call nationwide, follow the strictest ones.
• Call recording: AI calls are recorded and transcribed. Some states (such as California) require everyone on the call to consent to recording; an early disclosure covers this.

About "one-to-one consent": the FCC adopted a rule in 2023 requiring consent to be given to one seller at a time, but a federal appeals court vacated it in January 2025. Consent naming your business clearly is still the safest practice.

Outside the US

• European Union: the ePrivacy rules require prior consent for automated calling systems, and the GDPR applies to the lead's personal data (you need a legal basis, transparency and a way to object). Several countries add national do-not-call registers.
• United Kingdom: under PECR, automated marketing calls need prior consent. Live sales calls must also screen against the TPS/CTPS registers.
• Canada: the CRTC's Unsolicited Telecommunications Rules restrict automatic dialing-announcing devices for sales calls without express consent, and telemarketing has set calling hours and a national DNCL.

A simple compliance checklist for AI calling

1. Only call leads who asked to be contacted, and keep proof of their consent.
2. Use clear consent wording on every form that feeds your AI agent.
3. Call within allowed hours in the lead's time zone.
4. Have the agent identify your business and say it's an AI when asked.
5. Honor opt-outs instantly and keep an internal do-not-call list.
6. Scrub consumer lists against do-not-call registries.
7. Review transcripts regularly to check what your agent says.
8. Ask a lawyer to review your setup if you call consumers at scale or in several countries.

How CallBooker helps you stay compliant

CallBooker is built for calling leads who asked to hear from you, and it bakes the basics in:

• A calling agreement every account accepts before its first call, covering consent, do-not-call and calling laws.
• Honest AI disclosure: agents say they're an AI assistant whenever someone asks, and never claim to be human.
• Automatic do-not-call: when a lead asks not to be called again, the agent marks them "do not call" and CallBooker refuses to call that number again, in single calls and campaigns.
• Full transcripts of every call, so you can check what was said.
• Your own phone numbers through your Twilio account, so caller ID always shows who's really calling.

The best use of AI calling is also the most compliant one: calling people seconds after they ask you to. Want to hear what that sounds like? Get a call from our AI, or read our Terms for the full calling rules.
