Does REPEP Apply to AI Sales Calls in Mexico?

Short answer: assume yes, until your adviser tells you otherwise. REPEP, the Registro Público para Evitar Publicidad run by Mexico's consumer-protection agency PROFECO, is a free register where consumers list their phone numbers so that providers stop using them for promotional calls. Nothing we could read says an AI voice agent is treated differently from a human caller, and we could not verify how it is classified. So check REPEP, and the consent you hold, before any outbound campaign. We do not screen numbers against it for you.

What is REPEP?

REPEP is PROFECO's register for people who do not want advertising calls. As read on 25 October 2026 in press reporting and law-firm commentary (PROFECO's own site could not be opened by our tools), anyone can register a number free of charge, online or by phone; the registration does not expire; once a number is registered, providers have 30 calendar days to stop using it for promotional calls, and after that the consumer can complain to PROFECO. Its legal basis is the Federal Consumer Protection Law, the LFPC; we did not verify the article number, so we do not cite one.

What does it cover, and what does it not?

• Calls and text messages: described in reporting as covered. We could not confirm whether WhatsApp messages are covered, so do not treat them as outside the rule.
• Sectors: reports say PROFECO is not competent over calls by financial-services providers, insurers, retirement-fund managers, collection agencies, political organisations, charities and pollsters. This comes from a news report, not the law, so treat it as unverified. Other regimes may apply to those sectors.
• Inbound calls: REPEP concerns promotional contact. Answering a customer who rings you is a different matter from cold calling.

What does the product do and not do?

The product gives you tools: a do-not-contact list you keep, calling hours you set for each campaign on the called person's clock, an opening line you write and a transcript of every call. It does not screen numbers against REPEP, it does not collect or check consent, and the platform sets no calling window of its own. You are responsible for your list. We found no calling-hours rule for sales calls in the sources we could read, so set hours you would be comfortable explaining.

How should I set up an outbound campaign sensibly?

1. Start with people who asked. A customer who filled in a form asking to be called, or who left their number on WhatsApp, is a very different case from a purchased list. Keep a record of when and how they asked.
2. Check each number against REPEP before it goes into a campaign, using the register's own tools, and keep the date you checked.
3. Open honestly. The opening line is yours to write: say who is calling, from which business and why, and offer to stop.
4. Honour a "no" at once. Add the number to your do-not-contact list so the campaign never dials it again, and keep that list when you change campaigns.
5. Set hours on the called person's clock and keep them modest. Mexico spans several time zones, so a campaign to Tijuana and one to Cancún are not on the same clock.
6. Read the transcripts for the first fifty calls and fix anything the agent said that you would not say yourself.

Does the same apply to WhatsApp marketing?

WhatsApp messages sent outside the 24-hour window need an approved template, and marketing templates should go only to people who have agreed to receive them. That is also Meta's expectation of businesses. Whether REPEP reaches WhatsApp is something we could not confirm, so the safe approach is the same: consent first, a clear way to stop, and a record of both. See WhatsApp Business API.

What about the data law?

Calling people also means processing their personal data, and Mexico's private-sector data law was replaced in March 2025. Your privacy notice should say what you do with phone numbers and call recordings. We cover this in Mexico's 2025 data law and an AI voice agent.

When is an outbound agent the wrong choice?

If your list is cold, the sector you work in has its own rules (finance, insurance, collections), or you cannot show where consent came from, do not start with outbound. Answering your own inbound calls, confirming appointments and following up customers who asked to hear from you carry far less risk and usually pay back sooner. Read the official text; this is not legal advice. The Mexico page gathers the rest, and the AI receptionist page shows what inbound answering covers.
