REPEP (Registro Público para Evitar Publicidad) is a free list run by PROFECO, Mexico’s consumer protection agency. If you register your number, businesses that want to sell you things by phone or text are supposed to leave you alone. It does not cover calls from banks, collectors, charities, political groups or pollsters, and it is not a tool against scams.
What is REPEP?
According to PROFECO’s own FAQ, REPEP protects consumers from unwanted advertising “mediante llamadas telefónicas y mensajes de texto”, so it covers calls and text messages. Both mobile and landline numbers can be registered. The registration does not run out: the home page says it lasts indefinitely.
It works as a list, not as a filter on your phone. Companies that advertise by phone can pay to download the lists and avoid complaints and fines, according to the same FAQ. Nothing is blocked before the call reaches you.
How do you register?
Registration is free. The FAQ says you can do it in under 60 seconds by calling from the number you want to register:
- From Mexico City, Guadalajara and Monterrey: 96 28 00 00
- From the rest of the country: 800 962 8000
- Or online, any time, on the REPEP site
You can check whether a number is registered on the site or by calling the Teléfono del Consumidor (Telcon): 5568 8722 in Mexico City and the metro area, or 800 468 8722 elsewhere, Monday to Friday, 9:00 to 18:00. You can cancel at any time.
How long until it works?
The FAQ says the number is registered the day after you sign up and takes effect within 30 calendar days (“30 días naturales”). The complaints page speaks of 30 “días hábiles” (business days) before a complaint can be processed. The two pages do not match, so the safe reading is to wait a full six weeks before you complain.
What does REPEP not cover?
PROFECO says it clearly on the home page. Calls from these callers are “no es competencia” of the agency:
| Not covered by REPEP |
|---|
| Financial service providers and banks |
| Insurance companies and afores |
| People calling to collect a debt |
| Political organizations |
| Charities |
| Telephone pollsters |
The FAQ adds people who are not offering goods, products or services. The complaints page goes further and lists “fraudes” and “extorsiones” among the things it will not process under REPEP. So a fake bank call, a threat or a call from a collector is outside this tool, even if your number is registered.
What if you registered and the ads keep coming?
If the waiting period has passed and a business still sends you advertising, you can file a complaint. The complaints page says you can:
- Call Telcon at 5568 8722 (Mexico City and metro area) or 800 468 8722 (rest of the country), Monday to Friday, 9:00 to 18:00
- Write to repep@profeco.gob.mx
Be ready with your registered 10-digit number, the date you registered, the name of the business, the number it called from, the date and time, and what it offered. PROFECO also asks for evidence, such as a call recording or a screenshot. A complaint is rejected if you gave that business permission to advertise to you, or if the call was not advertising at all.
What should you do about the calls REPEP does not cover?
- For calls that pretend to be your bank, see our guide on fake bank calls in Mexico.
- If you answered a call and fear it was a scam, follow the checklist.
REPEP is worth five minutes because it cuts one kind of nuisance. Just do not expect it to quiet the calls that cause the real harm.
