Does Realcaller work in Mexico?
The app does: it runs fully in Spanish and can look up any number. The spam data does not yet. There is no Mexican data in it today, and Mexican coverage can only come from reports by Realcaller users.

What works in Mexico today?
Everything about the app itself. What is missing is Mexican spam data, covered in the next section.
The whole app in Spanish
Screens, cards, reasons and buttons, written for Mexico with “tú”. Pick it in the phone’s settings or let it follow the phone.
Search any number
Type or paste a number and see the verdict, the risk score and the reasons. A number with no data says it is new and has no reports yet.
The top US numbers, offline
A Mexican phone still downloads the most-reported US numbers into its offline list, so those are caught even without a connection.
Reports from Mexican users
Anyone can report a number in two deliberate steps. Reports are how Mexican numbers will get flagged. There were none yet as of October 7, 2026.
What does not exist yet?
Mexican spam data. Realcaller has no numbers flagged from Mexico, so a Mexican scam call will most likely show as a new number with low risk.
- Mexico has no public, downloadable list of reported phone numbers that the app can use today.
- The regulator that used to take these complaints (the IFT) no longer exists, and its successor publishes no list of reported numbers.
- PROFECO’s data has no phone numbers in it.
- CONDUSEF offers a web lookup you use one number at a time, but no dataset the app can load.

Which calls does REPEP not cover?
REPEP, PROFECO’s free list for stopping advertising calls and texts, does not cover calls from banks and many other callers. PROFECO says so on its own site.
PROFECO states it is not competent over phone calls from:
- banks and other financial services
- insurers
- afores
- collection agencies
- political groups
- charities
- pollsters
The complaints page of REPEP also lists fraud and extortion as outside its scope. That is where a lot of dangerous calls fall: a “bank” asking for your data is a scam, not an advertisement.
Realcaller is meant for exactly these calls, with a limit you should know about: it can only warn about a Mexican number once reports about it exist.
Read what REPEP stops and what it does notWhat official tools can you use in Mexico?
Three official sites are worth knowing. All are free, and none replaces your own judgment on a call.
REPEP, from PROFECO
Add your number to stop advertising calls and texts from companies that follow the rules. Registering is free and takes under a minute; it applies about a month later.
Number check, from CONDUSEF
Type a number (with the international prefix) to see if it has reports linked to fraud or spam, and report one. It is a manual lookup, one number at a time.
Line registration, from the CRT
Prepaid lines must be linked to a CURP through the phone company. It aims at anonymous lines used in crimes; it is not a spam filter.

What does Mexico’s REPEP stop, and what does it not?
How to join, how long it takes, and why banks and scams are outside it.
Got a call from your “bank”? What to do
What banks never ask by phone, and the steps if you shared data.
Mobile line registration: what it is and is not
The official deadlines by last digit, and why it is not a spam filter.
You answered a scam call. What now?
Checklists for Mexico and the US depending on what you shared.
How will Mexican coverage grow?
Through reports from people in Mexico. Each report is a deliberate act, so the data stays clean.
- A report takes two steps: you pick the kind of call, then you confirm.
- A report raises the number’s score on live checks right away.
- A number reported by a second phone goes into every phone’s offline list.
- A label such as Scam appears once two phones agree within 90 days.
None of this has produced Mexican data yet. We will not say the app “covers Mexico” until it does.
