Overview
- The mandatory program requires each mobile number to be linked to a person's CURP and carriers will begin suspending lines that remain unregistered after the June 30, 2026 deadline.
- Authorities say the registration does not create a government‑run central database and that individual telecom companies will hold users' CURP and ID records.
- Federal tribunals have issued individual suspensions preventing providers from demanding biometric data for some plaintiffs, a development highlighted publicly by magistrate Isidro Muñoz.
- Compliance is far from complete with regulators reporting about 60 million lines linked out of roughly 144 million active accesses, leaving tens of millions at risk of suspension.
- Reported security flaws in operator registration portals and warnings from the Association of Banks of Mexico that suspended lines could block SMS or call-based authentication have increased public distrust and spurred a small black market for pre-registered SIMs.
