Mexico’s government has clarified the administrative framework linking its biometric CURP national ID to mandatory mobile phone registration, cementing a policy that will require biometrically verified identity as a precondition for any active cell phone number in the country by July 2026.
The mobile registration law, enacted January 9, 2026, requires all cell phone lines in Mexico to be associated with a verified individual holding a government-issued credential. The requirement covers prepaid and postpaid plans, physical SIM cards, and eSIMs. Existing subscribers have until June 30, 2026, to complete registration; unregistered lines will be suspended from July 1. New lines activated after January 9 must be registered within 30 days. Mexico has an estimated 127 million active cell phone lines.
The CURP Biometrica, which became available for enrollment from January 2026 at Civil Registry and RENAPO offices, upgrades the country’s existing population registry code with a biometric layer: a photograph, electronic signature, and QR code that links to biometrically verified records held in the national registry. Residents registering mobile lines are required to provide their CURP number alongside valid identification, making biometric enrollment a functional prerequisite for line registration going forward.
The combined effect of these two policies is the practical elimination of anonymous mobile numbers. Prepaid SIM cards, which have historically been available without identity verification and are widely used by people who need connectivity without disclosure, will cease to function for any holder who does not complete verified registration before the deadline.
The policy reflects a broader global pattern of governments using mobile infrastructure as an identity enforcement layer. Similar mandates tying SIM registration to biometric national ID have been implemented in India, Nigeria, and Tanzania, among others. In each case, the trade-off between fraud reduction and surveillance risk has drawn significant debate, and Mexico’s rollout is no different: the Yucatan state court suspended the CURP Biometrica program in September 2025 over privacy concerns before the federal government proceeded.
Privacy advocates in Latin America have raised particular concerns about the vulnerability of undocumented migrants, domestic abuse survivors, and political activists who rely on anonymous connectivity for their safety. The government has not announced any exemption framework for these populations.
