Mexico advances mandatory mobile‑line registration with CURP link

The Mexican government is moving forward with a law that requires every mobile phone line to be linked to the user’s CURP (Clave Única de Registro de Población). The deadline for completing the registration is 29 June 2026; after that, telecom operators must suspend any unregistered lines, although they will still be able to call emergency services. Exceptions apply to SIM cards used only for tracking devices, sensors and other equipment that do not support voice calls or SMS.

President Claudia Sheinbaum announced that more than half of the country’s roughly 144.5 million active lines have already been registered. A detailed balance will be presented later this week, and the administration has not ruled out a possible extension for users who have not yet complied. Registration can be done online or at carrier service centers, requiring a valid ID and the CURP. The measure is promoted as a tool to combat fraud, extortion and other crimes committed through anonymous phones, while telecom companies, not the government, retain the data and may be queried only in formal investigations. Critics warn of privacy risks and cite previous court rulings that struck down similar registries.
