Mexican civil society groups are warning of major privacy and human rights risks from new legislation requiring biometric data collection for the country’s national identity system. Reforms to the General Population Law mandate that all citizens provide fingerprints, iris scans, and photographs to create a biometric version of the CURP (Clave Única de Registro de Población), stored in a centralized “Unique Identity Platform.”
Mandatory Biometric CURP and Legal Challenges
The biometric CURP is slated to become obligatory for accessing public and private services by February 2026. In practice, traditional CURP numbers without biometric data will no longer be sufficient for many official transactions. Rights advocates note that this makes biometric enrollment functionally mandatory for the population. Courts in Yucatán, Querétaro, and Mexico City, however, have issued injunctions temporarily suspending enforcement of biometric requirements, citing constitutional and data protection concerns.
The legislation gives broad access to biometric and personal information to law enforcement, intelligence agencies, and the National Guard. Critics argue that this scope, combined with plans to link the database to financial, health, and telecommunications records, risks exposing sensitive data to misuse or unauthorized surveillance.
Opposition from Civil Society and Global Parallels
Digital rights organizations, including R3D (Red en Defensa de los Derechos Digitales), Article 19, and Access Now, argue that centralizing biometric identifiers poses unacceptable risks of discrimination, wrongful arrests, and abuse. The Electronic Frontier Foundation (EFF) has joined calls for international attention, warning that Mexico’s reforms reflect a broader global trend of governments deploying biometric surveillance without adequate oversight or safeguards.
These reforms follow earlier attempts to create the PANAUT biometric SIM card registry, which Mexico’s Supreme Court declared unconstitutional in 2022. More recently, a federal tribunal in Yucatán suspended implementation of the biometric CURP rollout, underscoring the legal uncertainty around the measures. Rights groups caution that once such systems are entrenched, preventing misuse by authorities becomes extremely difficult.
Observers note that Mexico’s move parallels international developments, including expanded biometric collection at U.S. border crossings. Advocates say the convergence of mandatory digital identity systems and wide-ranging state access raises urgent questions about privacy, transparency, and proportionality in security policies.
