Overview

• RENAPO has installed 145 physical modules nationwide and activated the Llave MX digital platform to prepare for voluntary biometric CURP registration beginning October 16, 2025.
• Citizens may register fingerprints, iris scans and digital photographs free of charge at modules or online without affecting the INE voter credential’s role.
• All public and private entities must accept the updated CURP when presented, facing fines of 10,000–20,000 UMAs for failure to integrate or receive it.
• SEGOB is finalizing secondary regulations to oversee system integration, with agencies given until mid-October to complete upgrades under the 90-day deadline.
• The biometric CURP becomes mandatory for all official transactions in February 2026, aiming to bolster identity security, streamline services and support missing-persons investigations.
