Mexico Moves Toward Nationwide Biometric CURP

Mexico is preparing to scale up a biometric version of its Unique Population Registry Code (CURP), adding biometric identifiers to a credential that already underpins most administrative processes in the country. The updated CURP keeps the familiar 18-character code but incorporates fingerprints, a facial photograph, an iris scan and an electronic signature to support stronger identity verification.

According to Mexican media reports, in-person enrolment began in January 2026 at Civil Registry modules and offices of the National Population Registry (RENAPO), described as a transition period ahead of a phased move toward mandatory use from 1 February 2026. Pilot tests started in July 2025 in several locations, including Veracruz and Mexico City, before the planned broader rollout ¹. Early implementation will likely hinge on how quickly appointment capacity and staff training can scale across states, particularly outside major urban centres.
