Mexico is entering a new phase in official identification with the implementation of the biometric CURP, an upgraded version of the Unique Population Registry Code that incorporates biometric data to strengthen security and prevent identity theft.

Starting in February 2026, the CURP will be required to include biometric information, linking the traditional 18-character alphanumeric code to unique personal identifiers such as fingerprints, iris scans, facial recognition, and an electronic signature. The goal is to create a secure, unique, and reliable digital identity system.

What information will the biometric CURP include?

In addition to the traditional alphanumeric code, the new biometric CURP will store:

• Fingerprints from both hands
• Iris scans
• Full-face photograph
• Electronic signature

The document will also contain the following information:

• First and last name(s)
• Date of birth (year, month, and day)
• Sex or gender
• Place of birth
• Nationality
• Fingerprints
• Photograph

Enhanced security and broader use

The biometric CURP aims to eliminate duplicate records and strengthen security in both public and private procedures through integration with the National Population Registry (RENAPO) platform.

The document will be used for a wide range of services and procedures, including healthcare services (IMSS), education (SEP), immigration procedures, and banking operations.

Mandatory in-person process starting in 2026

The process will be free of charge and must be completed in person by appointment at Civil Registry or RENAPO offices. Applicants will need to present official identification documents and a birth certificate in order to update their records.

Beginning in 2026, the biometric CURP will become mandatory for official identification purposes.
