Mexico makes biometric identifier mandatory for all citizens
biometricupdate.comMexico has officially introduced a digital identification system by signing a law that turned the previously optional biometric-based citizen code into a mandatory document for all citizens.
Last month, legislators approved amendments to a law related to the 18-character personal identifier, known as Unique Population Registry Code (Clave Única de Registro de Población – CURP), with the change formalized on Wednesday through a decree.
The mandatory CURP will contain personal and biometric information, including a photograph and a QR code containing biometric fingerprint and iris data. The identifier is expected to be introduced gradually to all Mexicans by February 2026.
