CURP Reforma Biométrica LGP ​​DOF 2025-07-16 — Implicação na Diáspora (Pendente de Implementação Operacional)

The CURP Biométrica reform (Decreto DOF 2025-07-16, Reform 20 to the Ley General de Población) transforms the Clave Única de Registro de Población from a pure alphanumeric identifier into a biometric national identity document incorporating fingerprints (huellas dactilares) and a photograph. This reform, effective DOF 2025-07-17, is significant for the MX nationality knowledge base because the CURP is the foundational identity document linked to Mexican nationality certification, naturalization records, and diaspora registration — and its transformation into a biometric credential affects every downstream nationality act that relies on CURP as proof of Mexican identity.

The Decreto modifies Art 91 of the Ley General de Población (LGP) to establish that the biometric CURP constitutes a documento nacional de identificación obligatorio with universal acceptance across all federal, state, and municipal governmental acts. It adds Art 91 Quater, which establishes the Plataforma Única de Identidad (PUI) as the RENAPO-operated platform integrating biometric enrollment, CURP validation, and identity verification. RENAPO — the Registro Nacional de Población — is the authority responsible for operational rollout.

The reform establishes two enrollment timelines:

• General enrollment (adults): 90 días (calendar) from EIF for existing CURP holders to enroll biometric data at RENAPO service points or designated enrollment centers
• Minor enrollment (Programa Integración Biométrica menores): 120 días (calendar) from EIF for enrollment of minors into the biometric system, coordinated through schools and health centers (Secretaría de Educación Pública and IMSS/ISSSTE coordination)

The diaspora implication is the primary relevance to this knowledge base. As of 2026-05-17, operational rollout is "pending" for Mexican nationals abroad — the 53-consulate network (documented in MX-XCT-CONSULAR-01) has not yet been equipped with biometric enrollment infrastructure. RENAPO has announced plans to coordinate consular biometric enrollment, but no Acuerdo or implementing decree has been published establishing the consular rollout timeline. This creates a procedural gap: Mexican nationals abroad who require a CURP for naturalization acts (e.g., filing a naturalization application in Mexico, recovering nationality under the indefinite Art Cuarto Transitorio window, or declaring for renunciation) will encounter a biometric enrollment requirement that the consular network cannot yet fulfill.

The interaction with the apostilla elimination (CNDOC Arts 314 + 1144 DOF junio 2024) also creates a documentary coordination question: the CNDOC apostilla elimination simplified cross-border document authentication, but the biometric CURP requirement adds a new biometric data layer that was not anticipated in the CNDOC reform. Whether the SINNA portal (sinna.sre.gob.mx) will be updated to require biometric CURP validation for digital nationality certificates is a pending question as of 2026-05-17.
