Overview
- The rule published in the Diario Oficial de la Federación says a CURP that contains biometric data and whose biometric validation succeeds will be sufficient to identify a worker in an Infonavit credit file.
- The modification was published August 5 and takes effect Thursday, August 6, 2026, and applications started before that date will continue under the prior rules.
- Other required documents for an Infonavit loan—proof of address, authorization to consult credit bureaus, financial-education records and modality-specific papers—remain mandatory and unchanged.
- Citizens must register biometric data with supporting documents such as a certified birth certificate, a current official ID, their traditional CURP, and a recent proof of address before they can use the biometric-CURP option.
- Infonavit is explicitly allowed to use biometric technologies that process personal data, so practical benefits depend on rollout of validation systems and will raise operational and privacy oversight questions to watch for.
