CNBV adds facial biometrics to Mexican banks

New requirement for Mexican banking

Mexico’s National Banking and Securities Commission, known as the CNBV, has amended the Banks’ Single Circular to add facial biometrics to customer identification, according to LYPmultimedios. The decision covers account openings, loans and high-value transactions in Mexico.

What PLD.mx says about implementation

PLD.mx reported that the combined requirement for official identification and biometric data for cash deposits and withdrawals of 140,000 pesos or more at the teller window is already operating in Mexican banking, and described it as a measure in force since July 1, 2026. The same coverage said the full technical integration of all banks to comply with the new biometric requirement should be completed by July 30, 2026.

That deadline, according to the regulatory summary from the specialized outlet, suggests a shorter operational window than the 90 business days mentioned in other coverage. The available material does not spell out the scope of those other reports, but it does show that the banking sector is facing an accelerated technical adjustment to meet the new requirement.

Operational scope

Based on the information provided by the sources, the move combines two fronts. On one side, the CNBV added facial biometrics to customer identification mechanisms under the Banks’ Single Circular. On the other, the ABM is linked to the requirement for official ID plus biometrics for high-value cash transactions at the teller window, specifically starting at 140,000 pesos.

The research material does not include an additional official statement or technical explanation of the internal changes institutions will have to make, but it does place the measure already in application, with an integration window that would close at the end of July 2026.
