Mexico's Federal Law on Protection of Personal Data Held by Private Parties (LFPDPPP) compliance in Mexico

Mexico's Federal Law on Protection of Personal Data Held by Private Parties (LFPDPPP) compliance in Mexico at a glance

A decree published in the Diario Oficial on 20 March 2025 gave Mexico a new Federal Law on the Protection of Personal Data Held by Private Parties, repealed the 2010 law and moved supervision to the Secretaría Anticorrupción y Buen Gobierno. For companies the practical changes are around the same core duties: lawful and proportionate processing, a privacy notice with listed contents, consent that is express and in writing for sensitive data, administrative, technical and physical safeguards, prompt notice to people affected by significant breaches, and access, rectification, cancellation and objection rights handled by a designated person or department. The law also regulates transfers and invites binding self-regulation schemes such as trust seals. It creates no certificate, and it names no ISO standard. Sterling's New York office helps organisations map data, rewrite notices, set up request handling and align security evidence, with Effivity and Sterling Academy included. Confirm legal points with your counsel or the authority.
