🛡️ A New Legal Framework That Changes the Rules of the Game of Data Protection in Mexico

On March 20, 2025, the Federal Law on the Protection of Personal Data Held by Private Parties (LFPDPPP) was published in Mexico’s Official Gazette of the Federation.This new law replaces the 2010 version and introduces a far more rigorous framework governing how companies collect, process, store, and transfer personal data.

Its main goal is clear: to guarantee individuals’ privacy and their right to informational self-determination, ensuring that personal data is handled lawfully, transparently, and responsibly.

One of the most significant institutional changes is the creation of the Secretariat of Anti-Corruption and Good Governance, which now replaces the former INAI (National Institute for Transparency and Access to Information) as the supervisory authority for data protection compliance in Mexico.

⚙️ The Essentials Every Company Must Understand (and Apply Starting Now)

At UPLAW Abogados | Attorneys-at-Law, we’ve analyzed the key aspects that every business must immediately adopt to comply with the new law and avoid sanctions.

1. Core Principles of Data Processing

Article 5 of the new law establishes that every organization processing personal data must observe the principles of lawfulness, purpose, loyalty, consent, quality, proportionality, information, and accountability.In practical terms, this means:

• Data must be collected for legitimate, specific, and informed purposes.

• Information must be accurate and up to date.

• Data may be kept only for as long as necessary to fulfill its purpose.

• The organization must ensure adequate security measures at all times.

2. Clear and Revocable Consent

Under Articles 7 and 8, no personal data may be processed without the data subject’s consent, except in specific circumstances such as legal obligations or medical emergencies.Consent may be express or implied, but for financial or sensitive data, it must be express and in writing.Furthermore, consent can be revoked at any time, and companies must provide a simple and free mechanism for data subjects to exercise this right.

3. Transparent and Complete Privacy Notice

Article 15 sets forth the mandatory elements of a privacy notice, which must include:

• The identity and address of the data controller.

• The categories of personal data being collected (including sensitive data).

• The purposes for processing.

• The available options to limit data use or disclosure.

• The procedures for exercising ARCO rights (Access, Rectification, Cancellation, and Objection).

• The method to communicate any changes to the notice.

This privacy notice must be made available at the time of data collection (Article 16), whether in print, electronic, or any other form.

4. Strengthened ARCO Rights

Articles 21 through 34 reaffirm the rights of Access, Rectification, Cancellation, and Objection, which must now be handled within shorter deadlines and with full transparency.Companies are required to:

• Designate a Data Protection Officer or department (Article 29).

• Respond to requests within 20 business days.

• Keep documentary evidence of every ARCO request handled.

Failure to respect these rights constitutes a serious violation and may lead to significant fines.

5. Mandatory Security Measures

According to Article 18, companies must implement administrative, technical, and physical safeguards to protect personal data against damage, loss, alteration, destruction, or unauthorized access.These measures must be proportional to:

• The sensitivity of the data.

• The potential risks involved.

• The nature of the company’s operations.

Additionally, any security breach that significantly affects individuals’ rights must be immediately reported to the affected parties (Article 19).

6. Transfer and Third-Party Data Control

Under Article 35, when a company transfers personal data to third parties, it must inform them of the applicable privacy notice and ensure they assume the same obligations as the data controller.Article 36 allows certain transfers without consent, such as:

• Those required by law.

• Transfers within the same corporate group under common privacy policies.

• Transfers necessary for justice administration or legal defense.

7. Severe Sanctions and Criminal Penalties

Articles 58 through 64 establish fines ranging from 100 to 320,000 times the UMA (Mexican daily unit of measure), which can double for sensitive data violations.Moreover, the unlawful or deceptive use of personal data for profit may result in imprisonment of up to 5 years.The message from lawmakers is clear: data protection is no longer optional.

💡 Beyond Compliance: Turning Privacy into a Competitive Advantage

Complying with the law is not just about avoiding penalties — it’s about building trust.Companies that manage personal data correctly enhance customer confidence, strengthen loyalty, and reduce operational losses linked to data breaches.A solid privacy culture also improves your corporate reputation and facilitates partnerships with international clients and investors.
