To comply with Mexico’s LFPDPPP, obtain user consent, respect purpose limitation and data minimization principles, implement mechanisms for ARCO requests, create a Privacy Policy, implement security measures, sign contracts with service providers, and implement a Consent Management Platform like CookieScript to create a Privacy Policy and obtain user consent.
Ley Federal de Protección de Datos Personales en Posesión De los Particulares (LFPDPPP), the Federal Law on the Protection of personal data Held by Private Parties, became effective in 2010. Mexico Data privacy law applies to all private‑sector organizations that collect or use personal data in Mexico.
In March 2025, the Mexican government adopted a new data protection law, bringing Mexico's privacy standards closer to international standards while preserving its unique characteristics. These updates address data processing challenges, including artificial intelligence, and introduce important changes to consent requirements. The 2025 updates also set stricter controller responsibilities and enforcement.
These recent amendments reflect Mexico’s growing commitment to data privacy, aligning its data protection laws more closely with international standards like the EU’s GDPR.
This guide breaks down the key elements of Algeria’s privacy law, user rights, business obligations, and compliance steps under Mexico’s Data privacy law.
What is Mexico Data Privacy Law (LFPDPPP 2025)?
LFPDPPP is the Federal Law on the Protection of personal data Held by Private Parties in Mexico, that regulates how private entities collect and process personal data in Mexico. It aims to protect personal data held by private entities and safeguard individual privacy rights, as established in Article 16 of the Mexican Constitution.
Effective date: March 21, 2025.
Official law text: Mexico LFPDPPP.
The law is enforced by the Secretariat of Anti-Corruption and Good Governance, replacing the National Institute of Transparency, Access to Information, and Protection of Personal Data (INAI). This change represents a shift from independent regulatory oversight to centralized enforcement.
The law empowers individuals to control how their Personal Information is used, providing them with ARCO rights: Access, Rectification, Cancellation, and Opposition.
The Mexico Data privacy law expanded its scope and now clearly includes data processors, making sure all parties have direct legal responsibilities.
The law also updated definitions of "consent," "personal data," and "privacy notice", that provide clearer guidance regarding the use of new technologies, including artificial intelligence and automated decision-making.
Who Does Mexican Privacy Law Apply to?
Mexico Data Privacy Law LFPDPPP applies to all individuals or private entities that process personal data for professional or commercial purposes in Mexico.
The law also applies extraterritorially in the following cases:
- Controller established in Mexico
When processing is carried out by a processor, regardless of its location, on behalf of a controller located in Mexico. - International law or contracts
When the controller is not established in Mexico but is subject to the LFPDPPP because of international law or through the execution of a contract. - Use of means in Mexico
When a controller is not established in Mexico but uses means located in Mexico to process data. Means, used solely for data transit, are except from the regulation.
The data controller now includes any person or entity that processes personal data, even if they do not decide why or how to process the data. Therefore, service providers and processors also become responsible for complying with the law.
ARCO Rights: Mexico's Data Subject Rights Framework
ARCO rights are comprehensive data subject rights in Mexico that include the rights to Access, Rectification, Cancellation, and Opposition. These rights have been strengthened under the 2025 framework.
- Right to access
The data subject has the right to access their personal data that the controller possesses. Controllers must provide responses within 20 business days in accessible formats. The privacy notice must inform how the controller uses the Personal Information. Organizations must keep all personal data, identifying individuals, classified across databases and applications, and associated with the requesting individuals. Complete responses to data access include data categories, processing purposes, retention periods, and automated decision-making information. - Right to rectification
Individuals can request the rectification or correction of incomplete or inaccurate personal data. Rectification rights extend to automated decision-making processes producing significant effects on data subjects. - Right to cancellation
Data subjects can request cancellation of their personal data when processing purposes end or consent is withdrawn. The controller must eliminate the data from the files, records, and systems permanently, so that they no longer could be accessed by the controller. - Right to oppose
The data subject may oppose or demand to stop data processing in cases of:
A legitimate cause, when continued processing would cause harm, even if lawful.
Their data is subject to automated processing that produces legal effects or significantly impacts their rights or freedoms
Data controllers must implement opt-out mechanisms that allow individuals to exercise their rights while not discriminating against individuals and enabling service for them where possible.
Core Principles of Data Protection Under the Mexico Data Privacy Law
Here are the main obligations established by the LFPDPPP:
- Transparency
Controllers must provide a privacy notice to inform individuals about the collection and processing of their data prior to the data collection. - Consent
To process personal data, controllers must obtain consent of the data subject. There are some exceptions: the use of Anonymized data or public data does not require obtaining consent. - Lawfulness
Controllers must collect and process personal data lawfully, without any deceptive or fraudulent means. - Purpose limitation
Controllers must collect data only for specific, explicit, and legitimate purposes. Don’t use personal data for purposes other than specified at the time of collection. Processing of sensitive data should be limited to the minimum period necessary. - Data minimization
Controllers must collect only the minimum amount of data needed to deliver the product or service. - Data safety
Controllers must protect data from loss, leaks, or misuse using adequate technical and organizational means. - Data quality and accuracy
Controllers must ensure that personal data is maintained accurately, completely, and up to date. Businesses must respect employees’ and clients’ rights to access, correct, or delete inaccurate information. - Accountability
Controllers are directly responsible for ensuring compliance with the principles. They must implement necessary measures to enforce the law and ensure that third parties on behalf of them also comply with the obligations of the law. - Data breach notification
If a security incident affects users’ personal data, controllers are legally required to notify the affected individuals.
What Are the Consent Requirements Under Mexico Data Privacy Law?
Under Mexico Data Privacy Law, consent must be free, specific and informed. Implied consent is valid if individuals are informed and do not object for their data management. Explicit consent is mandatory for sensitive personal data, financial data, and international transfers.
- Free: Individuals should provide consent freely, without any pressure or coercion. Don’t use cookie notice that encourages giving consent.
- Specific: Controllers can’t include any condition requiring consent to purposes beyond those agreed upon.
- Informed: Consent must be obtained when individuals are fully informed about the use of their personal data. Consent is not valid if obtained without proper information. Do not use dark patterns or other misleading behavior to obtain consent. If the individual does not interact with the Cookie Banner, continues scrolling, or does not take any action, it does not mean that they give consent to collect their data.
When authorized by regulations, processing without consent is allowed. Such situations include legal requirements, publicly available data, and vital interests.
Data subjects may withdraw consent at any time. Controllers must respect the withdrawal of consent and keep records of consent and withdrawals.
Transparency Requirements: What Privacy Policies Should Include?
Mexico data privacy law prioritizes transparency in a way that aligns closely with international standards like the EU’s GDPR.
The Privacy Policy must be easily accessible to data subjects. Businesses should provide at least the following information on their Privacy Policy:
- Identity of the controller.
- What personal data is collected?
- Purposes of data collection and processing.
- Sensitive data involved in processing, if any.
- Third parties, to whom the data will be shared, if any.
- Personal data retention period.
- Methods for individuals to exercise their ARCO rights.
- Methods by which the business will communicate any updates to the privacy policy.
- Whether data will be transferred abroad, and if so, where, and what safeguards will be applied.
- Methods to withdraw consent.
Before collecting any personal data, controllers must provide a privacy notice that asks for user consent to collect personal data and includes an active link to the Privacy Policy.
The privacy notice must be simple, written in a clear and understandable language, and contain the necessary information.
The easiest way to provide a privacy notice and obtain user consent is through the Cookie Banner.

AI and Automated Decision-Making Governance Under the Mexico’s LFPDPPP
Mexico Data Privacy Law introduces progressive provisions regarding the use of artificial intelligence (AI) governance and automated decision-making tools significantly affecting individual rights. With these provisions, Mexico now stands as as a regional leader in AI governance.
Controllers using AI and automated decision-making systems to handle user data must provide clear notice to individuals, including information about algorithmic logic, the significance of automated processing, and potential consequences. Controllers must obtain informed consent for processing personal data using AI and automated decision-making systems.
High-risk automated decision-making systems require impact assessments evaluating potential effects on individual rights while identifying appropriate safeguards and mitigation measures.
Individuals have the right to object to the processing of their data with automated decision-making systems.
Rules for International Data Transfer
Transfers of personal data outside Algeria are strictly regulated. Cross-border data transfer compliance requires adequate protection for Mexican personal data processed in foreign jurisdictions. Personal data may only be transferred abroad if the receiving country ensures an adequate level of protection.
Controllers must demonstrate that the receiving country ensures adequate data protection or obtain special authorization where required.
Controllers must provide clear information about destination countries, recipient organizations, and protection standards, and obtain informed consent from individuals for information transfers.
Enforcement of Mexico Data Privacy Law LFPDPPP and Penalties for Non-Compliance
The law is enforced by the Secretariat of Anti-Corruption and Good Governance, replacing the National Institute of Transparency, Access to Information, and Protection of Personal Data (INAI). This shift affects investigation procedures and penalty assessment while maintaining data safeguard standards.
Failure to comply with the LFPDPPP can result in significant fines and reputational damage.
Administrative fines range from 100 to 320,000 times the minimum daily wage, depending on the severity of the violation. Higher penalties are set for sensitive data breaches and repeat offenders.
Criminal sanctions apply for severe violations involving sensitive data or deceitful processing.
