ANPD launches public consultation on the Guide to Anonymization and Pseudonymization

In a significant move towards strengthening data protection practices, the Brazilian National Data Protection Authority (“ANPD”) has opened a public consultation on its draft guidelines for anonymization and pseudonymization. The document, available for review on the official ANPD website, aims to gather input from various stakeholders to ensure comprehensive and effective guidance in handling personal data.


ANPD has taken a proactive step by inviting public participation in shaping guidelines for anonymizing and pseudonymizing personal data. The consultation period, which began on January 30 and will continue until February 28, encourages input from individuals, organizations, and experts in the field.

Anonymization and pseudonymization are crucial processes in the realm of data protection, as they involve the transformation of personal information into a form that cannot be directly attributed to an individual. These practices play a key role in mitigating  risks associated with privacy breaches while allowing the legitimate use of data for various purposes.

How to Participate

Interested parties can access ANPD’s preliminary studies on ANPD’s website. Access to the full draft guidelines as well as submission of contributions should be done exclusively via the Participa Mais Brasil platform. Any reports, images or other attachments that form part of your contribution can be sent to during the consultation period. Only material that complements the contributions will be accepted by e-mail.

Following the conclusion of the public consultation period,  ANPD will review  contributions and make any necessary adjustments to the guidelines. The finalized version will serve as a comprehensive resource for companies  navigating the challenges of data anonymization and pseudonymization while upholding privacy standards.


ANPD's collaborative approach on seeking public input on the draft guidelines reflects a commitment to transparency, collaboration, and inclusivity in shaping data protection policies. By involving a diverse range of stakeholders, ANPD aims to ensure that the guidelines meet the highest standards and effectively contribute to safeguarding personal data in Brazil.
