What is an aviso de privacidad?

It is the mandatory privacy notice required under Mexican law. It must clearly tell data subjects what data is collected, the purposes, and how to exercise their rights, and it is a central compliance obligation.

Does Mexico require opt-in consent?

For ordinary data, consent can be tacit, meaning silence after a privacy notice can suffice. Express consent is required for financial data, and written consent for sensitive data.

Consent and privacy law in México

Mexico's private sector law is the Federal Law on the Protection of Personal Data Held by Private Parties, dating from 2010 and historically overseen by INAI. A distinctive feature is the privacy notice, the aviso de privacidad, which is a mandatory and detailed disclosure that must be provided to data subjects. Consent can be tacit for ordinary data, meaning silence after a notice can suffice, but express consent is required for financial and sensitive data, and written consent for sensitive data. This tacit consent model is softer than the EU approach. Note that Mexico has been restructuring its transparency bodies, so the supervising authority arrangements have been in transition.
