Data Broker Directory

Data brokers are companies that collect, buy, and sell personal information about people they have no direct relationship with — location trails, purchase histories, family details, even sensitive categories like precise geolocation or reproductive health data. Most people have never heard of the companies holding the largest files on them. Our Learn guides explain how this ecosystem works and what you can do about it.

This directory is assembled from state registry public records: the California CPPA Data Broker Registry and the Vermont Secretary of State data-broker registry, where brokers are legally required to register and disclose their practices. "Sensitive data collected" reflects each broker's own California registration; "Opt out" links to the broker's stated privacy-rights page when it provided one.
