Registry reference

Every registered broker, and what it admits to holding.

California requires data brokers to register and to declare which categories of sensitive personal information they hold. 581 registrations, reproduced with the privacy-rights URL each one is obliged to publish.

Organised by domain, which gives 558 pages: several companies register more than once under one domain. Both numbers are on this page because they measure different things and only one of them is the size of the register.

This is public record. We did not discover it and we do not own it — we keep it readable and generated from the same file our engine reads, so it does not go stale.

Two-thirds of the register declares none of the nine categories.

California asks every registrant which categories of sensitive personal information it holds. This is how they answered. Declaring none may be perfectly true of a broker that deals only in business contact data — the register records the answer, and so do we.

384 declare none 66.1%
197 declare at least one 33.9%
Of the 197 that declare anything: 142 declare one category, 32 two, 14 three, 9 four or more. 38 distinct declaration patterns across 581 registrations.

Snapshot taken 2026-07-24. That is when we copied the register, not when the register last changed — the published file carries no publication date of its own, so we cannot tell you its currency and do not imply it. Check cppa.ca.gov for the live version.
