What we know about this broker
KnowWho is a 50-year-old government-relations data company holding contact and profile information for federal, state, and local elected officials and their staff (congress, federal executive, state legislators, local government). Registered as a data broker in California (OAG #195971) and Vermont. The privacy page at knowwho.com/service/privacy/ had an expired TLS certificate as of 2026-06-16; the CA OAG registration confirms opt-out is accepted via email, webform, written letter, or phone. Privacy contact is [email protected]. No public profile to rescan — broker-confirmed only. Category set to b2b_contact because the data concerns public officials, not consumer people-search records. Classified tier 3 (manual/opaque) due to no automated web form confirmed live. Legal basis asserted under CCPA-1798.105 (deletion right). Confirm TLS cert is renewed before automating the web form channel.
