Publicly Traded Data Brokers
Every SEC-reporting company whose core business involves consumer-data brokerage, credit reporting, adtech, identity resolution, or data analytics, indexed with CIK, SIC code, and the direct URL to their most recent 10-K. Each entry also surfaces the consumer opt-out route under state privacy law. Source data: SEC EDGAR (data.sec.gov). Index last refreshed 2026-04-24.
Why public matters: SEC filers must disclose material data-practice risks, breaches, and regulatory exposure under Regulation S-K Item 106 and general disclosure rules, sworn to by executives under Sarbanes-Oxley § 302. These disclosures are the most authoritative free source for understanding what a broker actually does with consumer data. Private companies have no equivalent obligation.

Public status doesn't change your opt-out rights, state privacy law applies the same way. OfflistMe generates the CCPA-compliant deletion email for each broker; you review and send from your own inbox.

- Primary source: SEC EDGAR submissions API (
data.sec.gov/submissions/). This is the canonical public record for every company with registered securities. - Curation: Companies are included if their principal business, or a material reported segment, involves aggregating, selling, scoring, or monetizing consumer personal data. Evidence is the company's own SIC code, 10-K business description, or publicly stated registration as a data broker under a state statute.
- Refresh cadence: The ingest script respects SEC's 10-request/second ceiling with a 1-req/sec limit and caches responses to avoid unnecessary load. Rebuilt on a manual cadence when new 10-K filings are relevant.
- License: SEC filings are US federal government works in the public domain (17 USC § 105). The OfflistMe presentation layer is OfflistMe’s; every page links back to the primary filing on sec.gov.
