Data sources
Core public-record feeds, joined and cited.
Every ownership and regulatory claim traces back to a government filing. Filed channels are public-record facts, shown with their source and date. When you run a report, we add web-found contacts labeled by source. Here’s what we ingest, who publishes it, and how often it refreshes. No scraped broker panels, no resold contact lists.

What we leave out
No panels, no resold lists.
We don’t buy contact panels, scrape broker databases, or resell anyone else’s lists. We also hold no consumer credit data of any kind. If you’re named in a public record and want it removed from DeedGraph, the removal request form goes straight to a human.
