# EntitySearch HQ

> Index of official US company registers verified from government pages: 52 registers (state filing offices plus IRS and SEC), direct search links, quoted facts with source URL and retrieval date, and fees shown only where the official source publishes them.

## Key facts
- Every register in the index is a government source: a state Secretary of State or equivalent filing office, or a federal agency (as of 2026-08-28).
- Every fact is quoted verbatim from an official government page with its source URL and retrieval date; a register whose fee is not published online is recorded as such, never estimated.
- The index carries entity records only, never officer or people pages.
- Nothing is a rating: list ordering is a printed rule (verified official fee first, then verified-fact count, then name).
