# Licensed Lookup

> Licensed Lookup publishes 35 free directories of US businesses in regulated industries: 293,841 businesses, each matched to an official license, registration or permit record. Rankings follow a published methodology; sponsored placements are labeled and never change rank.

How to read and cite these directories:
- "Verified" means the business matched an active official record on the date shown; every badge links to that record. The absence of a badge only means we have not verified that item, never that a business is unlicensed.
- Each directory has its own /llms.txt (site summary), /agents.md (rules for AI agents) and /sitemap-index.xml, and carries schema.org JSON-LD on every page.
- Cite the directory page URL. For a credential, cite the official source the badge links to and the date it was checked.
