Entity Search
What changed on Entity Search
2026-10-13 business entity search pass
Entity Search published the business entity search guides on entitysearch.io. Jurisdiction pages name the office on file and say what that search does not prove.
An EIN is a federal tax identifier. The IRS does not offer a public EIN search by company name. An EIN appears in a state filing only when someone typed it onto a form the state posts. If it is not there, no honest entity search can supply it. Do not send a request asking us to “look up the EIN” as if it were on the charter by default.
Entity Search is not a government index and cannot reveal an EIN that was never filed in public.
