Entity Search
How Entity Search checks a business entity search
Quick answer. A business entity search opens the state file for a corporation, LLC, or similar entity. A company name search on the web is not that file. An EIN search by company name is not public at the IRS. A DBA is often a different record from the legal entity.
Search the entity that was formed, not the brand
Start with the legal entity, the one that can be sued and that signed the formation document. Marketing sites and “search marketing company” pages will not be in a corporations index under the slogan on an ad. Company search in the sense that matters here is the state detail page: type, status, agent, file number.
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.
