Record and FAQ counts are approximate. Company search coverage follows the current list. The company estimate refers to cumulative U.S. registration records in OpenCorporates, including historical and interstate registrations; actual search and verification availability depends on the returned results.

Company registrations

Company searches and name checks use state public registration records; nationwide searches combine the name-search results returned across states. Available regions follow the current list. Fields, history and dates vary, and not every state may return information for a given search.

Search companies

Federal trademarks

Trademark searches cover public USPTO federal applications and registrations. A name search is not a complete clearance or infringement review.

EIN verification

Check whether a business name and EIN match. Matching follows the upstream tax-name rules and does not verify every character of the full legal name. A match does not establish standing, creditworthiness or authority. Recently applied-for numbers may not yet appear in available records.
