Businesses must register with the Secretary of State office in the state they are located. Search Systems provides a meta search for all states in the U.S. and provinces in Canada. The best way to proceed is to choose “Corporations and Companies” and then select the state or province where the firm is headquartered. This will bring you to one or more corporate directories. This may vary by state or province. You can also search by state or province alone and explore all the possible information that is collected.
Open Corporates also provides access to public records on privately held firms worldwide.
USAspending.gov can help you identify subsidiaries by searching for a company, clicking on an award, and clicking “view child recipients.”

Some fold new acquisitions into the parent company, while others maintain them as subsidiaries. These differences may or may not be of any significance.
