Visit the official authority ↗Understand the record
A company’s incorporation jurisdiction can differ from its principal business address. Registration to do business in another state does not necessarily create a new company.
OpenBase USA is independent of Secretary of State. Our CIK and EIN fields do not substitute for a Illinois registration number.

Verifying a Illinois company
- Search the legal name with Secretary of State.
- Match the registration number and jurisdiction, not only the name.
- Check whether the entry is a domestic entity or an out-of-state registration.
- Check the source’s current status and date. Obtain a certified document if your transaction requires one.
Record availability differs by entity type. An absent EIN, CIK or financial statement is not evidence of wrongdoing.
