Search the Illinois business register
How to look, and what a clear result does not mean.
Search by Keyword first when testing a name you want.
Try Partial Word if you are unsure how a name is spelled.
Use the File Number when you want one specific company.
Drop the LLC or Inc suffix and the punctuation before concluding anything.
Remember a clear result is not a reservation and not an approval.
Check the county clerk instead for a sole proprietor or general partnership.
