This thread has come full circle.
There are many things that might be used to identify a business from a partnership agreement, articles of organization, articles of incorporation, certificate of good standing, Secretary of State registration, state comptroller's registration, etc. The variety among states is nearly infinite.
If the specific document you use carries a number assigned by the state that could be used to research or verify the document, then put it on the form. If not, leave it blank.
P.S. The report already elicits the EIN.
