I apologize for all the IPC-600 / 6012 questions in Technet....I just today discovered the separate 600 / 6012 forum, and have requested to join it, but I am not yet active... Anyway, I was attempting to send in a Standard Improvement Form from IPC-A-600G, and the address on the form is: IPC 2215 Sanders Road Northbrook, IL 60062-6135 It came back to me as "Not Deliverable As Addressed" My IPC 2222 has the following address on the SIF: IPC 300 Lakeside Drive, Suite 309S Bannockburn, IL 60015-1219 Is this where I should also send the 600 form???
