I am an individual person (not employed at a developer studio or owning a business) living in Switzerland. I made my first iOS app with Unity that uses in-app-purchases (IAP) and to successfully implement them I need to provide the U.S. tax information in AppStore Connect. I have open questions in the linked screenshot regarding the form. Is it correct to choose SSN at point 5 and add 000000000 (9 x zero) in the space provided for the tax ID (point 6) like several online resources advice? What belongs to the field "Title"? etc. (link to the image)
Maybe you can give a more reliable feedback to this open questions as the Apple Reviewer suggested me to come here and ask. Thank you very much.
