My company, though not a corporation or LLC, is officially registered with the Oregon Department of Corporations and has an official certificate which allows contracting with the state. This is not a county DBA; the term DBA does not appear.
Can my company name be my app publication name in the app store?
I actually formed a limited company specifically so that I would get a company name in the app store, rather than my personal name.
Of course as soon as I did that, Apple stopped showing the developer name under the app name in the app store, and instead show a new "subtitle" or "promotional text"....
The result has been an increase in bureaucracy in my life and zero change in sales.
