Originally from ticket #2041.
While testing I found the registry agency code DE-AG for the
organisation: Fairtrade Labelling Organizations International
organisation ref: DE-AG-VR7795
After some investigation I found this organisation at
https://www.handelsregister.de with the organisation identifier VR 7795
So my suggestion is to add this registry agency.
AG could be a abbreviation of Ambtsgericht (I send a message to a friend
who had a company in Germany for several years to verify this).
Name: Gemeinsames Registerportal der Länder
