Ran into the “additional info” field in the addresses and I honestly don’t know what it’s for. I need to pick up and convey (and sometimes write to) the address and I’m just not sure what is supposed to go into that field.
I’m thinking that maybe people from the Netherlands would want to enter house extensions (they sometimes label the street address with “Streetname 1 red house” etc) and it could be used for that but I’m just not sure, can’t find it documented either.
People are very inventive they will find some use for that. you can imagine that someone is living at some frindes place. so he can add there information that the package or bill should be given to his friends name.
Then there are Dorms or Hotels were someone wants to provide his Room Number.
There are many more cases.
