In Norway it is very common that your slip road is into another street
than your adress to the house. But it is not possible to mark your slip road from another street than the adress street. It should !
It's also happening that the house numbers are not in order
here in Norway. It can be number 22, 24, 28, 26... Depends on... You know, there are a lot of hills in Norway, and some times you have to drive around a little hill to get to the street. Then... If you live in number 28, it can happend that your slip road enter the street between 24 and 26. There must be a possibility to do that.
And I have had a third problem when adding house numbers:
It's common in Norway to have a letter behind the house number
. For example when 3 houses (or more) have the same slip road down to the street. Those house numbers can be 28A, 28B, 28C etc... It must be possible to enter a letter behind the number !
