In my mind it makes sense for a UK address form to contain 3 address lines. There are instances of people living in blocks or buildings where 2 lines may not always be enough.
I just wondered if anyone had any thoughts and/or guidance on this, should a UK address form have 2 or 3 address lines fields?
Best practice and thoughts are all welcome.
For the address itself, there should be 4 lines as explained on the clear addressing guidelines on the official Royal Mail website (I say for the address itself because there is 4 + 1 line for the addressee's name).
EDIT : Some people have pointed out to me that you sometimes need to indicate the house name before the street name, so 5 lines instead of 4 finally !
