i think u should start writeing ur add from 1st line

n when 1st line is full then fill the remaining add  in the 2nd line

n then in 3rd line

You can give the complete address in 1st address itself and leave other addresses  blank  if the number of characters doesn't exceed the limit.

Or else break your address and given it in second and third addresses. (it's 2nd and 3rd line of the same address)

No need to fill all the addresses if you can accommodate your address in 1 or 2 itself.
