I need help addressing an envelope for a letter, it is going to London England, HELP
I know that might be a silly question but does anyone know how to address a letter to someone in London england the address is as follows:
PO Box XXXXXX
London
NW7 3ZU
HELP, do I address it London, England NW7 3ZU or do I put London under the NW7 3ZU and then London beneath it.:( I am confused, I thought that I would ask the post office but I really need to get this out ASAP, and BTW does this need special postage because it is going out of country? THANKS
