So now you appear to be talking about the UK which I do know about and 
which definitely doesn't have boundaries as such.

Royal Mail as I understand it defines each post code by a list of 
addresses. They do also provide a centroid point derived from that list 
but I don't believe they provide any sort of boundary.
