It seems you simply don't want to agree that physical location is not
the ideal routing criterium for things like mail.  That is fine, but
please don't think that you can reform the postal system by proposing
such a simple thing that of course has been though of long before.

(as I already mentioned, a system just like the one you propose is in
use by radio amateurs for several years.  they use if for purposes like
heading and distance calculations, where your simple formulas work)

When you need all kinds of "exception" and "organizational border" data
to derive routing from your system, it is clear that you are on the wrong
way.  The existing postal code has this routing information already
built in, and considering that the postal code is *designed* to make
mail routing possible, that is what one expects.  It is not so interesting
to know where a location exactly is, as long as you know how to get there.
