RE: Normalization was Left AS/400 and Returned

Regarding zip+4, the extra 4 digits can also be a PO box number (PO Box
102 would be represented by xxxxx-0102).  I don't know if the USPS
refrains from overlap between street addresses and PO boxes or not.  I
don't see how it logically can, since it's not too dificult to have 100+
PO boxes in a single zip.  And a zip that large would likely have many
unique addresses as well.

So do rural routes/stops impact this discussion as well?

Maybe it's just plain easier to store c/s/z.  Plus, it probably makes
storing international addresses in the same db easier as they should map
to city/province/postal code.

I supposed every post office had its own zipcode.  Some towns have more
than one post office, but is there a place where towns share a post
office?



But beyond that, doesn't zip + 4 give you right down to the apartment
number and street?
