[SFDXA] FRANK'S COMPULSIVE GUIDE TO POSTAL ADDRESSES

[WILLIAM MARX]

  Effective Addressing for International Mail
This document tries to describe – or invent when necessary – conventions for 
addressing postal mail from within the USA to other countries that are both (a) 
effective (i.e. have a good chance of working), and (b) as inoffensive as 
possible when addressing choices might be controversial. Note that the general 
problem – how to address mail from country A to country B, for all A's and B's – 
is an n × n problem, of which this document attempts to address only one 
dimension: mail from the USA to elsewhere. But even this is a moving target as 
addressing guidelines and formats of each country are constantly revised.
