Verifiability in OSM means *independent* verifiability based on 
observations of the geographic reality.  Same as with any other kind of 
proprietary ID.

That might depend on the country but AFAIK in many countries postal 
codes cover the whole country.

There are many addresses that do not receive postal delivery - in 
particular for example corporate infrastructure where mail is 
collectively delivered to a single location while individual buildings 
and other infrastructure still have their own addesses.

I have not made any suggestion as to what kind of address tag to use but 
if the plot number is signed and you invite your friends for a grilling 
party at plot 42 that is definitely an address from my perspective.
