Deletion of Lists of ZIP Codes in the United States by state

Comment: per After Midnight and per Cryptic.  I work for a geodemographics company and I can confirm that ZIP Code information is not changed on fixed schedules like FIPS state/county codes or Census Bureau tract/block-group/block codes.  #Wikipedia is not a directory and this would be impractical to maintain even if no vandals ever edited it.  No prejudice against creation of a well-sourced article ''about'' the ZIP Code system, without directory-type information, per Norotin

Comment: This listing is simply not akin to the examples listed in #DIR.  The entries on the list are individually notable in the same way that List_of_towns|localities, List_of_rivers_by_length|rivers, and List_of_interstate_highways|highways are, and probably more notable than such information as List_of_U.S._county_birds|county birds.  But, more importantly, ZIP codes are a systematic and widely-used way to divide up the United States geographically; ZIP codes themselves are in widespread use, and the system itself is notable.  I know of no other online, centralized repository where it's easy and free of charge to get a list of all ZIP codes and/or see how they are organized; one can query databases like that at http://www.usps.com the Post Office website, but that won't show all the ZIP codes in an organized fashion.  The per-state lists are a logical and useful hierarchical addition to the main ZIP code page.  This is of general interest--why delete it on disputed aesthetic grounds

Comment: I agree that the issue is larger, but I am trying to take this group of articles as a manageable bite.  It was my opinion per  that adding more articles to the mix would muddy the issue and potentially split discussion into keep some and delete others.  After this group is done, other appropriate groupings may be addressed referencing this discussion
