Wikipedia:Articles for deletion/Lists of ZIP Codes in the United States by state
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
