when did the united states start using zip codes?
1970
if onoville had ever been assigned a zip code, it would have likely been 14764, as gaps in the united states postal service's online database have zip codes 14761 to 14764 missing, with a town name somewhere alphabetically between olean and oramel; as olean is substantially larger and zip codes 14761 through 14763 were likely reserved for it but never used, it is unknown whether 14764 was reserved for olean or onoville). if the zip code had been assigned, it likely was never used, since by the time zip codes were rolled out outside the cities in 1963, the kinzua dam was already being built. the onoville post office closed june 30, 1964.

zip codes may not currently be used to identify existing legislative districts. although the website of the u.s. house of representatives has a "find your representative" feature that looks up congressional districts based on zip codes alone, it often returns multiple districts corresponding to a single zip code. this is because different parts of one zip code can be in different districts. one proposal to eliminate the possibility of extreme partisan gerrymandering calls on using zip codes as the basic units for redistricting.
