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.

zctas are generalized area representations of the united states postal service (usps) zip code service areas, but are not the same as zip codes. individual usps zip codes can cross state, place, county, census tract, census block group and census block boundaries, so the census bureau asserts that "there is no correlation between zip codes and census bureau geography". moreover, the usps frequently realigns, merges, or splits zip codes to meet changing needs. these changes are usually not reflected in the annual tiger releases. each zcta is constructed by aggregating the census 2010 blocks whose addresses use a given zip code. in assembling census statistical units to create zctas, the census bureau took the zip code used by the majority of addresses in each census unit at the time the data was compiled. as a result, some addresses end up with a zcta code that is different from their zip code. zctas are not developed for zip codes that comprise only a small number of addresses. several zctas represent zips that no longer exist due to realignment by the usps.
