Related: can you expand it to include the reverse (geolocation to zip code)? Anyone know of a restful service that might do that, alternatively?

- lutusp 13y agoThat would be very difficult, and couldn't be made deterministic with a typical ZIP code database. The reason is most ZIP code databases list a geological position representing a location within the zone, but not its perimeter or geological extent. Therefore, converting from a geological position to a ZIP code would be a guessing game. Here's a typical ZIP code database entry: "74857","Newalla","OK","35.351612","-97.19507","-6","1" The fields are ZIP code, place name, state, latitude ("-" = south), longitude ("-" = west), time zone, location honors daylight time. So no size or shape for the zone itself, only a location within the zone. An algorithm might find the geographically nearest ZIP code position for a given argument position and return that result, but it would likely be wrong in many situations where there are a lot of ZIP codes, like urban areas.
- draz 13y agothat's actually good enough for my purposes :-) (I'm looking to get a zip code from the browser and then show stores, for example, in a 50 mile radius). 2 adjacent zip codes would still be around 50 miles from the store.
