I posted this previously. Let me know if your interested and I can share more details. Not based on zip code but based on a polygon.

I have a resource you might find interesting. Was used to build this here: Location Finder | Find Your Nearest JAE Branch | JAE

I can provide you with the code if you are interested. This uses a JS library, Turf, to pinpoint a location inside of a polygon.

Might be of some help.
