Gps2zip

Convert GPS latitude longitude pairs to a US zip code.

Quick Start

npm install gps2zip

Usage

var gps = require('gps2zip');
var latitude = 30.2669;
var longitude = 97.7428;
gps.gps2zip(latitude, longitude);
// returns 78701

Unit tests

node tests/basic.js

Accuracy

The output is approximate. The source data is just a list of coordinates, not actual boundaries. The algorithm just finds the minimum euclidean distance between the point in question and the known points. No error checking for points outside the United States.
