boundaries-io API Overview

US Zipcode, County, City, and State Boundaries API:

A simple & very fast API that will allow you to integrate multiple GeoJson US boundaries results into your apps and systems.

This API is designed to be used programatically for optimal performance. When using the MashApe UI for queries expect significant latency issues on large result sets!

US Boundaries as GeoJson(City,State,ZipCode)

We use 2016 US Census/TIGER data from the United States Government and other data sources to populate our repositories.

Our infrastructure consists of multiple servers across the united states in the cloud, so we guarantee 99.9% up time while using our service.

  1. Test the API

  2. Copy and paste the results here: to see a sample of how to integrate with googlemaps. This API is designed to be used programatically for optimal performance. When using the MashApe UI for testing queries expect significant latency issues and "API not responding errors", or Downloading hangs at 100% (MashApe UI) on large result sets if you set the limit over 50 zipcodes! By Removing the limit parameter sets no limit in the number of zipcodes returned for your query.

This does not happen with direct calls to the API.

NO HARVESTING ,or you account will be blocked. Please do not attempt to harvest data via the API:
