FREE Client Side Reverse Geocoding to City API

Introduction

Reverse geocoding is the process of back (reverse) coding of a point location (Latitude, Longitude) to a readable address or a place.

Existing reverse geocoding providers look for the closest street address for the provided coordinates. In most use-cases, this level of detail is overkill, providing an incredibly slow service of minimal accuracy, with quality that varies wildy for mobile and regional users.

Our Reverse Geocoding API is the first to deliver administrative/non-administrative boundaries-based results and as such, it is the perfect choice when you need to resolve a user's practical area such as their city, state or country rather than their street address.

A prime use-case is when utilising client-side W3C geolocation and you need to recognise your customer's closest outlet, or what promotions are available in their region.

Our reverse geocoding API not only offers detailed locality information based on your customer's Latitude & Longitude, it is also exceptionally fast with each response being generated with sub-millisecond timing, allowing for true real-time applications.

This client-side API is completely FREE for both commercial and non-commercial use, including unlimited usage with no throttling or limitations.

No credit card or account is required, simply implement using the instructions below to get started.

 

Important! This particular API is for client-side use only. Any user found abusing this service by implementing it server-side will be blacklisted from all of our free Api Services. If you wish to utilise this Reverse Geocoding API in your backend applications, please visit our server-side variation of this API for pricing details.
