Convert GPS coordinates into a readable address
Reverse geocoding is a process of converting geographic coordinates (latitude and longitude) into a human-readable address (such as country, state, city, and postal code ) with a high level of accuracy.
The reverse geocoding API is commonly used in location-based web and mobile apps. The most common use cases are hyper-localised content, customer/ads targeting, geoblocking, online games, mobile asset tracking, business intelligence, online fraud detection/security and many more.

UNIQUE METHODOLOGY
Why BigDataCloud?
BigDataCloud’s reverse geocoding API uses unique geocoding methods to derive super accurate rich locality information from a point location coordinates at a submillisecond response time.
The geocoder is the first to deliver administrative/non-administrative boundaries-based results. This makes the API a perfect fit for determining locality areas such as a suburb, city, state or country, rather than a street address.
BigDataCloud’s reverse geocoding API is much faster compared to other providers and has excellent support even for less populated areas.

Unique IP geolocation fall-back
In absence of geo-coordinates, the API will automatically use the client’s IP address for the location. It is backed up by the world's most accurate next-generation IP Geolocation technology (patent pending)
Better than 99.999% availability
Enterprise-grade redundant infrastructure. Operated from eight geographically diverse data centres across the globe

Technical Benefits
The blazingly fast response time, combined with the high-quality accurate location data, allows you to deliver location-based features on mobile or web with no compromise on data quality.
There is no need for an API key or account creation in order to use the API. This makes it super easy to implement on your project and worry less about API key security.
The client-side implementation of the API enables you to process user’s location data on the client’s device making your application GDPR compliant and more secure.
When the user does not share their geographical coordinates with your app or website, the API automatically uses the client’s IP address to resolve its location. This reduces the need to implement additional APIs and logic in your system. The API can become a useful extension of existing web and mobile geolocation APIs.
