What is reverse geocoding?

Reverse geocoding is the process of converting GPS coordinates into a readable address, street or place. For example, "51.499403,-0.127362" becomes "Westminster Abbey, London, SW1P 3PA, United Kingdom".

Using the Swiftcomplete Reverse Geocoding API, you can convert a latitude, longitude into an accurate postal address, or generate a list of the closest addresses or places to a GPS coordinate.

Integrate the API or npm package in minutes with the reverse geocoding documentation & code samples.

How it works

Swiftcomplete's reverse geocoder works by searching for the closest matches to your provided coordinates. This is either calculated by straight-line distance, or by checking whether the coordinates are situated within a polygon (e.g. a country).

Depending on your use-case, reverse geocoding can operate at different levels of resolution or accuracy:

Address level

Exact address

Exact address level reverse geocoding
  • Coordinates for each individual property
  • Best possible data accuracy
  • Returns nearest postal address to your coordinates

Address range

Address range reverse geocoding
  • Range of house numbers on a street
  • Finds approximate house number
  • Works best where houses are spaced evenly on the street

Street level


Street level reverse geocoding
  • Finds the closest street to your coordinates
  • More accurate in countries where street polylines are available rather than centre-point coordinates

Place level


City & town reverse geocoding
  • Nearest city, town, village or suburb
  • Measured by distance to the centre-point of the locality


Postcode & ZIP code reverse geocoding
  • Closest postal code or ZIP code
  • Measured by distance to the centre-point of the postcode

Region level


State, county & admin area reverse geocoding
  • Nearest state, county or admin area
  • More accurate in countries where polygons are available rather than centre-point coordinates


Country reverse geocoding
  • Nearest country
  • More accurate where polygons are available rather than centre-point coordinates

Data availability varies by region. Less granular datasets (such as region level or place level) are more cost effective, whereas high-resolution address level datasets provide the best possible accuracy.
