    What is reverse geocoding?

    Reverse geocoding is the process of turning 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.

    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.
