Reverse Geocoding

Reverse geocoding generates an address from a latitude and longitude or from an OSM object.


The main format of the reverse API is<query>

There are two ways how the requested location can be specified:

  • lat=<value> lon=<value>

    A geographic location to generate an address for. The coordiantes must be in WGS84 format.

  • osm_type=[N|W|R] osm_id=<value>

    A specific OSM node(N), way(W) or relation(R) to return an address for.

In both cases exactly one object is returned. The two input paramters cannot be used at the same time. Both accept the additional optional parameters listed below.

Output format

  • format=[xml|json|jsonv2|geojson|geocodejson]

See Place Output Formats for details on each format. (Default: html)

  • json_callback=<string>

Wrap json output in a callback function (JSONP) i.e. <string>(<json>). Only has an effect for JSON output formats.

Output details

  • addressdetails=[0|1]

Include a breakdown of the address into elements. (Default: 1)

  • extratags=[0|1]

Include additional information in the result if available, e.g. wikipedia link, opening hours. (Default: 0)

  • namedetails=[0|1]

Include a list of alternative names in the results. These may include language variants, references, operator and brand. (Default: 0)

Language of results

  • accept-language=<browser language string>

Preferred language order for showing search results, overrides the value specified in the "Accept-Language" HTTP header. Either use a standard RFC2616 accept-language string or a simple comma-separated list of language codes.

Result limitation

  • zoom=[0-18]

Level of detail required for the address. Default: 18. This is a number that corresponds roughly to the zoom level used in map frameworks like Leaflet.js, Openlayers etc. In terms of address details the zoom levels are as follows:

zoom address detail
3 country
5 state
8 county
10 city
14 suburb
16 street
18 building

Polygon output

  • polygon_geojson=1
  • polygon_kml=1
  • polygon_svg=1
  • polygon_text=1

Output geometry of results as a GeoJSON, KML, SVG or WKT. Only one of these options can be used at a time. (Default: 0)

  • polygon_threshold=0.0

Simplify the output geometry before returning. The parameter is the tolerance in degrees with which the geometry may differ from the original geometry. Topology is preserved in the result. (Default: 0.0)


  • email=<valid email address>

If you are making large numbers of request please include an appropriate email address to identify your requests. See Nominatim's Usage Policy for more details.

  • debug=[0|1]

Output assorted developer debug information. Data on internals of Nominatim's "Search Loop" logic, and SQL queries. The output is (rough) HTML format. This overrides the specified machine readable format. (Default: 0)
