Reverse Geocode

Service version: 2
Last edit: 2022.11.14

Purpose

The TomTom Reverse Geocoding API gives users a tool to translate a coordinate (for example: 37.786505, -122.3862) into a human-understandable street address, street element, or geography. Most often, this is needed in tracking applications where you receive a GPS feed from the device or asset and you want to know the address.

The type of response depends on the available data:

  • address: Returns the most detailed information.
  • street element: Less detailed returned when there is no address data.
  • geography: Returns the smallest available geographic data.
    • This is returned when there is no address or street element data.
    • You can specify the level of geography (see the entityType parameter in the request parameters section) to get a geometry.
    • The geometry data can be fetched using the Additional Data service.

Run this endpoint

You can easily run this and other endpoints. Go to the TomTom API Explorer page and follow the directions.

mapcode object

Field Description
type
string

Type of mapcode. Possible values:


Local:
The shortest possible (and easiest to remember) mapcode. Local mapcodes are especially useful when the user knows what territory the mapcode is in (for example, when an application is designed to be used inside just one European country or US state). Note that the code element of a Local mapcode is ambiguous when used without the territory element - e.g.,: the "4J.P2" mapcode can mean the Eiffel Tower location (48.858380, 2.294440) (with the territory set to FRA), but also some place in Amsterdam-Noord, Netherlands (52.382184, 4.911021) (with the territory set to NLD).


International:
This mapcode is unambiguous. It is also the longest.


Alternative:
Alternatives to Local mapcodes. Each Alternative mapcode points to slightly different coordinates due to the way mapcodes are computed (see the mapcode documentation ). For example: the position from a response can be encoded as "5DM.WC" (51.759244, 19.448316) and the "VHJ.036" (51.759245, 19.448264), which are close to each other, but not exactly the same place.

fullMapcode
string

The full form of a mapcode (territory + code). It is always unambiguous. The territory element is always in the Latin alphabet. In an International mapcode, the territory part is empty.

territory
string

The territory element of the mapcode. The territory element is always in the Latin alphabet. Usually, the territory is the

ISO 3166-1 alpha 3

abbreviation for the country name. However in these eight very large countries:

  • The USA,
  • Canada,
  • Mexico,
  • Brazil,
  • India,
  • Australia,
  • Russia,
  • China

an address has little meaning unless the user also knows what state it's in (just as, elsewhere, an address has little meaning if the user doesn’t know what country it’s in). More information about territory codes is available at

Territories for mapcodes

. This field is not returned for an International mapcode.

code
string

The mapcode without the territory element. It consists of two groups of letters and digits separated by a dot. The code is using the same language and alphabet as the response. The language parameter may be used to modify the language and alphabet of both the response and the code (for example: Cyrillic for the language 'ru-RU'). This field is not returned for the International mapcodes - use fullMapcode instead.

Default view mapping

Default view is recognized based on the country the request came from.
