Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nAddress descriptors include additional information that help describe a location\nusing landmarks and areas. Check out the [address descriptors demo](https://mapsplatform.google.com/demos/address-descriptors/)\nto explore the feature.\n| **Note:** Address descriptors are more useful in denser locations. If there are no relevant landmarks or areas the response may be empty. Some regions don't have detailed area data and will return landmarks only.\n\nAdditional parameters\n---------------------\n\nAddress descriptors can be enabled through the use of the `extra_computations`\nparameter. Include `extra_computations=ADDRESS_DESCRIPTORS` in a [geocoding request](/maps/documentation/geocoding/requests-geocoding)\n, [reverse geocoding request](/maps/documentation/geocoding/requests-reverse-geocoding)\n, or a [places geocoding request](/maps/documentation/geocoding/requests-places-geocoding)\nto receive address descriptors in your response.\n\nExample in geocoding\n--------------------\n\nThe following query contains the address of a place in Delhi: \n\n https://maps.googleapis.com/maps/api/geocode/json?address=4118,+Kalan+Mehal+Chandni+Chowk,+New+Delhi&extra_computations=ADDRESS_DESCRIPTORS&key=YOUR_API_KEY\n\nExample in places geocoding\n---------------------------\n\nThe following query contains the place ID of a place in Delhi: \n\n https://maps.googleapis.com/maps/api/geocode/json?place_id=ChIJyxAX8Bj9DDkRgBfAnBYa66Q&extra_computations=ADDRESS_DESCRIPTORS&key=YOUR_API_KEY\n\n| **Note**: Not all places are compatible with address descriptors. Very large places (for example, an airport) or areas (for example, a postal region) will never receive an address descriptor.\n\nExample in reverse geocoding\n----------------------------\n\nThe following query contains the latitude/longitude value for a location in\nDelhi: \n\n https://maps.googleapis.com/maps/api/geocode/json?latlng=28.640964,77.235875&extra_computations=ADDRESS_DESCRIPTORS&key=YOUR_API_KEY\n\n| **Note**: Reverse geocoding includes a single address descriptor at the response level. Geocoding and places geocoding will receive an address descriptor for each compatible result in the response\n\n### Response\n\nAn example `address_descriptor` is as follows: \n\n {\n \"address_descriptor\" : {\n \"areas\" : [\n {\n \"containment\" : \"OUTSKIRTS\",\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"Turkman Gate\"\n },\n \"place_id\" : \"ChIJ_7LLvyb9DDkRMKKxP9YyXgs\"\n },\n {\n \"containment\" : \"OUTSKIRTS\",\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"Chandni Chowk\"\n },\n \"place_id\" : \"ChIJWcXciBr9DDkRUb4dCDykTwI\"\n },\n {\n \"containment\" : \"NEAR\",\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"Katar Ganj\"\n },\n \"place_id\" : \"ChIJH3cWUyH9DDkRaw-9CjvcRvY\"\n }\n ],\n \"landmarks\" : [\n {\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"Delite Cinema\"\n },\n \"straight_line_distance_meters\" : 29.9306755065918,\n \"place_id\" : \"ChIJLfiYDCT9DDkROoEa7NdupUM\",\n \"travel_distance_meters\" : 418.7794799804688,\n \"spatial_relationship\" : \"ACROSS_THE_ROAD\",\n \"types\" : [ \"establishment\", \"movie_theater\", \"point_of_interest\" ]\n },\n {\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"YES Bank\"\n },\n \"straight_line_distance_meters\" : 66.83731079101562,\n \"place_id\" : \"ChIJFYHM3yb9DDkRRKGkZl2mpSQ\",\n \"travel_distance_meters\" : 489.0340270996094,\n \"spatial_relationship\" : \"DOWN_THE_ROAD\",\n \"types\" : [ \"bank\", \"establishment\", \"finance\", \"point_of_interest\" ]\n },\n {\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"UCO Bank\"\n },\n \"straight_line_distance_meters\" : 25.38849639892578,\n \"place_id\" : \"ChIJ-c6_wCb9DDkRjIk1LeqRtGM\",\n \"travel_distance_meters\" : 403.2246398925781,\n \"spatial_relationship\" : \"ACROSS_THE_ROAD\",\n \"types\" : [ \"atm\", \"bank\", \"establishment\", \"finance\", \"point_of_interest\" ]\n },\n {\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"Delhi By Cycle Meeting Point\"\n },\n \"straight_line_distance_meters\" : 44.02867126464844,\n \"place_id\" : \"ChIJNxVfkSb9DDkRJD22l-eGFdM\",\n \"travel_distance_meters\" : 97.41281890869141,\n \"spatial_relationship\" : \"AROUND_THE_CORNER\",\n \"types\" : [\n \"establishment\",\n \"point_of_interest\",\n \"tourist_attraction\",\n \"travel_agency\"\n ]\n },\n {\n \"display_name\" : {\n \"language_code\" : \"en\",\n \"text\" : \"Axis Bank Branch\"\n },\n \"straight_line_distance_meters\" : 102.3495178222656,\n \"place_id\" : \"ChIJr3uaDCT9DDkR8roHTVSn1x4\",\n \"travel_distance_meters\" : 330.8566284179688,\n \"spatial_relationship\" : \"DOWN_THE_ROAD\",\n \"types\" : [ \"bank\", \"establishment\", \"finance\", \"point_of_interest\" ]\n }\n ]\n }\n }\n\nThere are two arrays in each `address_descriptor` object: `landmarks` and\n`areas`. The `landmarks` array contains up to 5 results ranked in order of\nrelevance by taking account of proximity to the requested coordinate, the\nprevalence of the landmark and its visibility. Each landmark result contains the\nfollowing values:\n\n- `place_id` is the place ID of the landmarks result. See the [place ID\n overview](/maps/documentation/places/web-service/place-id).\n- `display_name` is the display name of the landmark and contains `language_code` and `text`.\n- `straight_line_distance_meters` is the point to point distance in meters between the input coordinate and the landmarks result.\n- `travel_distance_meters` is the distance in meters as traveled via the road network (ignoring road restrictions) between the input coordinate and the landmarks result.\n- `spatial_relationship` is the estimated relationship between the input coordinate and the landmarks result:\n - `\"NEAR\"` is the default relationship when none of the following applies.\n - `\"WITHIN\"` when the input coordinate is contained within the bounds of the structure associated with the landmark.\n - `\"BESIDE\"` when the input coordinate is directly adjacent to the landmark or landmark's access point.\n - `\"ACROSS_THE_ROAD\"` when the input coordinate is directly opposite of the landmark on the other side of the route.\n - `\"DOWN_THE_ROAD\"` when the input coordinate is along the same route as the landmark, but not `\"BESIDES\"` or `\"ACROSS_THE_ROAD\"`.\n - `\"AROUND_THE_CORNER\"` when the input coordinate is along a perpendicular route as the landmark (restricted to a single turn).\n - `\"BEHIND\"` when the input coordinate is spatially close to the landmark, but far from its access point.\n- `types` are the [Place types](/maps/documentation/places/web-service/supported_types#table1) of the landmark.\n\nThe `areas` object contains up to 3 responses and limits itself to places that\nrepresent small regions, such as neighborhoods, sublocalities, and large\ncomplexes. Areas that contain the requested coordinate are listed first and\nordered from smallest to largest. Each `areas` result contains the following\nvalues:\n\n- `place_id` is the place ID of the areas result. See the [place ID\n overview](/maps/documentation/places/web-service/place-id).\n- `display_name` is the display name of the area and contains `language_code` and `text`.\n- `containment` is the estimated containment relationship between the input coordinate and the areas result:\n - `\"NEAR\"` is the default relationship when none of the following applies.\n - `\"WITHIN\"` when the input coordinate is close to the center of the area.\n - `\"OUTSKIRTS\"` when the input coordinate is close to the edge of the area.\n\n### Coverage\n\nAddress descriptors are available in all regions. See\n[region\ncoverage](/maps/documentation/geocoding/address-descriptors/coverage) for details.\n\n### Feedback\n\nThis feature is available in all regions and is in GA for India and in the\npre-GA Experimental launch stage for all other regions. We would appreciate\nfeedback. Please email us at [address-descriptors-feedback@google.com](mailto:address-descriptors-feedback@google.com)."]]
