Reverse Geocode


Creates addresses from point locations in a feature class. The reverse geocoding process searches for the nearest address or intersection for the point location based on the specified search distance. When using the ArcGIS World Geocoding Service, this operation may consume credits.


  • The input feature class must contain point shapes with valid x,y coordinates. Addresses will not be returned on points with null coordinates.

  • The output feature class will contain the same number of records as in the input feature class. Additional fields containing the result addresses are added to the feature class. The names of the fields are prefixed with REV_. If an address cannot be found, the fields will contain empty values.

  • If the spatial reference of the input feature class is different from the address locator, the address locator will transform the coordinates on the fly and try to find the match. The output feature class will be saved in the same spatial reference as the input feature class. Changing the spatial reference of the output feature class is possible by setting a different output coordinate system in the tool's environment settings.

  • If a point in the input feature class fails to return an address, it means there are no features in the address locator that can be associated with the input point. Here are a few common causes for the unmatched points:

    • The search distance is so small that the point cannot find any nearest features.
    • The point contains null coordinates.
    • The point's coordinates are incorrect and cannot be transformed to the spatial reference used in the address locator.
    • The address locator does not contain reference features in the area that can be associated with the point.

    You can increase the search distance so that the chance to find the nearest address is higher, or use a different address locator that contains more features or covers a larger area to match the input points.

  • An ArcGIS Online for organizations subscription is required if you reverse geocode a feature class using the ArcGIS World Geocoding Service.


ReverseGeocode_geocoding (in_features, in_address_locator, out_feature_class, {address_type}, search_distance, {feature_type}, {location_type})
ParameterExplanationData Type

A point feature class or layer from which addresses are returned based on the features' point location.

Feature Layer

The address locator to use to reverse geocode the input feature class or layer.

Address Locator

The output feature class.

Feature Class

Indicates whether to return addresses for the points as street addresses or intersection addresses if the address locator supports intersection matching.

  • ADDRESSReturns street addresses or in the format defined by the input address locator. This is the default option.
  • INTERSECTIONReturns intersection addresses. This option is available if the address locator supports matching intersection addresses.

The distance used to search for the nearest address or intersection for the point location. Some locators use optimized distance values that do not support overriding the search distance parameter.

Linear Unit

Limits the possible match types returned. Single or multiple values can be selected. If a single value is selected, the search tolerance for the input feature type is 500 meters. If multiple values are included, the default search distances specified in the feature type hierarchy table are applied. See the REST API web help for more details about the featureTypes parameter for reverseGeocode.

This parameter is not supported for all locators.

  • POINT_ADDRESSA street address based on points that represent house and building locations.
  • STREET_ADDRESSA street address that differs from Point Address because the house number is interpolated from a range of numbers. Street Address matches include the house number range for the matching street segment rather than the interpolated house number value.
  • STREET_INTERSECTIONA street address consisting of a street intersection along with city and optional state and postal code information. This is derived from Street Address reference data, for example, Redlands Blvd & New York St, Redlands, CA, 92373.
  • LOCALITYA place-name representing a populated place.
  • POSTALA postal code. Reference data is postal code points, for example, 90210 USA.
  • POINT_OF_INTERESTA point of interest. Reference data consists of administrative division place-names, businesses, landmarks, and geographic features, for example, Starbucks.
  • DISTANCE_MARKER A street address that represents the linear distance along a street, typically in kilometers or miles, from a designated origin location, for example, Mile 25 I-5 N, San Diego, CA.

Specifies the preferred output geometry for POINT_ADDRESS matches. The options for this parameter are ROUTING_LOCATION, the side of street location, which can be used for routing, or ADDRESS_LOCATION, the location that represents the rooftop, parcel centroid for the address, or front door. If the preferred location does not exist in the data, the default location of ROUTING_LOCATION will be returned instead. For geocode results with Addr_type=PointAddress, the x,y attribute values describe the coordinates of the address along the street, while the DisplayX and DisplayY values describe the rooftop or building centroid coordinates. See the REST API web help for more details about the locationType parameter for reverseGeocode.

This parameter is not supported for all locators.

  • ADDRESS_LOCATIONReturns geometry for geocode results that represent an address location such as rooftop, building centroid, or front door.
  • ROUTING_LOCATIONReturns geometry for geocode results that represent a location close to the side of the street, which can be used for vehicle routing. This is the default.

Code sample

ReverseGeocode example (Python window)

The following Python window script demonstrates how to use the ReverseGeocode function in immediate mode.

import arcpy

arcpy.env.workspace = "C:/data/locations.gdb"

# Set local variables:
input_feature_class = "customers"
address_locator = "e:/StreetMap/data/Street_Addresses_US"
result_feature_class = "customers_with_address"

arcpy.ReverseGeocode_geocoding(input_feature_class, address_locator, 
                               result_feature_class, "ADDRESS", "100 Meters")
