Geocode Addresses

Summary

Geocodes a table of addresses. This process requires a table that stores the addresses you want to geocode and an address locator or a composite address locator. This tool matches the addresses against the locator and saves the result for each input record in a new point feature class. When using the ArcGIS World Geocoding Service, this operation may consume credits.

Usage

  • You can geocode addresses that are stored in a single field or are split into multiple fields. A single input field stores the complete address, for example, 303 Peachtree St NE, Atlanta, GA 30308. Multiple fields are supported if the input addresses are split into multiple fields, such as Address, City, State, and ZIP for a general United States address.

  • Some locators support multiple input address fields, such as Address, Address2, and Address3. In this case, the address component can be separated into multiple fields, and the address fields will be concatenated together at the time of geocoding. For example, 100, Main st, and Apt 140 across three fields, or 100 Main st and Apt 140 across two fields, would both become 100 Main st Apt 140 when geocoding.

  • The output feature class is saved in the same spatial reference as the address locator. Changing the spatial reference of the output feature class is possible by setting a different output coordinate system in the tool's environment settings.

  • The output feature class, by default, stores a copy of the input address and additional information such as score, status, and matched address of each record. The addresses can be rematched using the Rematch Addresses tool or the Rematch Addresses option that opens the Rematch Addresses pane. Editing addresses in the input address table will not change the result in the output feature class once the matching process finishes and the feature class is created.

  • An ArcGIS Online for organizations subscription is required to match a table of addresses using the ArcGIS World Geocoding Service.

Syntax

GeocodeAddresses_geocoding (in_table, address_locator, in_address_fields, out_feature_class, {out_relationship_type}, {country}, {location_type}, {category})
ParameterExplanationData Type
in_table

The table of addresses to geocode.

Table View
address_locator

The address locator to use to geocode the table of addresses.

Note:

Including the .loc extension after the locator name at the end of the locator path is optional.

Address Locator
in_address_fields
[input_address_field, table_field_name]

Each field mapping in this parameter is in the format input_address_field, table_field_name where input_address_field is the name of the input address field specified by the address locator, and table_field_name is the name of the corresponding field in the table of addresses you want to geocode.

You can specify one single input field that stores the complete address, for example, 303 Peachtree St NE, Atlanta, GA 30308. Alternatively, you can also specify multiple fields if the input addresses are split into multiple fields such as Address, City, State, and ZIP for a general United States address.

Some locators support multiple input address fields, such as Address, Address2, and Address3. In this case, the address component can be separated into multiple fields, and the address fields will be concatenated together at the time of geocoding. For example, 100, Main st, and Apt 140 across three fields, or 100 Main st and Apt 140 across two fields, would both become 100 Main st Apt 140 when geocoding.

If you choose not to map an optional input address field used by the address locator to a field in the input table of addresses, specify that there is no mapping by using <None> in place of a field name.

Field Info
out_feature_class

The output geocoded feature class or shapefile.

Feature Class
out_relationship_type
(Optional)

This parameter has no effect in ArcGIS Pro. It remains to support backward compatibility with ArcGIS Desktop. In ArcGIS Pro, the only permissible value is STATIC.

  • STATICCreates a static copy of the fields input address table in the output feature class. This is the only permissible value.
  • DYNAMICThis option is not applicable in ArcGIS Pro. See ArcGIS Desktop help for this tool.
Boolean
country
[country,...]
(Optional)

This parameter is available for locators that support a country parameter and will limit geocoding to the selected countries. Making a country selection will improve the accuracy of geocoding in most cases. If a field representing countries in the Input Table is mapped to the Country Input Address Field, the country value from the Input Table will override the Country parameter.

This is limited to the selected country or countries, and when no country is specified, geocoding is performed against all supported countries of the locator. The input value should be specified as ISO 3166-1 3-character country codes.

Country is not supported for all locators.

String
location_type
(Optional)

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 location, parcel 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.
String
category
[category,...]
(Optional)

Limits the types of places the locator searches, thus eliminating false positive matches and potentially speeding up the search process. When no category is used, geocoding is performed against all supported categories. Not all category values are supported for all locations and countries. In general, the parameter can be used for the following:

  • Limit matches to specific place types or address levels
  • Avoid fallback matches to unwanted address levels
  • Disambiguate coordinate searches

This parameter is not supported for all locators.

See the REST API web help for details about category filtering.

Code sample

GeocodeAddresses example (Python window)

The following Python window script demonstrates how to use the GeocodeAddress function to geocode a table of addresses.

import arcpy

arcpy.env.workspace = "C:\ArcTutor\Geocoding\atlanta"

# Set local variables:
address_table = "customers.dbf"
address_locator = "Atlanta_AddressLocator"
address_fields = "Street Address;City City;State State;ZIP Zip"
geocode_result = "geocode_result.shp"

arcpy.GeocodeAddresses_geocoding(address_table, address_locator, address_fields, 
                                 geocode_result, 'STATIC')
