Address locators can be created in any file folder you specify.
The role of a reference dataset defines the role that it plays as reference data for the address locator. The address locator styles provided with ArcGIS use the following values to describe the roles of reference datasets:
- Primary table—Defines the primary reference dataset feature class for a locator, such as a street centerline feature class. This is a required table.
- Alternate City Name table—Defines an alternate city name table that contains alternate names for the city or place name. The table is required to have a JoinID that can be used to join to the primary table. This table is optional.
- Alternate Name table—Defines an alternate street name table that contains alternate names for the street or point features. The table is required to have a JoinID that can be used to join to the primary table. This table is optional.
- Alias table—Defines a place name alias table that contains place names and actual addresses for the names. User can find the location using either the place name such as Field Museum or the address 1400 S Lakeshore Drive Chicago, IL 60605. This table is optional.
Custom locator styles or locator styles provided by third parties may define different roles for reference data feature classes and tables. Refer to their documentation for information on the roles that they define for reference datasets.
Composite address locators cannot be created using this tool. Use the Create Composite Address Locator tool to create a composite address locator.

Syntax

Parameter	Explanation
in_address_locator_style	The address locator style on which to base the new address locator. US Address-Dual Ranges—Use when the reference data is a line feature class that contains house number ranges on both sides of a street segment, and you want to search for an address on a specific side of the street or a street intersection. US Address-One Range—Use when the reference data is a line feature class with one house number range for each road segment, and you want to search for an address (where side is not needed) or a street intersection. US Address-Single House—Use when the reference data is a point or polygon feature class where each feature represents a single address, and you want to search for an exact address for a parcel, building, or address point. US Address-Single House Subaddress—Use when the reference data is a point or polygon feature class where each feature represents a single address with optional subaddress elements, and you want to search for apartment units, townhouses, duplexes, or stores in a shopping plaza. US Address-Street Name—Use when the reference data is a line feature class, and you want to search for addresses using only the street name. Address range information is not required. US Address-City State—Use when the reference data is a point or polygon feature class, and you want to search for a specific city in a state. US Address-ZIP 5 Digit—Use when the reference data is a point or polygon feature class where each feature represents a ZIP Code centroid or geographic area, and you want to search for a specific ZIP Code location. General-Gazetteer—Use when the reference data is a point or polygon feature class where each feature represents any unique feature, and you want to search for a place-name, landmark, water meter, or any unique value.
in_field_map	The mapping of reference data fields used by the address locator style to fields in the reference datasets. Fields with an asterisk (*) next to their names are required by the address locator style. To determine the alias name for a reference data field used by a locator style, open the Create Address Locator tool dialog box and choose the locator style. The name that appears in the Field Name column of the Field Map control is the field's alias name.
config_keyword (Optional)	The configuration keyword that determines the storage parameters of the table in a Relational Database Management System (RDBMS)—enterprise and file geodatabases only.
enable_suggestions (Optional)	Allows character-by-character auto-complete suggestions to be generated for user input in a client application. This capability facilitates the interactive search user experience by reducing the number of characters that need to be typed before a suggested match is obtained. The idea is that a client application can provide a list of suggestions which is updated with each character entered by a user until the place they are looking for is returned in the list. Only the locator styles provided by Esri can be used to build locators with suggestions enabled. The suggestion functionality is only exposed when such a locator is published as a geocode service. Locators with suggestions enabled can only be saved in a file folder; they cannot be saved in a geodatabase. Checked—Suggestions are enabled for the locator. Unchecked—Suggestions are disabled for the locator. This is the default.
