Primary Match IDs<\/strong><\/p>\n Addresses can have multiple names for a street or city, one is primary, and others are alternates. In this example ” Main Street ” is the primary name for a particular street, but it may also be known as “Highway 123”.\u00a0 Using the returnPrimaryMatchID<\/a> parameter, end users will have an experience where the service response will return \u201cHighway 123\u201d when the input address contains \u201cMain Street\u201d.<\/p>\n Comprehensive Zone Matching<\/strong><\/p>\n For cases when a user is unsure of a city name because an address is near a boundary between two cities, ArcGIS geocoding can still find the address. This fuzzy capability is enabled by default for the Geocoding Service and can now be disabled using the comprehensiveZoneMatch<\/a> parameter.<\/p>\n We are introducing several new parameters to customize the presentation of results for sub address suggestions. This will allow you to create customized user experiences.<\/p>\n Display all subaddresses at a location<\/strong><\/p>\n With the subaddressAfterBaseAddress<\/a> parameter, users will see a full list of apartments\u00a0that belong to an input address, such as \u201c3700 Dean Dr\u201d.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2942410,"id":2942410,"title":"SubAddressAfterBase","filename":"SubAddressAfterBase.png","filesize":11314,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/platform\/developers\/arcgis-geocoding-service-discover-whats-new\/subaddressafterbase","alt":"","author":"8632","description":"","caption":"","name":"subaddressafterbase","status":"inherit","uploaded_to":2942409,"date":"2025-10-09 00:42:06","modified":"2025-10-09 00:42:06","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":256,"height":238,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","medium-width":256,"medium-height":238,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","medium_large-width":256,"medium_large-height":238,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","large-width":256,"large-height":238,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","1536x1536-width":256,"1536x1536-height":238,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","2048x2048-width":256,"2048x2048-height":238,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","card_image-width":256,"card_image-height":238,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/10\/SubAddressAfterBase.png","wide_image-width":256,"wide_image-height":238}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":" Get a summary of subaddresses<\/strong><\/p>\n With the subaddressSummary<\/a> parameter, users will receive a short description of the apartments at an address.

In the situation where an input address includes an apartment number that cannot be matched by the geocoding service, the PotentialID<\/a> field has been added to further support those efforts. While the service can classify the input as an apartment, the Match ID belongs to the main address.<\/p>\n The PotentialID<\/a> field contains an identifier for the full address with an apartment that represents what the MatchID would be if the apartment had been matched. For example, if an input of 380 New York Street Unit 234 matches to 380 New York Street, this indicates that Unit 234 was not matched. In the output for match narrative, Unit 234 is listed as classified and unmatched because there is no record in the reference data for this address. The Potential ID value can be used to query the service in the future to see if a new record exists.<\/p>\n Building details<\/strong><\/p>\n With the growing need to support descriptive elements of a building, Esri is adding new output fields to support these elements as reference data becomes available.<\/p>\n The RoomType<\/a> field describes the subsection of a unit in a building. For example: \u2018Room\u2019 or \u2018Rm\u2019.<\/p>\n The RoomName<\/a> field contains the name, or number, of a room. For example: \u2018123\u2019 in \u201cRoom 123\u201d.<\/p>\n The WingType<\/a> field describes the classification of a wing in a building. Wings are subaddress elements that represent the subsection of a building.<\/p>\n The WingName<\/a> field contains the name or number of a wing. For example: \u2018South\u2019 in \u201cSouth Wing\u201d.<\/p>\n <\/p>\n Point address improvements<\/strong><\/p>\n The service now provides more accurate matches for locations with house numbers, benefiting additional regions such as Brazil, Canada, Colombia, Hong Kong, Indonesia, <\/span>Puerto Rico, <\/span>USA, US Virgin Islands<\/span><\/p>\n Subaddress support<\/strong><\/p>\n The service now provides full support when searching for subaddresses in Austria.<\/p>\n"},{"acf_fc_layout":"content","content":" <\/p>\n Ready to explore the enhanced capabilities of the ArcGIS Geocoding Service?
