National Address DatabaseThis National Geospatial Data Asset (NGDA) dataset, shared as a U.S. Department of Transportation (USDOT) feature layer, displays address data in the United States. Per USDOT, "The U.S. Department of Transportation (USDOT) and its partners from all levels of government recognize the need for a National Address Database (NAD). Accurate and up-to-date addresses are critical to transportation safety and are a vital part of Next Generation 9-1-1. They are also essential for a broad range of government services, including mail delivery, permitting, and school siting. To meet this need, USDOT partners with address programs from state, local, and tribal governments to compile their authoritative data into the NAD."District of Columbia (DC) Residential AddressesData currency: Current federal service (Address Points from National Address Database)NGDAID: 196 (National Address Database (NAD))For more information: Getting to know the National Address Database (NAD); National Address DatabaseFor feedback, please contact: Esri_US_Federal_Data@esri.comNGDA Data SetThis data set is part of the NGDA Transportation Theme Community.

The National Address Database is one of the nine databases of the public reference data service. It is the only address database officially recognized by the administration.

Digital service for shared use and basic infrastructure on which many public policies are based, it is part of the information system and communication of the State and is as such placed under the responsibility of the Prime Minister.

Its management is ensured by the Interministerial Directorate of Digital (DINUM), which is responsible for define the terms of governance and operation (following a decision by the Prime Minister).

Its construction is ensured thanks to many partners, and in the first place by the municipalities , the only competent authorities in terms of addressing.

Geoscape G-NAF is the geocoded address database for Australian businesses and governments. It’s the trusted source of geocoded address data for Australia with over 50 million contributed addresses distilled into 15.4 million G-NAF addresses. It is built and maintained by Geoscape Australia using independently examined and validated government data.

From 22 August 2022, Geoscape Australia is making G-NAF available in an additional simplified table format. G-NAF Core makes accessing geocoded addresses easier by utilising less technical effort.

G-NAF Core will be updated on a quarterly basis along with G-NAF.

Further information about contributors to G-NAF is available here.

With more than 15 million Australian physical address record, G-NAF is one of the most ubiquitous and powerful spatial datasets. The records include geocodes, which are latitude and longitude map coordinates. G-NAF does not contain personal information or details relating to individuals.

Updated versions of G-NAF are published on a quarterly basis. Previous versions are available here

Users have the option to download datasets with feature coordinates referencing either GDA94 or GDA2020 datums.

Changes in the February 2025 release

• Nationally, the February 2025 update of G-NAF shows an overall increase of 47,284 addresses (0.30%). The total number of addresses in G-NAF now stands at 15,706,733 of which 14,867,032 or 94.65% are principal.

• In the February 2025 release of G-NAF, over 300 addresses in Morra, Western Australia have been updated. About 150 addresses have changed locations and 160 properties now have street numbers instead of lot numbers. Some properties are still using lot-numbers, resulting in two addressees. This issue will be resolved in the May 2025 update of G-NAF.

• In the February release, Geoscape has re-classified geocode types of ‘Property Access Point Setback’ (PAPS) to be ‘Property Access Point’ (PAP) in South Australia where the geocode falls within a road casement as the geocode is not set back into a land parcel. This update has changed approximately 57,000 geocodes to PAP from their previous classification of PAPS, while there are some 14,000 PAPS geocodes that remain unchanged.

• Geoscape has moved product descriptions, guides and reports online to https://docs.geoscape.com.au.

Further information on G-NAF, including FAQs on the data, is available here or through Geoscape Australia’s network of partners. They provide a range of commercial products based on G-NAF, including software solutions, consultancy and support.

Additional information: On 1 October 2020, PSMA Australia Limited began trading as Geoscape Australia.

Connecticut address point dataset used for locating 9-1-1 calls. The address point feature class format is derived from National Emergency Number Association (NENA) and Federal Geographic Data Committee (FGDC) addressing standards. All address components, like address number, streets name and unit number, are broken up into their individual components to enable maximum flexibility for use. Fields within feature class should be able to accommodate all addresses within the state of Connecticut. The source for the addresses is primarily derived from municipal parcel data and other municipal sources.

Address Analysis

Addressing analysis is there to help regional leaders and national actors identify the most “lagging” municipalities in terms of addressing. These are estimates based on the dataset of Number of addressable premises per commune. This approximation is only relevant for small, predominantly residential and pavilion municipalities.

Please note: We have a known issue, where 'unit_value' is not represented in the address_component_value field for a number of address records in the AIMS: Address Component table. Where it is not populated, it will present as duplicated addresses. LINZ is working to resolve this issue. Sorry for any inconvenience this may cause. Please read: The AIMS: Address Component data table is part of the set of comprehensive AIMS Address tables. The Address Component table contains core information relating to a street address such as Street Number or Road Name and is stored in the address_component_value field of the Address Component table. The address_component_type describes the type of component e.g. Address number, road name, town/city. This table also includes component order and group to allow for address number elements and road name elements to be grouped together. This layer contains information advised to LINZ by Territorial Authorities (TAs). Under the Local Government Act 1974 (section 319) it is the responsibility of the TAs to advise LINZ (the Surveyor General) of all allocated addresses in their district. The comprehensive address dataset includes eight data tables and nine lookup tables. The dataset has been sourced from LINZ’s Address Information Management System (AIMS), a centralised database for the management of national addresses, including for electoral purposes. This set of normalised tables replaces the single Landonline: Street Address layer currently published on LDS. For a simplified version of the data contained within these tables see NZ Street Address. Please refer to the Street Address Data Dictionary for detailed metadata and information about this layer.

The Reach Address Database (RAD) stores the reach address of each Water Program feature that has been linked to the underlying surface water features (streams, lakes, etc) in the National Hydrology Database (NHD). (A reach is the portion of a stream between two points of confluence. A confluence is the location where two or more streams flow together.)

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The Address Ranges Feature Shapefile (ADDRFEAT.dbf) contains the geospatial edge geometry and attributes of all unsuppressed address ranges for a county or county equivalent area. The term "address range" refers to the collection of all possible structure numbers from the first structure number to the last structure number and all numbers of a specified parity in between along an edge side relative to the direction in which the edge is coded. Single-address address ranges have been suppressed to maintain the confidentiality of the addresses they describe. Multiple coincident address range feature edge records are represented in the shapefile if more than one left or right address ranges are associated to the edge. The ADDRFEAT shapefile contains a record for each address range to street name combination. Address range associated to more than one street name are also represented by multiple coincident address range feature edge records. Note that the ADDRFEAT shapefile includes all unsuppressed address ranges compared to the All Lines Shapefile (EDGES.shp) which only includes the most inclusive address range associated with each side of a street edge. The TIGER/Line shapefile contain potential address ranges, not individual addresses. The address ranges in the TIGER/Line Files are potential ranges that include the full range of possible structure numbers even though the actual structures may not exist.

This dataset is an enrichment of the INSEE dataset (SIRENE database of enterprises and their establishments (SIREN, SIRET)) (https://www.data.gouv.fr/en/datasets/base-sirene-des-entreprises-et-de-leurs-etablissements-siren-siret/). This enriches the original base as follows: - Breakdown of the StockEstablishment file by geographical grid: departments and municipalities. Addition of a number of columns relating to the geolocation of establishments based on the most relevant proximity score between the address indicated in the SIRENE database and the National Address Database or the Points of Interest of Openstreetmap. Longitude field: longitude of the establishment Field "latitude": Latitude of establishment Field geo_score: Trust score returned by the addok geocoder (between 0 and 1, the higher the score, the more relevant the geocoding seems) Field geo_type: type of address found Field geo_address: wording of the address found Field geo_id: identifier of this address in the source database where it was found (BAN or POI) Field geo_line: which address line of the SIRENE database could be geocoded (G=geographical, D=declared, N=normalized) Field geo_l4: line 4 to standard AFNOR address Field geo_l5: line 5 to standard AFNOR address The processing allowing the production of this dataset is carried out by Etalab. It is largely inspired by the previous work of Christian Quest available here. This processing is based on the geocoder Addok. This dataset is used in the search engine of the business directory and in its API (https://api.gouv.fr/les-api/api-recherche-entreprises).

Please note this dataset is an archived version of the Geocoded National Address File (G-NAF). For the latest version of the G-NAF please go to this url: https://data.gov.au/dataset/ds-dga-19432f89-dc3a-4ef3-b943-5326ef1dbecc/details?q=gnaf

An edge can have several feature names; an address range located on an edge can be associated with one or any combination of the available feature names (an address range can be linked to multiple feature names). The address range is identified by the address range identifier (ARID) attribute that can be used to link to the Address Ranges Relationship File (ADDR.dbf). The linear feature name is identified by the linear feature identifier (LINEARID) attribute that can be used to link to the Feature Names Relationship File (FEATNAMES.dbf).

The National Address Database (BAN) is the reference database of addresses officially recognised by the Administration. The completeness of this base allows services to be delivered in the right place. This national base is built by adding the Local Address Bases (LABs) produced by the municipalities. The BAL of the City of Marseille is structured in accordance with the national model of the BAN. It contains all the postal addresses of the municipality. It is organized by arrondissement (one file per arrondissement)

The AIMS: Address Position data table contains the point location of an address and is part of the AIMS: Street Address.
