AddressBase products

The AddressBase® product family combines the best elements of addressing products from three leading address data providers - Local government, Ordnance Survey and the Royal Mail.

Coverage

  • Small scale - national

Data use

  • Addressing

Data format

  • Vector

AddressBase takes the most valuable elements from local government’s National Land and Property Gazetteer (NLPG), Ordnance Survey’s OS MasterMap Address Layer 2, the Royal Mail Postcode Address File (PAF), and The Valuation Office Agency.

We make this available to customers in the following three products:

Each AddressBase product has been designed to meet specific market needs, however the following key features are consistent across all three products. These are as follows:

  • the Unique Property Reference Number (UPRN) - allowing you to cross reference data easily
  • geospatial coordinates - allowing you to understand the location of an address in a geographic context
  • the Royal Mail Postal Address File (PAF) with corresponding unique identifier (UDPRN) - allowing you to determine the use of an address (residential or commercial)

Who brings this data together?

This data is brought together by GeoPlace, a joint venture between Ordnance Survey and the Local Government Association, within the National Address Gazetteer infrastructure.

How can this help my organisation?

For commercial organisations AddressBase provides the link between postal addresses and the UPRN as a means to locate and uniquely reference customers and assets to enable business growth, gain competitive advantage and reduce operational costs. For Government organisations the UPRN is an underpinning linking mechanism that removes error in data exchange and communication, supports citizen service improvement and delivers efficiency gains in operational processes.

Our AddressBase partners

GeoPlace

GeoPlace is a public sector limited liability partnership between the Local Government Association (LGA) and Ordnance Survey.

Local Government Association

The Local Government Association (LGA) is here to support, promote and improve local government.

AddressBase

AddressBase contains Royal Mail PAF addresses, both commercial and residential where they have been matched to the local authority Unique Property Reference Number (UPRN).

This allows you to link additional information about a property to a single address and locate it on a map.

The additional data contained within AddressBase over standard PAF include spatial coordinates, unique property reference numbers and primary function classifications.

AddressBase Plus

AddressBase Plus merges two address datasets together (PAF and Local Authority) to provide the best available view of addresses currently defined by Local Authorities.

Current Local Authority addresses that have not been matched to PAF add more addresses to those already contained within AddressBase.

Each address has spatial coordinates, a classification, cross-references and a UPRN.

AddressBase Premium

AddressBase Premium provides the most detailed view of an address throughout its lifecycle.

It builds upon the PAF and Local Authority current address data contained within AddressBase Plus, and includes address or property data captured at various stages of the address lifecycle, including initial creation, minor changes and history.

Each address has spatial coordinates, a classification, cross-references and a Unique Property Reference Number.
