The Unique Property Reference Number (UPRN) is the unique identifier for every addressable location in the UK.

Unique Property Reference Numbers (UPRNs) and Unique Street Reference Numbers (USRNs) are now openly available and royalty-free for use on Open Government Licence (OGL) terms from Ordnance Survey.

Unique Property Reference Number (UPRN) – simple but powerful 

The Unique Property Reference Number (UPRN) is the unique identifier for every addressable location across the UK.

An addressable location may be any kind of building, or it may be an object that might not have a ‘normal' address – such as a bus shelter or an electricity substation for example. UPRNs provide every property (or object) with a consistent identifier throughout its lifecycle, from planning through to demolition.

Who allocates Unique Property Reference Number (UPRN)?

UPRNs are allocated by local authorities and by Ordnance Survey (OS) from a range provided by GeoPlace.  Local authorities have statutory permission to name and number every street and property in Great Britain and also allocate UPRNs to other objects. OS identifies features in the landscape that might not have a ‘normal' address and includes them in its AddressBase products.

A central source for addresses and streets

GeoPlace is the central source for UK addresses and streets. We work contractually with all 339 councils in England and Wales which have statutory responsibility for approving and creating addresses and 174 local highways authorities. 

We manage a central hub of 42.8 million addresses and 1.3 million streets, taking feeds of address and street data from local authorities in England and Wales, central government, Ordnance Survey, Royal Mail and data from Scotland, Northern Ireland, Isle of Man and the Channel Islands via the Improvement Service, Land & Property Services, Isle of Man Government and Digimap respectively.

Data from Northern Ireland is via Pointer, the address database for Northern Ireland. Land & Property Services (LPS) maintains the database with help from local councils and Royal Mail.

Why do we need Unique Property Reference Numbers (UPRN)?

Unique and authoritative, the UPRN is like a National Insurance number for physical objects. Everything in Great Britain can be identified with a UPRN.

This authoritative ‘code' can be used to create trusted connections between disparate sources of information sharing a common characteristic: location. Even if there are other issues with the datasets, the UPRN is a simple and unique reference point.

Crucially, when organisations add the UPRN to any kind of data, they can link matching records in different databases together. This means fewer errors in data exchange and communication, but far greater efficiency in all kinds of operations.

Many technologies can be used to share the UPRN, including spreadsheets, databases, XML/GML schema and linked data. Groups already using the UPRN include local and central government bodies, the emergency services, insurance providers, and utility companies.

How is the Unique Property Reference Number (UPRN) evolving?

Under the Public Sector Mapping Agreement, every organisation in the public sector can use UPRNs on a royalty-free and open basis.

For example, the data is being used for emergency response by the emergency services; by HM Revenue and Customs to collect taxes; by Department of Work and Pensions to pay benefits, and by the Environment Agency to produce flood plans.

This means immense savings are possible – money, time, resources, and lives.

The entire public sector has access to the address information created and maintained by local authorities through the AddressBase® range of products and made available by Ordnance Survey. 

On the 2nd of April 2020, the Government announced that the Unique Property Reference Number (UPRN) and Unique Street Reference Number (USRN) will be released under Open Government Licence. Additionally, the Open Standards Board, via Government Digital Service (GDS), has mandated that from 1st July 2020, the UPRN and USRN are the public sector standard for referencing and sharing property and street information.

How do I get hold of Unique Property Reference Numbers (UPRNs)?

UPRNs are available to the market as part of OS AddressBase®, a portfolio of data products that’s been jointly created by GeoPlace and Ordnance Survey (OS).

As the national mapping service, OS is responsible for providing, promoting, marketing and licensing AddressBase®. The AddressBase® portfolio comprises a family of related but distinct products.

AddressBase® Premium is the flagship addressing product. It provides:

  • a UPRN for every addressable location
  • every authoritative local authority geospatial address
  • Royal Mail postcodes and post town names (where matched to a UPRN)
  • addresses with sub-divisions or multiple occupants
  • objects without postal addresses such as bus shelters or named ponds
  • cross-references to VOA data and OS MasterMap® Topography and Highways Network
  • street identifiers (Unique Street Reference Numbers (USRNs)
  • coordinates
  • classification for each address

A new AddressBase® product, AddressBase® Core, was added to OS’s addressing portfolio in July 2020. It is simplified, easy to use data product providing all ‘live’ addresses with a weekly update frequency. It offers a single line address and simplified attribute structure, with cross-references to PAF and OS MasterMap®. Classification of addresses is provided at both a primary and secondary level.
