AddressBase Plus | Data Products | Ordnance SurveyOrdnance Survey

AddressBase Plus contains current properties using addresses sourced from Local Authorities, Ordnance Survey and Royal Mail for England, Wales and Scotland. The product currently contains approximately 37 million records.

The product contains all current addresses validated from Local Custodians and non-postal addresses such as ponds, electricity sub-stations and telephone boxes are also included.

The product enables the end-user to locate an address or property on a map using either X, Y coordinates supplied on a British National Grid or Latitude and Longitude coordinates provided on an ETRS89 projection, and display the Local Authority address elements or the Royal Mail address elements where matched.

Features

Flat file model

AddressBase Plus is structured in a flat file model - containing current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail matched to the UPRN.

Accuracy guaranteed

The address information is sourced from 380 local authorities across Great Britain, our own large-scale mapping, Royal Mail and the Valuation Office Agency.

Useful addresses

As well as 28 million defined properties, Ordnance Survey have included more than seven million local authority addresses, such as depots and church halls, places of worship and community centres.

Property classification

Understanding the need to categorise properties, Ordnance Survey incorporated a four-level classification scheme that explains the function of each property.

Use cases

Individual address referencing for direct marketing teams

Take your data analysis to the next level by referencing data to individual addresses (such as flats) rather than mail delivery points (houses divided into flats).

Additional information

Advantage of AddressBase Plus over AddressBase

AddressBase contains Royal Mail PAF addresses and assigns an x and y coordinate to every address. This lets you carry out only relatively basic analysis.

AddressBase Plus also includes current properties and addresses sourced from local authorities, Ordnance Survey and Royal Mail. Records are matched to the UPRN and structured in a flat-file model.

AddressBase Plus holds more records than AddressBase as it includes objects without postal addresses, such as subdivided properties, places of worship and community centres. It also allows the end-user to locate an address or property on a map, through the assigned x and y coordinates.

Crucially, cross-referencing the information with OS MasterMap products via the OS MasterMap Topography Layer and Integrated Transport Network (ITN) Layer Topographic Identifiers (TOIDs) lets you view address data within a wider geographic context.

Properties yet to be built

Properties yet to be built do not appear in AddressBase Plus. You'd need AddressBase Premium for this information. It's ideal when you're planning the future provision of infrastructure services such as sewerage or high-speed broadband.

Data from Royal Mail’s PAF

The database is a vital component of the single address gazetteer database and is in each of the AddressBase products where there has been a match confirming the address to the LLPG address.
