New Data in Address Layer 2

Address Layer 2 contains a range of new data, such as:

  • Alternative geographic addresses: for example, 12 Old Town, London, SW4 0JY is also available as 12 Old Town, Clapham, London, SW4 0JY. This is provided in BS7666 part 3 format.
  • Building name aliases: buildings that may be known by a name as well as a house number. For example, Railway Cottage may also be known as 61 Station Road.
  • Welsh alternatives - for example, 13 Mill Street, Aberystwyth, SY23 1HZ could also be 13 Dan Dre, Aberystwyth, SY23 1HZ.
  • Classifications: each address is classified as either residential or commercial. These are then further analysed where the trading name provides further details, for example, Barclays Bank - bank, and W H Smith - retail.  The detailed classifications are sourced from Ordnance Survey, Valuation Office Agency and the National Land Use Database descriptions.
  • Objects without postal addresses (OWPAs): over 1 million buildings and other features that do not have a postal address, such as churches, community centres, depots, masts and so on. These have all been classified as covered above, and given a geographic address; for example, Community Hall, Hulse Road, Southampton, SO15 2JW.
  • Multi-occupation without postal addresses (MOWPAs): details of individual households that currently do not have mail delivered to their own letter box, such as flats; for example, 'Flat A, Flat B' at 1 London Road, Maidstone, Kent, ME16 8QL. These are all supplied complete with the parent delivery address. The first release will contain 150 000 structured addresses, and this will grow during subsequent data updates. These are supplemented by a total of over 400 000  'multi-occupation' counts, which are included within the address theme. These cover buildings where multi-occupation occurs, such as halls of residence, old peoples' home, but the internal details are not known such as flats.
  • Integration with other OS MasterMap layers: the address TOID is linked to the Topographic and Integrated Transport NetworkTM (ITN) TOIDs.
  • Cross reference to external datasets: this currently includes Royal Mail's Unique Delivery Point Reference Number (UDPRN) and Unique Multi-Residence Reference Number (UMRRN) and the Valuation Office Agency's Unique Address Reference Number (UARN).
