Location

5.3.14.1

A location is described as a TOWN_NAME or as a combination of TOWN_NAME and LOCALITY.  LOCALITY should only be used if it is necessary to distinguish between two Streets of the same name within the same town.  Acceptable exceptions to this rule are identified in Section 5.3.14.8.

5.3.14.2

Punctuation must only be included within the TOWN_NAME and LOCALITY if the punctuation is part of the official TOWN_NAME and LOCALITY, for example “Stoke-on-Trent”.  Ampersands must be replaced with the word “and”.  Full stops or commas must not be used as part of any TOWN_NAME and LOCALITY.

5.3.14.3

The Attribute name TOWN_NAME can be misleading particularly in sparsely populated areas.  It must be populated with one of the following geographical identifiers, where continuity of the TOWN_NAME can be achieved for the Street Name or Street Description:

  • The name of a city.
  • The name of a town.
  • The name of a village.
  • The name of a hamlet.
  • The name of a parish.
  • The name of a recognised settlement.
  • A geographical identifier.

5.3.14.4

If the TOWN_NAME is the same as the post town created by Royal Mail and POSTTOWN is used to create Postal Addresses, then one of the two Fields must be suppressed either for the application user or when Postal Address lists are created.  For more information on how to create a Postal Address list, see Section 13.

5.3.14.5

The TOWN_NAME therefore represents one of the above and not the post town allocated by Royal Mail, although they are often the same name. 

5.3.14.6

A TOWN_NAME must always be entered for type 1 and type 2 Streets and may be entered for type 3, 4 and 9 Streets.

5.3.14.7

A LOCALITY defines an area or geographical identifier within a town, village or hamlet that must be a recognised geographical name.  

5.3.14.8

LOCALITY must only be used for Street Records in the following scenarios:

  • If there is more than one Street of the same name in the same town.
  • If the inclusion of a locality is necessary in addition to TOWN_NAME to avoid ambiguity in the identification of that Street and there is evidence of a recognised geographical identifier.
  • If a settlement, with its own settlement name in common use, is in the same parish as another settlement but is distinctly separate, particularly in sparsely populated areas.
  • If a site contains named Streets and the site name is included in the Postal Address, for example airports, out of town shopping centres, industrial estates.  This allows for Postal Addresses to be constructed which are meaningful to users.
  • If the Street falls within a London Borough the following rules apply.  For a map of the London Boroughs, see Appendix H:

 

  • For all Streets within Inner London Boroughs the town name must be recorded as ‘London’ and an appropriate locality must be added to each Street. This applies to:
    • Camden.
    • City of London.
    • City of Westminster.
    • Hackney.
    • Hammersmith & Fulham.
    • Haringey.
    • Islington.
    • Kensington & Chelsea.
    • Lambeth.
    • Lewisham.
    • Southwark.
    • Tower Hamlets.
    • Wandsworth.

 

  • For all Streets within Outer London Boroughs the appropriate local description for the town should be used, for example Wimbledon, Enfield, Harrow etc. and the locality only used to avoid ambiguity within that ‘town’.  London Boroughs must reach agreement as to how this Field is populated consistently across Boroughs to avoid duplication.  This applies to:
    • Barking and Dagenham.
    • Barnet.
    • Bexley.
    • Brent.
    • Bromley.
    • Croydon.
    • Ealing.
    • Enfield.
    • Greenwich.
    • Harrow.
    • Havering.
    • Hillingdon.
    • Hounslow.
    • Kingston upon Thames.
    • Merton.
    • Newham.
    • Redbridge.
    • Richmond upon Thames.
    • Sutton.
    • Waltham Forest.

 

  • The following rules must be applied when creating localities:
    • If LOCALITY is used it should be a meaningful geographic identifier.
    • LOCALITY should be a local area name.
    • If LOCALITY and TOWN_NAME are the same, then only the town name should be recorded.
    • Post towns or postcodes or parts of postcodes must not be entered in LOCALITY.
    • Street names should not be entered in LOCALITY.
    • The LOCALITY must be agreed between the Authority Street Custodian and the Authority Address Custodian.
       

5.3.14.9

The LOCALITY AND TOWN_NAME contained in the ASG must not be based on Postal Address locations and post towns as defined by the Royal Mail Address Management Unit (AMU).  They are geographical identifiers which help identify a BLPU and an LPI through the commonly known description of the location.

5.3.14.10

If Streets pass through a number of different identified geographic locations, each Street section, to avoid ambiguity, must be recorded as a separate Street Record with the appropriate geographic location. 

5.3.14.11

If there are no properties associated with Streets passing through a number of different locations that are recorded as single Street Records, these shall not be split until a change is required.  Splits to such Streets shall occur at clearly marked boundaries or landmarks to facilitate identification of different Street start and end points on the ground.  

5.3.14.12

Type 1 Streets and type 2 Streets must be split only if one of the following changes occurs along the length of the Street:

  • The SNN Authority.
  • The LOCALITY Field if it is used to identify a local geographic boundary.
  • The Street Name.
  • The town name or locality name.

5.3.14.13

Type 1 Streets must not be split to show change of maintenance responsibility. 

5.3.14.14

Type 2 Streets must be split only at a recognisable physical marker.
