Postcode Districts Grid References - Scotland

Alternative title(s)

Abstract

Postcode district grid references are created and maintained by National Records of Scotland (NRS). Grid references are calculated based on the Royal Mail Delivery Point Count of the postcodes within the postcode district, while ensuring that the centroid is located inside the boundary. NRS publish these grid references twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.

Lineage

National Records of Scotland (NRS) delineate notional boundaries around address content of live small user postcodes utilising real world features depicted in Ordnance Survey’s MasterMap® product. Postcodes that fall within the same district are dissolved to create postcode district boundaries. Grid references are calculated in ESRI desktop GIS tools, ensuring that the centroid is located inside the polygon. As postcode boundaries are subject to continuous change, the district grid references may change as the postcode geographies are altered. This dataset is formally issued twice a year as part of National Records of Scotland’s Scottish Postcode Directory (SPD). In addition to postcode geographies, the SPD contains a database detailing the higher geographies that each postcode is assigned to. NRS produce two versions of the SPD, one containing Royal Mail Delivery Point information and another without. If you require delivery point information please contact customer services. For more information on the postcode geography please see background note at https://www.nrscotland.gov.uk/files/geography/Products/postcode-bkgrd-info.pdf or contact NRS Geography.
