Postcode unit boundaries are created and maintained by National Records of Scotland (NRS) for every live small user postcode so that the entire land surface of Scotland is covered by postcode polygons.
The dataset represents the smallest plotted unit in Scotland which supports the production of high quality statistics.
NRS publish these boundaries twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.
Note the published version of the SPD does not include Royal Mail information on Delivery Point Count (DPC), Delivery Point Count Non-Residential (DPCNR) or Household Count (HC). Those interested in this information should enquire with geographycustomerservices@nrscotland.gov.uk.
