Postcode district boundaries are created and maintained by National Records of Scotland (NRS). Postcode districts are represented by the outward code (first part of a postcode). For example, if the individual postcode is EH12 7TB, then the district of that postcode is EH12. Postcodes that fall within the same district are dissolved to create postcode district boundaries. 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.

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.

Postcode sector boundaries are created and maintained by National Records of Scotland (NRS). Postcode districts are represented by the outward code (first part of a postcode) plus the first character of the inward code. For example, if the individual postcode is EH12 7TB, then the sector of that postcode is EH12 7. Postcodes that fall within the same sector are dissolved to create postcode sector boundaries. 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.

This is the ONS Postcode Directory (ONSPD) for the United Kingdom as at February 2024 in Comma Separated Variable (CSV) and ASCII text (TXT) formats. This file contains the multi CSVs so that postcode areas can be opened in MS Excel. To download the zip file click the Download button. The ONSPD relates both current and terminated postcodes in the United Kingdom to a range of current statutory administrative, electoral, health and other area geographies. It also links postcodes to pre-2002 health areas, 1991 Census enumeration districts for England and Wales, 2001 Census Output Areas (OA) and Super Output Areas (SOA) for England and Wales, 2001 Census OAs and SOAs for Northern Ireland and 2001 Census OAs and Data Zones (DZ) for Scotland. It now contains 2021 Census OAs and SOAs for England, Wales and Northern Ireland. It helps support the production of area-based statistics from postcoded data. The ONSPD is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The ONSPD is issued quarterly.

While Royal Mail (RM) allocate and maintain postcodes for the purposes of delivering mail, National Records of Scotland (NRS) create and maintain digital postcode geographies to support the production of high quality statistics. This dataset provides the boundaries for each live postcode (e.g. KY7 6DG) in Scotland. 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. The SPD also details a range of higher geographies to which each postcode is assigned.

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.

Postcode grid references are created and maintained by National Records of Scotland (NRS) for every live small user postcode to accompany the postcode unit boundaries. Postcode grid references are used in point in polygon processes to allocate each postcode to a set of higher area geographies (e.g. Health Boards). Grid references are published twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.

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.

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. This is the set of postcode boundaries used for 2011 census outputs. The dataset contains 145,690 postcode polygons.

This dataset is published as Open Data.2022 Census Settlement:The 2022 Census Settlement boundaries have been created using the Census 2022 frozen Postcode boundaries.National Records of Scotland (NRS) create Settlement boundaries by categorising Postcodes as either high or low density. A Postcode was defined as high density if at least one of the following applied:It had more than 2.1 households per hectare.It had more than 0.1 non-residential addresses per hectare; orThe Census population per hectare exceeds five people.The threshold densities were set as they were found to give a good approximation to the built-up areas identified in previous Censuses using traditional methods. The second condition was included such that non-residential parts (e.g. industrial estates) of built-up areas could be identified and included.An additional rule was implemented from the 2016 (non-Census) version, which stated that any Postcodes which fell within the previous version Settlement boundary(based on centroid point in polygon assignment) would automatically be included in the new Settlement.The classified Postcodes were then grouped into areas of neighbouring high-density Postcodes, or ‘Settlements’. Areas of low-density Postcodes completely surrounded by the high-density areas (i.e. ‘holes’) were incorporated into the Settlement.Populations for each area were then calculated, and any settlement with fewer than 500 residents was discarded.2022 Census Settlement and Locality CentroidsEach population weighted centroid was calculated using a median centroid algorithm, the result of which is less influenced by outliers than the result of an algorithm to calculate the mean centroid. The process for creating Census 2022 Settlements centroids was automated usingESRI ArcGIS, but the general method is as follows. The median easting and northing coordinate pair for all Census 2022 frozenPostcodes within the Settlement is calculated, giving a notional centroid of the Settlement. The distance from each of the Postcode centroids to the notional (or median) centroid is calculated using Pythagoras' Theorem. The Postcode coordinate pair with the shortest distance to the median was then chosen to represent the centroid of the Settlement/Locality.

Les limites des districts du code postal sont créées et maintenues par National Records of Scotland (NRS). Les districts de code postal sont représentés par le code sortant (première partie d’un code postal). Par exemple, si le code postal individuel est EH12 7 TB, alors le district de ce code postal est EH12. Les codes postaux qui entrent dans le même district sont dissous pour créer des limites de district de code postal.

NRS publie ces limites deux fois par an dans le cadre du Scottish Postcode Directory (SPD) qui devrait être considéré comme la source définitive des géographies du code postal en Écosse.

This file contains the 'Full' NHS Postcode Directory (NHSPD) as at November 2022.

I riferimenti alla griglia di distretto del codice postale sono creati e mantenuti da National Records of Scotland (NRS). I riferimenti alla griglia sono calcolati in base al Royal Mail Delivery Point Count dei codici postali all'interno del distretto di codice postale, assicurando al contempo che il centroide si trovi all'interno del confine.

NRS pubblica questi riferimenti alla griglia due volte l'anno come parte dello Scottish Postcode Directory (SPD) che dovrebbe essere considerato la fonte definitiva per le geografie dei codici postali in Scozia.
