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 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.

1,572,685 polygon records with EASTING,NORTHING and PAREA (postcode area) fields. Individual polygons could be aggregated using PAREA field and entire coverage clipped to a coastline dataset to give a GB Postcode Area dataset. Dataset created by reducing all records in Code-Point Open to a unique point set based on Easting & Northing, allocating the most frequently occurring postcode area at each unique location by sub-stringing unit postcode labels and then creating a thiessen polygon coverage from the pointset in arcinfo workstation. GIS vector data. This dataset was first accessioned in the EDINA ShareGeo Open repository on 2010-09-13 and migrated to Edinburgh DataShare on 2017-02-21.

The Locality and Postcode Areas dataset depicts the authoritative boundaries and names of localities. A locality is an administrative area which uniquely defines the name of a place to enable street addressing. In metropolitan areas it may also be referred to as a âsuburbâ. Every locality has been defined with boundaries that do not overlap with other localities. Because of its unique name and unambiguous boundaries, a locality provides the official reference point for addressing purposes. A locality may include a town having the same name Locality Boundaries generally extend to High Water Mark and may not include uninhabitable offshore rocks and small islands. Larger named islands which are not included in this dataset will, if required for addressing or location purposes, use the official island feature name as the locality. Attributes include: The approved locality name (NAME); The Postal Code assigned by Australia Post for a locality (POSTCODE); The plan reference of the Central Plans Office plan that defined the initial locality (PLAN_REF); The Gazettal date for the proclamation first proclaiming the locality (GAZ_DATE) The Place Names Advisory Panel (formally Nomenclature Board of Tasmania) approves the Locality boundaries and names, and Postcodes have been assigned by Australia Post.

A lookup between 2011 Census enumeration postcodes for England and Wales, and the parishes / communities, wards and local authority districts as at 31 December 2011. Enumeration postcodes are a sub-Output Area (OA) geography used only for the publication of estimates of males, females and households in the 2011 Census. The enumeration postcodes are defined as only those valid unit postcodes that were recorded during the 2011 Census as containing usually resident population. Postcodes have been assigned using a ‘point-in-polygon’ methodology that plots each postcode's mean address (centroid) into the areas of each of the parishes / communities, wards and local authority districts (LAD). In England there is not a full coverage of parishes, so the 2011 Census enumeration postcodes that do not fall into a parish will have no parish allocation. There are also 23 parishes (0.2%) that do not contain any enumeration postcode centroids. This occurs where a parish contains population, but the centroid of the postcode falls outside the parish. In these instances it is not possible to allocate a postcode to the parish.

A list of central and local government land in England, which may not be registered with HM Land Registry (HMLR).

HMLR has created this dataset for the Ministry for Housing, Communities and Local Government (MHCLG) by combining HMLR freehold polygon data with the public sector ownership data currently openly available from the Office of Government Property.

The dataset is not definitive or complete as not all central and local government data is captured, and/or available, and the two datasets are not held in the same format. The list is therefore indicative rather than definitive.
