A lookup between postcodes and postcode sectors, postcode districts and postcode areas as at March 2021 in England and Wales (File size 5MB).

Open Postcode Geo is a postcode dataset and API optimised for geocoding applications. You can use Open Postcode Geo to geocode a dataset, geocode user input, and therefore build a proximity search.

Data is derived from the ONS (Office for National Statistics) postcode database and is free to use, subject to including attributions to ONS, OS (Ordinance Survey) and Royal Mail.

Information is also provided on a range of topics, including education, health, crime, business, etc.

Postcodes can be entered at area, district, sector, and unit level - see Postcode map for the geographical relationship between these.

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.

The PTV Postcode Boundaries Germany data set is based on information from a wide range of sources and, in addition to the postcode boundaries (5-digit postcodes), also contains the postcode regions (2-digit postcodes) and postcode zones (1-digit postcodes) as well as the postcode districts (PLB, 4-digit).

Metropolitan postcode regions have been produced in the EU together with the cities of Helsinki, Espoo and Vantaa. The documentation contains detailed territorial boundaries and information on postal codes and places of business.

The boundaries of postal codes have been produced largely on the basis of the municipalities’ own boundaries and are therefore compatible with the municipalities’ own postal code area boundaries. The accuracy of the harmonised material varies slightly from one municipality to another, due to baseline data and maintenance practices. The postcode areas are not linked to the administrative divisions and are therefore located in several municipalities. The file contains information on postal codes and post offices. In addition, the indicative names of the regions have been added to the file from Statistics Finland’s open postal code domain material.

For 2019, there will also be material cut along the coastline. This is better suited to visualisations that do not want to include marine areas. The cut has been carried out with the marine material of the Seutu map.

The materials have been completed in the first half of each year.

This product is prepared in conjunction with Australia Post. This is a small dataset which provides an easy to use and affordable entry to the use of postcodes with desktop computer mapping. This file can be used to display the approximate shape of postcode area and the relationships between postcode areas. Scale is 1:10 000 in urban areas, and 1:25 000 to 1:1m in rural areas.

This is the ONS Postcode Directory (ONSPD) for the United Kingdom as at February 2023 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 and Wales. 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. (File size - 234 MB)NOTE: The 2022 ONSPDs included an incorrect update of the ITL field with two LA changes in Northamptonshire. This error has been corrected from the February 2023 ONSPD.NOTE: There was an issue with the originally published file where some change orders yet to be included in OS Boundary-LineÔ (including The Cumbria (Structural Changes) Order 2022, The North Yorkshire (Structural Changes) Order 2022 and The Somerset (Structural Changes) Order 2022) were mistakenly implemented for terminated postcodes. Version 2 corrects this, so that ward codes E05014171–E05014393 are not yet included. Please note that this product contains Royal Mail, Gridlink, LPS (Northern Ireland), Ordnance Survey and ONS Intellectual Property Rights.

This layer is part of Vicmap Lite and contains polygon features delineating postcode areas. Vicmap Lite datasets are suited for use between scales of 1: 250,000 and 1 : 5 million. The polygons were sourced from Vicmap Admin. The level of attribute information and the number of vertices has been simplified to suit the 1: 250,000 - 1 : 5 million scale range. The concept of a Scale Use Code has been introduced to help control the level of detail displayed.

Local climate zones have been developed in the climatology field to characterize the landscape surrounding climate monitoring stations, toward adjusting for local landscape influences on measured temperature trends. For example, a station surrounded by tall buildings may be influenced by the urban heat island effect compared to a station in an agricultural area. The local climate zone classification system was developed by Iain Stewart and Tim Oke at the University of British Columbia. The classification scheme has been adopted by the World Urban Database Access and Tools Portal (WUDAPT) project, which aims to produce local climate zone maps for the entire world at a scale of ~ 100m. Local climate zones take building and vegetation type and height into account, and therefore serve as indicators of urban form, from dense urban (high building with little vegetation) to industrial/commercial (large lowrise buildings with paved areas) and natural (dense trees, low plants, water). How local climate zones are related to human health is a new area of research.CANUE staff and students worked in collaboratation with WUDAPT researchers to map local climate zones for Canada, using scripts developed in Google Earth Engine and applied to LandSat imagery for key time periods. Each postal code has been assigned to one of 14 local climate zone classes. In adition, seven groups have been created by aggregating similar local climate zones, and the percentage of group in the neighbourhood (1km2) around each postal code has been calculated.

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.

This product is prepared in conjunction with Australia Post. The postcode tables and list product is a grouping of ten ASCII table and list files for those seeking to use Australia Post Postcode Information in textual database systems. Scale is 1:10 000 in urban areas, and 1:25 000 to 1:1m in rural areas.

The Access Network Map of England is a national composite dataset of Access layers, showing analysis of extent of Access provision for each Lower Super Output Area (LSOA), as a percentage or area coverage of access in England. The ‘Access Network Map’ was developed by Natural England to inform its work to improve opportunities for people to enjoy the natural environment. This map shows, across England, the relative abundance of accessible land in relation to where people live. Due to issues explained below, the map does not, and cannot, provide a definitive statement of where intervention is necessary. Rather, it should be used to identify areas of interest which require further exploration. Natural England believes that places where people can enjoy the natural environment should be improved and created where they are most wanted. Access Network Maps help support this work by providing means to assess the amount of accessible land available in relation to where people live. They combine all the available good quality data on access provision into a single dataset and relate this to population. This provides a common foundation for regional and national teams to use when targeting resources to improve public access to greenspace, or projects that rely on this resource. The Access Network Maps are compiled from the datasets available to Natural England which contain robust, nationally consistent data on land and routes that are normally available to the public and are free of charge. Datasets contained in the aggregated data:•
Agri-environment scheme permissive access (routes and open access)•
CROW access land (including registered common land and Section 16)•
Country Parks•
Cycleways (Sustrans Routes) including Local/Regional/National and Link Routes•
Doorstep Greens•
Local Nature Reserves•
Millennium Greens•
National Nature Reserves (accessible sites only)•
National Trails•
Public Rights of Way•
Forestry Commission ‘Woods for People’ data•
Village Greens – point data only Due to the quantity and complexity of data used, it is not possible to display clearly on a single map the precise boundary of accessible land for all areas. We therefore selected a unit which would be clearly visible at a variety of scales and calculated the total area (in hectares) of accessible land in each. The units we selected are ‘Lower Super Output Areas’ (LSOAs), which represent where approximately 1,500 people live based on postcode. To calculate the total area of accessible land for each we gave the linear routes a notional width of 3 metres so they could be measured in hectares. We then combined together all the datasets and calculated the total hectares of accessible land in each LSOA.

It has been superseded by: https://environment.data.gov.uk/dataset/f81508d3-cf5a-44ed-ae7e-452be665af84 This dataset is a product of a national assessment of flood risk for England produced using local expertise. It is produced using the Risk of Flooding from Rivers and Sea data which shows the chance of flooding from rivers and/or the sea, based on cells of 50m. Each cell is allocated one of four flood risk categories, taking into account flood defences and their condition.

This dataset uses OS address data and Royal Mail postcode data to show how many properties are in each of four flood risk categories in each postcode, based simply on the category allocated to the cell that each property is in.

NOTE: We have paused quarterly updates of this dataset. Please visit the “Pause to Updates of Flood Risk Maps” announcement on our support pages for further information. We will provide notifications on the Check Your Long-Term Flood Risk website to indicate where we have new flood risk information.

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.

This dataset is based on the data provided by the Central Bureau voor de Statistiek on different statistical metrics at the postcode level.Only the 4-digit postcodes (PC4) are available, the 5-digit and 6-digit are not freely available from the Dutch authorities.Enhancements- add administrative hierarchy: Gemeenten and Provincie.
