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.

The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2011 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations). It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

Code-Point® with polygons shows the notional shape of every postcode unit in Great Britain, and includes major buildings with multiple postcodes.

For compelling visuals, Code-Point with polygons lets you apply shading to individual postcodes on a map. This means you can analyse location data at the most granular level and bring your results vividly to life.

We give you every single postcode in Great Britain and Northern Ireland – including those for different floors of high-rise buildings.

For accuracy, we give every postcode a positional quality rating and map out the boundaries of only the postcodes we can locate most precisely.

City map with postcodes boundaries

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 dataset is part of the Geographical repository maintained by Opendatasoft.This dataset contains data for zip codes 5 digits in United States of America.ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery.Processors and tools are using this data.EnhancementsAdd ISO 3166-3 codes.Simplify geometries to provide better performance across the services.Add administrative hierarchy.

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.

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).

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.
