UK postcode lookups, based on the National Statistics Postcode Lookup published by ONS in May 2020

Geoplan has over 40 years’ experience of creating and maintaining industry standard Postcode geography in the UK, and beyond.

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.

This file contains the National Statistics Postcode Lookup (NSPL) for the United Kingdom as at May 2025 in Comma Separated Variable (CSV) and ASCII text (TXT) formats. To download the zip file click the Download button. The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England, Wales, Scotland and Northern Ireland.

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.

List of UK out code postcodes with their latitude and longitude coordinates.

The UK postal system uses postcodes to help with automating the sorting and delivery of mail. This is made up of a 2-part code, an out code and an in code. As the out code is the most significant part of the system, it can be used to obtain a rough area level break up of the UK. There are approximately 2971 out codes and approximately 1762460 full postcodes (out code + in code).

It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, which provides geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations.

Context

This open dataset takes each British postcode, locates the centroid, and assigns an elevation based on the nearest point on an Ordnance Survey contour line to that centroid.

Also known as altitude, elevation is given as distance above sea level in metres.

• Total persons recorded in that postcode
• Female or male breakdown of the postcode
• Number of occupied households in that postcode
• The Lower Super Output Area or Data Zone in which the postcode resides
• The Output Area or Small Area in which the postcode resides
• The Output Area's Classification:
  • OAC Supergroup (codes and names)
  • OAC Group (codes and names)
  • OAC Subgroups (codes and names)
• The Deprivation Ranks of the LSOA/DZ:
  • 2014 Welsh Index of Multiple Deprivation (WIMD) Rank for 2011 LSOAs

Suppressed postcodes in Northern Ireland

For confidentiality reasons, counts were suppressed for postcodes that had less than 10 usual residents and had only 1, 2 or 3 households in them.

The Registrar General took steps to ensure that the confidentiality of respondents was fully protected. Accordingly, all published results from the 2011 Census (including those relating to Postcodes) were subject to statistical processes to ensure that individuals could not be identified. For these postcodes, averages were taken at Postcode District level and released in a separate table, which can be found below.

Missing postcodes

These postcodes are based upon the sets of enumeration postcodes provided by the three UK census agencies. Enumeration postcodes are a subset of the complete set of live postcodes at the time of the 2011 Census. These are aggregated to create census output areas, which are themselves aggregated to create most other census geographies.

Only postcodes with at least one resident person are included. Many postcodes, such as those assigned to businesses, don't have any resident populations and so won't appear in the table.

Postcodes are quite volatile; new postcodes are created and old ones are terminated regularly. Existing/live postcodes can also change through the addition or removal of delivery points. The ONSPD records all live and terminated postcodes. Each postcode has a date of introduction and, if relevant, a date of termination. Things are complicated further because postcodes can be re-used, so a postcode can be terminated and then reappear with a new date of introduction, replacing/removing the record for the previous instance of the postcode. Postcodes that weren't current at the time of the census also won't appear in the table.
