ONS Postcode Directory (August 2025) for the UK (Hosted Table)

This is the ONS Postcode Directory (ONSPD) for the United Kingdom as at August 2025 in Comma Separated Variable (CSV). This is a new hosted table so can be accessed via API. 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 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 also contains 2021 Census OAs and SOAs for England, Wales and Northern Ireland and 2022 Census OAs DZs and Intermediate Zones (IZ) for Scotland. 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.

Rural Urban Classification (2021) of Senedd Constituencies (2022) in WA

Rural Urban Classification The 2021 RUC is a statistical classification to provide a consistent and standardised method for classifying geographies as rural or urban. This is based on address density, physical settlement form, population size, and Relative Access to Major towns and cities (populations of over 75,000 people). The classification is produced by the Office for National Statistics (ONS) with advice from the Department for Environment, Food and Rural Affairs (Defra), the Welsh Government and colleagues from the Government Geography Profession (GGP). This is 2021 rural-urban classification (RUC) of the 2022 Senedd Constituencies for Wales. This means that the 2021 RUC methodology has been applied to the 2022 Senedd Constituency boundaries. Senedd Constituency classifications are divided into four categories based on their populations: 1. Majority Rural: had at least 50% of their population residing in Rural OAs 2. Intermediate Rural: 35-50% rural population 3. Intermediate Urban: 20-35% rural population 4. Urban: 20% or less of the population lived in rural OAs. Each 2022 Senedd Constituency category is split into one of two Relative Access categories, using the same data as the 2021 Output Area RUC. If more than 50% of a population lives in ‘Nearer a major town or city’ OAs, it is deemed ‘nearer a major town or city’; otherwise, it is classified as ‘further from a major town or city’. Where data is unavailable for Super Output Area geographies, it may be appropriate for users to undertake analysis at the Senedd Constituency level. At this level, the categorisation works slightly differently in that most areas will include a mix of both rural and urban areas - so the Constituency RUC categorisation is a reflection of this. A statistical geography may contain substantial portions of open countryside but still be given an ‘Urban’ classification if the majority of the population within the area live in settlements that are urban in nature. Users should take this into consideration to ensure correct interpretations of any analysis of RUC Senedd Constituency categories.”
Rural Urban Classification (2021) of Upper Tier Local Authorities (2023) in EW

Rural Urban Classification The 2021 RUC is a statistical classification to provide a consistent and standardised method for classifying geographies as rural or urban. This is based on address density, physical settlement form, population size, and Relative Access to Major towns and cities (populations of over 75,000 people). The classification is produced by the Office for National Statistics (ONS) with advice from the Department for Environment, Food and Rural Affairs (Defra), the Welsh Government and colleagues from the Government Geography Profession (GGP). This is 2021 rural-urban classification (RUC) of 2023 Upper Tier Local Authorities (UTLA) in England and Wales. This means that the 2021 RUC methodology has been applied to the 2023 UTLA boundaries. UTLA classifications are divided into four categories based on their populations: 1. Majority Rural: had at least 50% of their population residing in Rural OAs 2. Intermediate Rural: 35-50% rural population 3. Intermediate Urban: 20-35% rural population 4. Urban: 20% or less of the population lived in rural OAs. Each 2023 UTLA category is split into one of two Relative Access categories, using the same data as the 2021 Output Area RUC. If more than 50% of a UTLA population lives in ‘Nearer a major town or city’ OAs, it is deemed ‘nearer a major town or city’; otherwise, it is classified as ‘further from a major town or city’. It may be appropriate for users to undertake analysis at the UTLA level to get a broad idea of the overall classification of an area, but more detailed classification information will be available for the component Local Authority Districts. At the UTLA level, the categorisation works slightly differently in that most areas will include a mix of both rural and urban areas - so the UTLA RUC categorisation is a reflection of this. A statistical geography may contain substantial portions of open countryside but still be given an ‘Urban’ classification if the majority of the population within the area live in settlements that are urban in nature. Users should take this into consideration to ensure correct interpretations of any analysis of RUC UTLA categories, and should consider whether LAD level classification is more appropriate for their purposes.”
