UK Postcode Lookup: Wards, Districts and Counties

This page provides a comprehensive lookup of UK postcode units, covering around 1.75 million postcodes across England, Scotland, Wales, and Northern Ireland. Each postcode is mapped to its corresponding ward, local authority district, county, and country, allowing you to understand exactly how postcodes relate to administrative geography.

Instead of static lists or individual lookups, this page offers a fully searchable and filterable dataset. Whether you are researching local government boundaries, analysing postcode coverage, or simply checking which ward or district a postcode belongs to, this table gives you fast, transparent access to the data.

This postcode lookup page focuses on individual postcode units. If you’re interested in postcode data from a broader or more structural perspective, Baseview also provides two complementary resources:

  • A page dedicated to postcode areas, where postcode areas are the main subject and their distributions across districts and outcodes are explored
  • A page focused on postcode districts (outcodes), allowing you to examine where each outcode is located and how postcodes are distributed within it

Together, these pages let you explore the UK postcode system from area → district → individual postcode, depending on your research needs.

Our tools about UK postcodes were based on OS Postcodes Data (Version Date: November 2025). The program that generated this web page was last updated on .
