National Statistics Postcode Lookup: Geographic Centroids for the UK

February 2020 centroids for every UK postcode are provided in a single 923 MB CSV file, making it too large for shapefile download. This dataset is the authoritative National Statistics Postcode Lookup (NSPL) from the UK's official geoportal, offering a precise geographic reference for postal geography. Its cross-platform presence on EU and UK open data portals signals its importance as a foundational geospatial resource.

Use Cases

• Mapping customer or survey data based on postcode centroids.
• Calculating distances or service areas using precise geographic coordinates for postcodes.
• Enriching business intelligence datasets with a standardized UK geographic lookup.
• Performing spatial joins between postcode areas and other administrative boundaries.

Strengths

• File size of 923 MB suggests a large, likely complete coverage of UK postcodes.
• Sourced from the authoritative UK Government Digital Service geoportal.
• Available via multiple access methods (CSV, REST services) indicating robust infrastructure.

Limitations

• Metadata is incomplete: column names, row count, and specific license are not provided.
• The data is from February 2020, which may not reflect recent postcode changes.
• Conflicting 'last updated' dates (2020-02-18 vs. 2026-07 08) create uncertainty about provenance.
