Code-Point with Polygons is a dataset that contains the notional area of postcode units, designed to allow customers to display and analyse any data collected at the postcode level. Polygons within this product are derived from georeferenced Royal Mail Postal Address File (PAF) delivery addresses and processed using a Thiessen process to create mathematically consistent boundaries between distinct postcode groups as a notional boundary set.

Codepoint with Polygons provides notional extents for every postcode unit in GB for easy visualisation and analysis at a national scale.
Vertical street polygons allow easy identification of multiple postcodes within the same building.
Postcode polygons created using the addresses we can locate the most precisely creating high confidence in the accuracy of the polygon data.
