Code-Point with Polygons

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.

This product is updated quarterly in January, April, July and October.

Visualise postcode extents

Codepoint with Polygons provides notional extents for every postcode unit in GB for easy visualisation and analysis at a national scale.

Vertical street polygons

Vertical street polygons allow easy identification of multiple postcodes within the same building.

Precise polygon data

Postcode polygons created using the addresses we can locate the most precisely creating high confidence in the accuracy of the polygon data.

Manage your risks better

Display postcode boundaries on a map, then add contours and your own claims data. This is a great way to identify low-lying postcodes, so you can quote for insurance at a price that reflects higher flood risks.
