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.

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.
Code-Point is created by taking the average of the coordinates of all the individual addresses in a postcode (provided we have any of sufficient quality), then snapping to the nearest of those addresses. Code-Point then delivers the coordinates of that address, as representative of the whole postcode, to a resolution of 1 metre.
The accuracy of a Code-Point Open record could be expressed as, that the coordinated position will always be within the notional geographical extent of the postcode. The accuracy of each postcode unit coordinate pair is defined by the positional quality indicator (PQI) which provides a quality statement of a Code-Point record.
