XYZ Postcode Boundaries - Area Level

2024 Edition Released November 2024

XYZ Postcode Area Boundaries have been upgraded to our New "Xtreme Accuracy" Standard. This means the Boundaries are re-Digitised so they not only Fit around the Postcode Points but Now Follow Real Physical Features on Air Photography, such as Streams, Railways, Fences, Walls and Roads.

Postcode Areas are the top level of the UK postcode system and are indicated by the first two (in a few cases one) letter of the postcode. There are 124 postcode areas in total and the name of each area reflects the post town on which they are centred, for example EH for Edinburgh or B for Birmingham.These are one of the most widely used datasets in digital mapping, typically for sales and marketing where they can be used to do a thematic map e.g. of sales of different products geographically. The 2024 Version was released in November 2024 and is current to the Q3 PAF of 2022 release. Approximately 850 postcode sectors have been completely revised in this release since the previous edition in January 2018.

The product contains:

• Postcode Area polygons
• Postcode Area boundary lines

The lines can be styled to show the type of boundary and do not include the coastline.

The standard formats available are for ArcGIS Shape Files, MapInfo Professional Tab files or Google KML files. Please select which format you require and then download the appropriate Zip file.
