XYZ Postcode Areas
Postcode Areas are the first two letters of the Postcode (e.g. EH) and there are 120 in Great Britain, plus one each for Northern Ireland, the Isle of Man, Guernsey and Jersey. In most areas our boundaries are finely detailed and created from following real features on air photography. The Postcode Areas are shown in red on top of appropriate map backgrounds depending on the zoom level. Use the Postcode Areas to get an overview of the postcode system, to allocate sales territories, etc.
