The second more detailed level is called Postcode District. The UK is broken down into approximately 3000 postcode districts which are denoted by the first 2 or 3 characters of your postcode eg. B1, B2, or OX1, OX2 etc. These District boundaries are depicted on our 6 Postcode District maps.
In addition, we are able to create bespoke Postcode District maps centred on your own choice of location, please call us for a price.
