Detailed map of UK postcodes
editable, scalable, royalty free, vector map base
This highly detailed editable base map has all the UK postcode districts – 3,064 districts in total. Postcode districts are the alphanumeric identifiers used in the first part of a postcode, e.g. L1, CR2, EH46 for districts in Liverpool, Croydon and Edinburgh, respectively.
The editable Illustrator version of this map contains all of the UK postcode districts as interlocking layers grouped by postcode area. For example, the OX (Oxford) postcode area contains a group of layers for OX1 to OX49. This makes it easy to select individual districts and groups of districts for colour editing.
Scaling for the detailed map of UK postcodes
This map is recommended for professional cartographers and graphic designers who understand how to scale and output vector artwork. It is a complex piece of vector artwork with more than half a million anchor points.
The smallest postcode districts on this map are legible only when the map is blown up to large poster size. Therefore, you will need to tile the map (break it up into a series of smaller images, such as in an atlas) or zoom into metropolitan areas to make sensible use of it according to your needs.
In its opening state, the Illustrator version of this map is nominally 5291 x 7900 pixels within the artboard area (see the zoom examples for coverage), with the Channel Islands and Shetland extending beyond the artboard. The three images below show that the dense postcode districts of Liverpool are not legible at 100% in the opening state of the Illustrator file – you have to zoom to about 200% to read them.
Fonts are editable and scalable. You can also turn off the labelling with a single click if, for example, you want to show the postcode area names and district boundaries but not district codes.
If you only need to show the postcode areas – i.e. OX, SO, AB, etc without the numbers – you will be better off with the simpler UK POSTCODES MAP, which is cheaper and less complex to work with.
We also have a detailed LONDON POSTCODES MAP, which focuses on the central London postcode districts and gives greater detail in the innermost postcode districts, such as SW1V, EC4M, W1C, etc.
Map sources, copyright and limitations
We have used a variety of sources to create this extremely detailed map, including a vector base kindly supplied by Andrew Scott at GB Maps, plus OpenStreetMap, the Maproom Map of London Postcodes and Political Map of the UK/United Kingdom, Wikipedia and Free Postcode Maps.
Our sources are derived in part from Royal Mail data © Royal Mail, Ordnance Survey OpenData and National Statistics data © Crown Copyright.
To the best of our knowledge, the postcode district shapes and labels are accurate as of 2013, but we do not guarantee their accuracy. The shapes of small metropolitan districts are more detailed than the shapes of larger districts to reflect the likelihood of zooming into dense areas in order to make the labels legible. If any inaccuracies are found, we will correct the map and resupply it free of charge to customers.
