Geoplan Postcode Sector maps provide high-detail local mapping of the UK overlaid with postcode sectors, country boundaries & larger postcode groupings. They are durable & laminated, so you can draw on them in non-permanent markers & wipe them clean. They are the market-leader postcode maps for marketing, statistical display, route-planning, strategy & many other business uses. The base map uses the latest Ordnance Survey Landranger cartography, which provides detailed geographic data including motorways, A & B roads, streets, & detailed feature types such as airports, railway stations, cities, towns, geographic names, heights (using contour lines), information centres, parking facilities & much more. The base map is light & subtle but clear, readable & now in colour. Postcode/county boundaries & labels are overlaid in a bold red. The Postcode system divides the UK into Areas, Districts & Sectors. Geoplan publish maps covering all of these levels. These Sector maps cover 37 small areas of the UK, showing postcode Sectors (like HG3 1, B10 9, WC2 9 etc), their larger Districts (HG3, B10, WC2 etc) & the even larger Areas (HG, B, WC etc)
