About UK postcode areas
What is a UK postcode area?
A postcode area is the broadest unit of the UK postcode system, made up of one or two letters at the start of a postcode - such as DD for Dundee, EH for Edinburgh or M for Manchester. There are 121 geographic postcode areas across Great Britain and Northern Ireland.
How many postcode areas are there in the UK?
There are 121 geographic postcode areas in the UK. TrackPostcode.UK covers all of those in England, Scotland and Wales; the BT area, which covers Northern Ireland, is not currently covered.
Which UK postcode area has the largest population?
Among the areas we cover, the largest by approximate resident population are Manchester (M, about 2.5 million), Birmingham (B, about 2.4 million) and London (East) (E, about 1.5 million). London is split across eight postcode areas (E, EC, N, NW, SE, SW, W and WC), so no single London area tops the list. The table on this page ranks all of them.
How do I get a report for my exact postcode?
Search your full postcode or outcode (for example DD1 4HN or DD1) in the search box. That returns the most local view available: weather, amenities and air quality for the exact point, crime too in England and Wales, and cost, housing and other statistics for the surrounding council area.
What is the difference between a postcode area, district and full postcode?
A postcode area is the letters only (DD). A district or outcode adds a number (DD1). A full postcode adds the inward code too (DD1 4HN) and covers just a handful of addresses. Reports are most local when you search a full postcode or outcode.
