What is the ZIP Code of London?

Zipcodes are not used by the Royal Mail. They use a far more sophisticated system known as Post Codes. The code is a combination of letters and numbers, with the first one or two characters indicating the “post town” and the following one or two numbers indicating a subdivision of that post town delivery area (and in more rural areas that subdivision can be quite a long way from the post town).

Then there’s a space, a number, and two more letters. That space-separated section can be used to identify a group of houses (rarely more than 30) or even a company department. It is entirely possible to address something using only the house number and postcode (I tried it!). The United Kingdom does not have “Zip codes.” It contains “Postcodes.” These work on a very local scale, with each postcode typically covering a few dozen private addresses or a handful of commercial ones.

The postcode is divided into three sections, the first of which is alphabetic and denotes a town, city, or London area, the second a numeric sub-area, and the third a discrete alphanumeric local area denotes for the most granular level.

So, for example, completely at random,

East London sub-area 17 local signifier 8EG for odd-numbered houses in Harris street is E17 8EG. NW1 3SX is the local signifier for a number of Flats in Richmond House Park Village East in North West London sub-area 1. On the internet, you can use the Royal Mail Postcode Finder to look up addresses and related postcodes.

Postcodes are another name for postal codes in the United Kingdom. The first postcode system divided London and other major cities in the United Kingdom. A full postcode denotes a geographic area with multiple addresses or a single major delivery point.

Are there ZIP codes in the UK?

Postcodes are postal codes used in the United Kingdom, British Overseas Territories, and Crown Dependencies (originally, postal codes). They are alphanumeric and were implemented nationally between 11 October 1959 and 1974, after being designed by the General Post Office (Royal Mail).

What is a valid postcode in the UK?

Advice on how to record valid postcodes: The postcode is a five to seven-letter/number combination that defines four different levels of a geographic unit. It is part of a coding system developed and used by the Royal Mail to sort mail across the United Kingdom.

LONDON POSTCODES are used to categorize central London areas. Each small section of London is given a 1-3 letter prefix that corresponds to its compass location, followed by a number and two letters to distinguish it from neighboring streets in that area. In urban areas, a postcode used in a SatNav will typically take you within 50 yards of your intended destination.

What is the ZIP Code of London?

The London postal district is a 241 square mile (620 km2) area in England where mail addressed to the London post town is delivered.

The General Post Office, under the Postmaster-control, General’s directed Sir Rowland Hill to design the area in 1856, and it has been subject to reorganization and division into increasingly smaller postal units throughout its history, with the early loss of two compass points and a minor retraction in 1866.

The Post Office incorporated it into the national postcode system of the United Kingdom in the early 1970s, and it corresponds to the N, NW, SW, SE, W, WC, E, and EC postcode areas.

The postal district has also been referred to as the postal area of London. The County of London was much smaller, at 117 square miles (300 km2), but Greater London, at 607 square miles, is much larger (1,570 km2). Zipcodes are part of the American postal system. The United Kingdom employs postcodes. Typically, a postcode refers to about 15 properties.

There is no such thing as a London-wide code.

London has the following postal regions which are further divided into local postcodes.

  1. S – South
  2. Ñ – North
  3. E – East
  4. W – West
  • WC – West Central for inner London.
  • EC – East Central for inner London but pretty much the old City of London
  • NW – Northwest London
  • SW – South West includes some inner west London but mainly south west London
  • SE – South East.

In addition, due to the massive area of Greater London, some of it is covered by postcodes for areas that were always outside the London postal districts so, EN, UB, RM, and a few others I’ve forgotten.

I believe there is even a sliver of a London postcode in the E4 area, which is outside the M25, the London Orbital Motorway, which many regards as a de facto London boundary. If you look/search, there are plenty of questions and answers about London postcodes, their history, and other such topics on the internet.

These were based on points of the compass:

  • North (N)
  • North-West (NW)
  • North-East (NE)
  • South (S)
  • South-West (SW)
  • South-East (SE)
  • East (E)
  • West (W)
  • Then the two central districts
  • East Central (EC)
  • West Central (WC)

Later, South was abolished and merged with SE and SW, as was NE, which merged with E. Each district has a ‘Head District,’ which is where the primary district sorting office is located (this is not always the case today), with sub-sorting offices where the ‘walks’ for delivery are assembled around the rest of the district.

For example, the SW postal district straddles the Thames, but its Head District (SW1) was in the vicinity of Westminster, where the Post Office anticipated the highest volume and the most important mail.

The remainder of the district was divided into sub-districts that were sequentially numbered based on the initial letter of the town or center in which the local office was located. This district was a center of population growth, which resulted in additional divisions and the creation of a new Head District SW11; similarly, the satellites were numbered in the same manner:
