List of postcode areas in the United Kingdom

Last updated

The list of postcode areas in the United Kingdom is a tabulation of the postcode areas used by Royal Mail for the purposes of directing mail within the United Kingdom. The postcode area is the largest geographical unit used and forms the initial characters of the alphanumeric UK postcode. [1] There are currently 121 geographic postcode areas in use in the UK and a further three often combined with these covering the Crown Dependencies of Guernsey, Jersey and Isle of Man.



Each postcode area is further divided into post towns and postcode districts. [1] There are on average 20 postcode districts to a postcode area. [1] The London post town is instead divided into several postcode areas. [2]


The single or pair of letters chosen for postcode areas are generally intended as a mnemonic for the places served. [1] Postcode areas, post towns and postcode districts do not follow political boundaries and usually serve much larger areas than the place names with which they are associated. For example, within the PA postcode area the PA1 and PA78 postcode districts are 140 miles apart; and the eight postcode areas of the London post town cover only 40% of Greater London. [2] The remainder of its area is covered by sections of twelve adjoining postcode areas: EN, IG, RM, DA, BR, TN, CR, SM, KT, TW, HA and UB. [2]

Defunct postcode areas

London NE and S


Glasgow, like London, was divided into compass districts: C, W, NW, N, E, SE, S, SW. When postcodes were introduced, these were mapped into the new G postcode: C1 became G1, W1 became G11, N1 became G21, E1 became G31, S1 became G41, SW1 became G51, and so on. As NW and SE had never been subdivided they became G20 and G40 respectively.

Norwich and Croydon

Norwich and Croydon were used for a postcode experiment in the late 1960s, which was replaced by the current system. The format was of the form NOR or CRO followed by two numbers and a letter, e.g. NOR 07A. They were later changed to CR0 (digit '0') and NR1.

Dublin, Ireland

When Ireland was a part of the United Kingdom of Great Britain and Ireland a postal district system was introduced in 1917 by the UK government. The letter D was assigned to Dublin. Upon the establishment of the Irish Free State and later, the Republic of Ireland, the Irish government retained the designation and today it forms part of the Eircode system. Interestingly, the postcode was never reassigned within the United Kingdom after Irish independence and there is no D postcode area in the UK to this day. Modern postcodes used in Dublin, and the Republic of Ireland generally, take a slightly different form from UK postcodes and are specific to individual addresses.

Non-geographic postcodes

Note that a number of non-geographic postcode sectors are also contained within geographic postcode areas.


GIR 0AA is a postcode created for Girobank in Bootle. It remained in use by its successors when Girobank was taken over by Alliance & Leicester and subsequently by Santander UK.


The BF postcode area was introduced in 2012 to provide optional postcodes for British Forces Post Office addresses, for consistency with the layout of other UK addresses. It uses the national non-geographic post town "BFPO" and, as of 2012, the postcode district "BF1".


The non-geographic postcode area BX has been introduced for addresses which do not include a locality: this allows large organisations long-term flexibility as to where they receive their mail. This postcode area is used by Lloyds Banking Group (BX1 1LT), HSBC (BX8 0HB) and parts of the HM Revenue and Customs like VAT Central Unit (BX5 5AT) and Pay as You Earn (BX9 1AS). Lloyds Bank also use BX4. After splitting from Lloyds, TSB Bank uses BX4 7SB, the latter part of which, when written, looks similar to "TSB".


The non-geographic postcode area XX is used by online retailers for returns by Royal Mail, and for COVID-19 test samples.

Overseas territories

Certain British Overseas Territories introduced single postal codes for their territory or major sub-sections of it. These are not UK postcodes, even though many are formatted in a similar fashion:

Civilian residential and business addresses in Akrotiri and Dhekelia are served by Cyprus Postal Services and use Cypriot postal codes.

Mail to Overseas Territories is treated as international if posted in the UK.

    A postal code is a series of letters or digits or both, sometimes including spaces or punctuation, included in a postal address for the purpose of sorting mail.

    Postcodes in the United Kingdom

    Postal codes used in the United Kingdom, British Overseas Territories and Crown dependencies are known as postcodes. They are alphanumeric and were adopted nationally between 11 October 1959 and 1974, having been devised by the General Post Office. A full postcode is known as a "postcode unit" and designates an area with several addresses or a single major delivery point.

    London postal district post town

    The London postal district is the area in England of 241 square miles (620 km2) to which mail addressed to the London post town is delivered. The General Post Office under the control of the Postmaster General directed Sir Rowland Hill to devise the area in 1856 and throughout its history it has been subject to reorganisation and division into increasingly smaller postal units, with the early loss of two compass points and a minor retraction in 1866. It was integrated by the Post Office into the national postcode system of the United Kingdom during the early 1970s and corresponds to the N, NW, SW, SE, W, WC, E and EC postcode areas. The postal district has also been known as the London postal area. The County of London was much smaller, at 117 square miles (300 km2), but Greater London is much larger at 607 square miles (1,570 km2).

    W postcode area Postcode area within the United Kingdom

    The W postcode area, also known as the London W postcode area is a group of postcode districts covering part of central and part of West London, England. The area originates from the Western (W1) and Paddington (W2-14) districts of the London postal district. This area covers 35 postcode districts and around 18,554 live postcodes.

    Postal counties of the United Kingdom Subdivision of the United Kingdom

    The postal counties of the United Kingdom, now known as former postal counties, were postal subdivisions in routine use by the Royal Mail until 1996. The purpose of the postal county – as opposed to any other kind of county – was to aid the sorting of mail by differentiating between like-sounding post towns. Since 1996 this has been done by using the outward code of the postcode instead. For operational reasons the former postal counties, although broadly based on the counties of the United Kingdom, did not match up with their boundaries: in some cases there were significant differences. The boundaries changed over time as post towns were created or amended.

    Mailsort was a five-digit address-coding scheme used by the Royal Mail and its business customers for the automatic direction of mail until 2012. Mail users who could present mail sorted by Mailsort code and in quantities of 4,000 upwards receive a discounted postal rate.

    E postcode area United Kingdom postcode area

    The E (Eastern) postcode area, also known as the London E postcode area, is the part of the London post town covering much of the east of Greater London, England as well as Sewardstone, Essex. It borders the N postcode area to the west, both north of the tidal Thames. Since closure of the East London mail centre its mail is sorted at Romford Mail Centre together with IG and RM postcode areas.

    An address is a collection of information, presented in a mostly fixed format, used to give the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers and organization name. Some addresses also contain special codes, such as a postal code, to make identification easier and aid in the routing of mail.

    A post town is a required part of all postal addresses in the United Kingdom and Ireland, and a basic unit of the postal delivery system. Including the correct post town in the address increases the chance of a letter or parcel being delivered on time. Post towns in general originated as the location of delivery offices. As of 2004, their main function is to distinguish between localities or street names in addresses not including a postcode.

    Postal addresses in the Republic of Ireland Postal code system of Ireland

    A "postal address" in the Republic of Ireland is a place of delivery defined by Irish Standard (IS) EN 14142-1:2011 and serviced by the universal service provider, An Post. Its addressing guides comply with the guidelines of the Universal Postal Union (UPU), the United Nations-affiliated body responsible for promoting standards in the postal industry, across the world.

Postcodes in Australia have four digits and are placed at the end of the Australian address, before the country. Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department and are now managed by Australia Post, Australia's national postal service. Postcodes are published in booklets available from post offices or online from the Australia Post website.

    The British Overseas Territory of Gibraltar has introduced the postcode GX11 1AA. This is pending the introduction of a postcode system similar to that used in the United Kingdom. This has been under consideration by the Government of Gibraltar since 2006. The postcode is not required for local mail.
