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. As of 2004 [update] , their main function is to distinguish between localities or street names in addresses not including a postcode.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.
There are approximately 1,500 post towns which are organised by Royal Mail subject to its policy only to impose changes where it has a proven, economic and practical benefit to the organisation, covering its own cost.Each post town usually corresponds to one or more postal districts (the 'outward' part of the postcode, before the space) therefore each post town can cover an area comprising many towns, urban districts and villages. Post towns rarely correspond exactly to administrative boundaries and their associated physical features. As such they often group a small minority of neighbourhoods, streets or houses together with a main settlement in a different county, area of local government or administration (including healthcare trust), constituency, European statistical region and/or traditional parish. This was a main reason why postal counties were abolished (but not prohibited) in 1996.
In some places several post towns cover a single postal district (with each post town corresponding to one or more of its postcode sectors). There are anomalies where post towns and postcode sectors have a more unusual co-relation. For example, the postcode sector EH14 5 is split between three post towns: Juniper Green, Currie and Balerno. Its other postcode sectors are generally one of these, Balerno.
The Royal Mail states that the post town must be included on all items and should be clearly written in capitals.
The use of postcodes means that it is no longer necessary to include the former postal county in a postal address. Some post towns, known as special post towns, never required the inclusion of a postal county, either because the town was large or because it gave its name to the county.
In most places, additional locality information such as a village or suburb name is optionally added above the post town, giving a more specific location: the two largest 'post town' cities named, for example, have many roads of the same name in different localities and the additional locality information is therefore essential if the postcode is wrongly recorded or unknown.
Where this is a disambiguating feature, Royal Mail terms this the "dependent locality". For a limited number of addresses a "double dependent locality" line is also required, preceding the dependent locality line.
Locality information other than the post town is not always part of the official postal address. In particular, within the London post town, each postcode district name (which can conflict with administrative boundaries, see above) corresponds to a numbered postcode district and is therefore not required in the postal address whenever the postcode is used. For example, "Bethnal Green" is the name of the "E2" postcode district and is optional in the following address:
If no valid postcode is provided, or if the sorting machine rejects the letter, the use of optional locality or county information may assist manual sorting. In the absence of a full valid postcode, locality often prevents ambiguity where there is more than one street with the same name covered by a post town or postcode district, or where post towns in different counties have the same name.
Traditionally only, where a place such as a village was served by a post town entirely distinct from its location, the word "Via" or "Near" ("Nr.") was added before the post town. For example:
However, the Royal Mail discourages this usagebecause their optical character recognition technology and Mailsort lookup tables check for the post town at the beginning of a line if the postcode is missing, unreadable or incorrect. Additionally, "Near" and "Nr." can be confused with "North".
Post town names are unique within each former postal county and each postcode area (the initial letter or two letters of the post code). But across the UK, some post towns have identical or similar names. For Mailsort purposes, post towns in unpostcoded addresses can be pre-sorted only if the first 10 characters of the post town name correspond unambiguously to only one post town. In addition, the following post towns have shared sorting routes or cover such large locations that the town name is insufficient for determining the relevant delivery area without reference to the postcode or further locality information:
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.
Postal codes used in the United Kingdom 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 a number of addresses or a single major delivery point.
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 at the control of the Postmaster General directed Sir Rowland Hill to devise the area in 1856 and throughout its history has been subject to gradual periodic 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).
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.
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.
The Postcode Address File (PAF) is a database that contains all known "Delivery Points" and postcodes in the United Kingdom. The PAF is a collection of over 29 million Royal Mail postal addresses and 1.8 million postcodes. It is available in a variety of formats including FTP download and compact disc, and was previously available as Digital Audio Tape. As owner of the PAF, Royal Mail is required by section 116 of the Postal Services Act 2000 to maintain the data and make it available on reasonable terms. A charge is made for lookup services or wholesale supply of PAF data. Charges are regulated by Ofcom. It includes Small User Residential, Small User Organisation and Large User Organisation details. There have been requests as part of the Open Data campaign for the PAF to be released by the government free of charge.
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.
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, equally north of the tidal Thames. Since closure of the East London mail centre its mail is sorted at Romford Mail Centre as for 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.
The WC postcode area, also known as the London WC postcode area, is a group of postcode districts in central London, England. The area covered is of high density development, and includes parts of the City of Westminster and the London Boroughs of Camden and Islington, plus a very small part of the City of London.
The TW postcode area, also known as the Twickenham postcode area, is a group of 20 postcode districts in England, within 13 post towns. These cover parts of south-west London and north-west Surrey, plus a very small part of Berkshire.
A "Postal Address" is a delivery address as defined by Irish Standard - I.S. EN 14142-1:2011, as operated by the Universal Service Provider, An Post. Their addressing guides comply with the addressing guidelines of the Universal Postal Union.
The UB postcode area, also known as the Southall postcode area, is a group of eleven postcode districts in England, within six post towns. These cover parts of west and north-west London, plus a very small part of Buckinghamshire. The letters in the postcode are derived from an abbreviation of Uxbridge.
The GU postcode area, also known as the Guildford postcode area, is a group of 38 postcode districts in South East England, within 24 post towns. These cover west Surrey, north-east Hampshire and northwestern West Sussex, plus a small part of Berkshire.
The NW postcode area, also known as the London NW postcode area, is a group of postcode districts covering part of northwest London, England. It is the successor of the NW sector, originally created as part of the London postal district in 1856.
The TN postcode area, also known as the Tunbridge Wells postcode area, is a group of 40 postcode districts in England, within 24 post towns. These cover south Kent and northern and eastern East Sussex. Additionally, small parts of TN14 and TN16 cover the southern part of the London Borough of Bromley, while TN16 also covers the village of Tatsfield in Surrey.
Postcodes are used in Australia to more efficiently sort and route mail within the Australian postal system. Postcodes in Australia have four digits and are placed at the end of the Australian address. Postcodes were introduced in Australia in 1967 by the Postmaster-General's Department and are now managed by Australia Post, and are published in booklets available from post offices or online from the Australia Post website.
