Previously, both Alderney and Sark were covered by the GY9 district. In March 2009, Royal Mail had "agreed in principle" for the creation of the GY10 district which would cover all addresses on the island of Alderney, leaving just those of smaller Sark in GY9. This was intended to reduce the amount of mail being sent to the wrong island.The States of Alderney opposed doing it that way round, and instead Sark changed from sector GY9 0 to GY10 1 on 5 January 2011.
The Channel Islands are an archipelago in the English Channel, off the French coast of Normandy. They include two Crown Dependencies: the Bailiwick of Jersey, which is the largest of the islands; and the Bailiwick of Guernsey, consisting of Guernsey, Alderney, Sark, Herm and some smaller islands. They are considered the remnants of the Duchy of Normandy and, although they are not part of the United Kingdom, the UK is responsible for the defence and international relations of the islands. The Crown dependencies are not members of the Commonwealth of Nations, nor have they ever been in the European Union. They have a total population of about 170,499, and the bailiwicks' capitals, Saint Helier and Saint Peter Port, have populations of 33,500 and 18,207, respectively.
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, 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.
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 Bailiwick of Guernsey is one of three Crown Dependencies.
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 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.
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.
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.
Postcodes were introduced in the Isle of Man in 1993, with the island becoming the IM postcode area. Each town or area is associated with one or more postal districts, assigned by Isle of Man Post Office. Outside the larger towns, the postal districts are further broken down and each postal sector is assigned to a number of villages and settlements.
