The GY postcode area, also known as the Guernsey postcode area, is a group of postal districts covering Guernsey, Alderney & Sark.
Coverage
The approximate coverage of the postal districts. The post town is Guernsey for all postcode districts
In March 2009, it was reported that Royal Mail had "agreed in principle" for the creation of a GY10 postcode district that would cover all addresses on the island of Alderney, to reduce confusion with addresses on the island of Sark. The proposal was opposed by the States of Alderney and consequently it was Sark's postcodes that were subsequently changed, from sector GY9 0 to sector GY10 1, on 5 January 2011.

List of postcode areas in the United Kingdom
For the purposes of directing mail, the United Kingdom is divided by Royal Mail into postcode areas. The postcode area is the largest geographical unit used and forms the initial characters of the alphanumeric UK postcode. There are currently 121 geographic postcode areas in use in the UK and a further 3 often combined with these covering the Crown Dependencies of Guernsey, Jersey and Isle of Man.
Subdivision
Each postcode area is further divided into post towns and postcode districts. There are on average 20 postcode districts to a postcode area. The London post town is instead divided into several postcode areas.
Scope
The single or pair of letters chosen for postcode areas are generally intended as a mnemonic for the places served. 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. 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.
