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.[4] The proposal was opposed by the States of Alderney[5] and consequently it was Sark's postcodes that were subsequently changed, from sector GY9 0 to sector GY10 1, on 5th January 2011.
