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.<ref name="insight090303">{{cite news |url=http://www.guernseyinsight.com/news_1.aspx?id=2:11931&news=2:2029 |title=Alderney postcodes could soon change to GY10 |author=Island FM |date=3 March 2009 |work=Guernsey Insight |publisher=Wave Telecom |access-date=20 January 2010 |location=Jersey |url-status=dead |archive-url=https://web.archive.org/web/20110711132735/http://www.guernseyinsight.com/news_1.aspx?id=2%3A11931&news=2%3A2029 |archive-date=11 July 2011 }}</ref> The States of Alderney opposed doing it that way round,<ref name="alderney090323">{{cite web|url=http://www.alderney.gov.gg/meetings/minutes/Policy-and-Finance-Committee-23-fs-03-fs-2009 |title=Minute 22/2009 Any other business: 22.1 Change of postcode for Alderney |author=States of Alderney |date=27 April 2009 |work=Minutes of Policy and Finance Committee 23 March 2009 |access-date=20 January 2010 |location=Alderney |url-status=dead |archive-url=https://web.archive.org/web/20110926233156/http://www.alderney.gov.gg/meetings/minutes/Policy-and-Finance-Committee-23-fs-03-fs-2009 |archive-date=26 September 2011 }}</ref> and instead Sark changed from sector GY9 0 to GY10 1 on 5 January 2011.
