The SK postcode area, also known as the Stockport postcode area,[2] is a group of nineteen postcode districts in England, within eleven post towns. These cover south-east Greater Manchester (including Stockport, Cheadle, Hyde, Stalybridge and Dukinfield), parts of east Cheshire (including Macclesfield, Wilmslow and Alderley Edge), north-west Derbyshire (including Buxton, High Peak and Glossop) and a small part of north Staffordshire.
The SK22 and SK23 districts and the HIGH PEAK post town were formed in 1996, out of the SK12 district and the STOCKPORT post town.[3]
