S postcode area

The S postcode area, also known as the Sheffield postcode area, is a group of postcode districts in England, which are subdivisions of eight post towns. These cover most of South Yorkshire (including Sheffield, Barnsley, Rotherham and Mexborough), parts of north Derbyshire (including Chesterfield, Dronfield and the Hope Valley) and north-west Nottinghamshire (including Worksop), plus a small part of West Yorkshire. The S postcode area is one of six with a population above 1 million.

History
For 1857–1868 an S sector of the London postal district existed.

Similarly, there were also S-prefixed postal districts in the compass-based system used in Glasgow: Glasgow S1, S2, S3 and S4, which later became G41 to G44.

Three postcode districts were split and separated into ten new postcode districts. These were:
 * S20, formed out of S19
 * S21, S25 and S26, formed out of S31
 * S32 to S36, formed out of S30.

The S64 district covering the Mexborough post town was originally earmarked for use as DN13, which has never been used.
