S postcode area

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. The code was changed while the area remained the same to avoid confusion as the sectors were redrawn. • 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. ==Coverage==

As with many postcode areas in the United Kingdom, the S Area is numbered in various clusters. S1-S14 cover the core urban area of Sheffield, with S17-S36 covering more suburban or rural areas within Sheffield's environs. Postcodes in the range S4x relate to the Chesterfield area. The range S6x relates to Rotherham. S7x relates to Barnsley, and S8x relates to Worksop. Any other postcodes prefixed S are non-geographic in nature. The approximate coverage of the postcode districts: S1-S36: SHEFFIELD, DRONFIELD and HOPE VALLEY Post Towns S40-S49: CHESTERFIELD Post Town S60-S66: ROTHERHAM and MEXBOROUGH Post Towns S70-S75: BARNSLEY Post Town S80 and S81: WORKSOP Post Town S94-S99: Non-Geographic Postcodes ==Map==
