SW postcode area
[3][5] The South Western head district was designated as SW1 and the rest of the numbering followed, alphabetically, by their most important parish, chapelry, topological or built environment feature names, up to 10.Since about the 1890s it has had a surplus of addresses and buildings for practical division into one set of inwards codes so is divided into smaller postcode districts since 1917 used for mail purposes.SW1 is used in geographic reference, street signs and colloquial use across most communities.[6][7] The SW postcode area covers parts of nine London Boroughs.North of the River Thames, it covers the southern parts of the City of Westminster, the Royal Borough of Kensington and Chelsea and the London Borough of Hammersmith and Fulham.
