The SW (South Western and Battersea) postcode area, also known as the London SW postcode area[2], is a group of postcode districts in south west London, England. The area originates from the South Western (SW1-10) and Battersea (SW11-20) districts[3] of the London postal district.
The postcode area originated in 1857 as the SW district. In 1868 it gained some of the area of the abolished S district, with the rest going to SE. It was divided into numbered districts in 1917.[4]

The South Western district[3] consists of the postcode districts SW1-10.[5] The SW1 postcode district is of very high density development and has been relatively recently divided into smaller postcode districts. Where districts are used for purposes other than the sorting of mail, such as use as a geographic reference and on street signs, the SW1 subdivisions continue to be classed as one 'district'. SW99 is a non-geographic postcode used for large businesses located in the SW9 postcode district.[2] The South Western district includes postcode districts on both sides of the Thames.
