The postcode area originated in 1857 as the SW district. In 1868 it gained some of the area of the very short-lived S district, with the rest going to SE. It was divided into numbered districts in 1917. The South Western district consists of the postcode districts SW1–SW10 and the once Battersea-headquartered component consists of the postcode districts SW11–SW20. 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. Similarly as to the Battersea SW11 once "head district".
