The W (Western and Paddington) postcode area, commonly referred to as the London W postcode area, is a collection of postcode districts that includes parts of West and Central London in England. The Western (W1) and Paddington (W2-14) areas of the London postal district are where the area is located. 35 postcode districts and about 18,554 active postcodes are covered by this region. The sole original W1 postal district makes up the Western district.
Due to the high density of the area it covers, a number of smaller postcode districts have been created. The W1 subdivisions continue to be classified as one “district” when districts are used for purposes other than sorting mail, such as use as a geographic reference and on street signs.
London Central serves as the mail hub for W1, and Greenford serves as the hub for W2-14.
Until it was shut down, deliveries for W1 (as well as WC1 and WC2) came from the Western District Office on Rathbone Place. It served as a station on the defunct London Post Office Railway, which was shut down in 2003. At first, the London Post Office Railway stopped at Wimpole Street, where the Western District Office was located. There are 13 postcode districts in the Paddington district (W2–14). Other than W2, the districts are listed alphabetically and extend westward from W3 (Acton) to W14 (West Kensington). The London Post Office Railway had its western end at the Paddington Head District Sorting Office and went 6.5 miles (10.5 km) to the Whitechapel Eastern District Office.
London’s postcode districts W1 and W2 are in the city’s center, whereas W3 through W14 are primarily in the west. The area’s boundaries and its numbered districts have evolved over time as a result of the Royal Mail’s operational needs. The boundaries of the local authority areas do not match. With a minor portion in the London Borough of Camden, W1 is almost entirely located inside the City of Westminster. W2 to W14 encompass the northern portions of the City of Westminster, the London Boroughs of Ealing and Hounslow, the Royal Borough of Kensington and Chelsea, and Hammersmith and Fulham, as well as very small portions of the London Boroughs of Brent and Camden.
