|Statistics as at May 2020|
The NW (North Western) postcode area, also known as the London NW postcode area, is a group of 13 postcode districts covering around 13,895 live postcodes within part of northwest London, England. It is the successor of the NW sector, originally created as part of the London postal district in 1856.
London postal arrangements were refined in 1917 when all its postcode districts (seven radial which are large and two innermost, much smaller) became publicly sub-divided; these were named after the location of the delivery office in each district. As London is one post town, district names are deprecated, in favour of the post town LONDON to be written/typed.
Within each NW postcode district, PO boxes are allocated to a unique postcode sector, except for two districts which use all available sectors for ordinary addresses and therefore have their separate non-geographic districts: NW1W for PO boxes in NW1 and NW26 for PO boxes in NW10.

Postcode district NW1 is central to London, with the NW2–11 postcode districts radiating outwards to the northwest. The boundaries of the area and its numbered districts have changed over time and are the result of the working requirements of Royal Mail. They are not tied to those of the local authority areas served; consequently a locality name might describe varying areas. The postcode area contains large parts of London Boroughs of Barnet, Brent and Camden with small parts of the City of Westminster and those of Ealing, Hammersmith and Fulham, Harrow, Islington and Kensington & Chelsea. The NW7 district is a projection as far as Hertfordshire's near edge, which it mirrors or emulates briefly near Scratch Wood.
In popular culture
In 2012, the British author Zadie Smith released a book called NW, named after the postal district of the same name, where the novel is set. The novel was adapted into a 2016 television film by the BBC.
