Westminster, England

The typical property in W1A

W1A is a non-geographic Royal Mail outcode used for PO Boxes and large-organisation business addresses in the West End, including the BBC (Broadcasting House) and major media firms.

Area summary

W1A is a non-geographic outcode allocated by Royal Mail for PO Boxes and large-volume business addresses in the West End. BBC Broadcasting House at Portland Place has the postcode W1A 1AA. The postcode does not correspond to a defined residential area in the same way ordinary outcodes do, it functions as a delivery-routing tag rather than a place. Property listings in W1A are extremely rare and where they appear they are usually administrative addresses (registered company offices, government departments, large utilities) rather than dwellings.

The underlying geography (West End ward of Westminster, with a small Islington overlap) is mostly commercial.
