Postcodes and sectors

Roads filed under W5

Named roads first, then numbered ones. A road is filed under one district even where it runs through several, so a street missing here may be listed under a neighbouring district — which is why the address lookup never calls a British street absent. Great Britain has no open register of buildings, so a listed road never means a building on it exists.

Common questions about W5

What does a W5 postcode tell you?

That the address lies in the W5 district of the W (West London) postcode area, and the place OS Open Names most often lists first for its postcodes is Ealing. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,007 live postcodes.
