W10 postcode district

Postcodes and sectors

692 of the district's 1,157 postcodes are live in the ONS Postcode Directory of August 2026. A postcode directory says whether a code is in use, never who is there. The live postcodes centre on 51.52319, -0.21661, which locates the district, not a building.

Roads filed under W10

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 W10

What does a W10 postcode tell you?

That the address lies in the W10 district of the W (West London) postcode area, and the place OS Open Names most often lists first for its postcodes is Kensington. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 692 live postcodes.
