KT3 postcode district

Postcodes and sectors

Roads filed under KT3

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 KT3

What does a KT3 postcode tell you?

That the address lies in the KT3 district of the KT (Kingston upon Thames) postcode area, and the place OS Open Names most often lists first for its postcodes is New Malden. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 753 live postcodes.
