KT1 postcode district

Postcodes and sectors

Roads filed under KT1

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 KT1

What does a KT1 postcode tell you?

That the address lies in the KT1 district of the KT (Kingston upon Thames) postcode area, and the place OS Open Names most often lists first for its postcodes is Kingston upon Thames. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 687 live postcodes.

What each figure means, and what a district page never says, is set out in Reading a British postcode district page; the glossary defines a postcode district, a postcode area, a postcode directory and a street register.
