SM6 postcode district

Postcodes and sectors

Roads filed under SM6

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 SM6

What does an SM6 postcode tell you?

That the address lies in the SM6 district of the SM (Sutton) postcode area, and the place OS Open Names most often lists first for its postcodes is Wallington. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 756 live postcodes.
