SE6 postcode district

Postcodes and sectors

Roads filed under SE6

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 SE6

What does an SE6 postcode tell you?

That the address lies in the SE6 district of the SE (South East London) postcode area, and the place OS Open Names most often lists first for its postcodes is Catford. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 863 live postcodes.
