SA70 postcode district

Postcodes and sectors

Roads filed under SA70

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 SA70

What does an SA70 postcode tell you?

That the address lies in the SA70 district of the SA (Swansea) postcode area, and the place OS Open Names most often lists first for its postcodes is Dinbych-y-Pysgod. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 425 live postcodes.
