SA46 postcode district

Roads filed under SA46

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 SA46

What does an SA46 postcode tell you?

That the address lies in the SA46 district of the SA (Swansea) postcode area, and the place OS Open Names most often lists first for its postcodes is Aberaeron. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 130 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.
