SP4 postcode district

Postcodes and sectors

Roads filed under SP4

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 SP4

What does an SP4 postcode tell you?

That the address lies in the SP4 district of the SP (Salisbury) postcode area, and the place OS Open Names most often lists first for its postcodes is Amesbury. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,107 live postcodes.
