Roads filed under SN25

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 SN25

What does an SN25 postcode tell you?

That the address lies in the SN25 district of the SN (Swindon) postcode area, and the place OS Open Names most often lists first for its postcodes is Swindon. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 821 live postcodes.
