Roads filed under NN11

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.

That the address lies in the NN11 district of the NN (Northampton) postcode area, and the place OS Open Names most often lists first for its postcodes is Daventry.
