Roads filed under B30

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 B30

What does a B30 postcode tell you?

That the address lies in the B30 district of the B (Birmingham) postcode area, and the place OS Open Names most often lists first for its postcodes is Birmingham. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 608 live postcodes.
