Roads filed under LL58

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 LL58

What does an LL58 postcode tell you?

That the address lies in the LL58 district of the LL (Llandudno) postcode area, and the place OS Open Names most often lists first for its postcodes is Biwmares. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 192 live postcodes.
