What does an LL61 postcode tell you?

That the address lies in the LL61 district of the LL (Llandudno) postcode area, and the place OS Open Names most often lists first for its postcodes is Llanfair Pwllgwyngyll. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 248 live postcodes.

248 of the district's 270 postcodes are live in the ONS Postcode Directory of August 2026. A postcode directory says whether a code is in use, never who is there. The live postcodes centre on 53.19574, -4.26332, which locates the district, not a building.

Roads filed under LL61

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.
