G12 postcode district

Postcodes and sectors

658 of the district's 959 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 55.88056, -4.30059, which locates the district, not a building.

Roads filed under G12

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 G12

What does a G12 postcode tell you?

That the address lies in the G12 district of the G (Glasgow) postcode area, and the place OS Open Names most often lists first for its postcodes is Glasgow. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 658 live postcodes.
