G20 postcode district

Postcodes and sectors

746 of the district's 1,257 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 55.88590, -4.28248, which locates the district, not a building.

Companies registered in G20

Companies House lists 1,297 companies with a registered office in G20; 279 of them at addresses shared by 25 or more companies (1 October 2026 snapshot). 25 is the count at which the address lookup reports a company cluster.

Roads filed under G20

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 G20

What does a G20 postcode tell you?

That the address lies in the G20 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 746 live postcodes.
