The G postcode area, also known as the Glasgow postcode area, is a group of postcode districts in central Scotland, within six post towns. These districts are primarily centered on Glasgow itself, and West Dunbartonshire (including Dumbarton, Clydebank and Alexandria), plus parts of the council areas of Argyll and Bute (including Arrochar and Helensburgh), East Dunbartonshire, North Lanarkshire, South Lanarkshire, East Renfrewshire and Stirling.

Former postal districts and their legacy

From 1923 until the introduction of the national postcode system in the late 1960s, Glasgow was divided into (mostly) numbered postal districts for its central and surrounding parts identified by compass-point letters: C1–C5 (corresponding to current postcode districts G1–G5), W1–W5 (G11–G15), NW (G20), N1–N3 (G21–G23), E1–E4 (G31–G34), SE (G40), S1–S6 (G41–G46) and SW1–SW3 (G51–G53).
