GU20 postcode district

Postcodes and sectors

159 of the district's 291 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 51.36484, -0.65001, which locates the district, not a building.

Roads filed under GU20

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 GU20

What does a GU20 postcode tell you?

That the address lies in the GU20 district of the GU (Guildford) postcode area, and the place OS Open Names most often lists first for its postcodes is Windlesham. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 159 live postcodes.

What each figure means, and what a district page never says, is set out in Reading a British postcode district page; the glossary defines a postcode district, a postcode area, a postcode directory and a street register.
