SW1E postcode district

Postcodes and sectors

87 of the district's 375 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 51.49809, -0.13980, which locates the district, not a building.

Roads filed under SW1E

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 SW1E

What does an SW1E postcode tell you?

That the address lies in the SW1E district of the SW (South West London) postcode area, and the place OS Open Names most often lists first for its postcodes is City of Westminster. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 87 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.
