E3 postcode district

Postcodes and sectors

1,176 of the district's 1,633 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 51.52810, -0.02483, which locates the district, not a building.

Roads filed under E3

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 E3

What does an E3 postcode tell you?

That the address lies in the E3 district of the E (East London) postcode area, and the place OS Open Names most often lists first for its postcodes is London. The district alone does not place a street: the inward half of the full postcode narrows the address to one of the district's 1,176 live postcodes.
