EC4A postcode district

Postcodes and sectors

110 of the district's 515 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 51.51580, -0.10818, which locates the district, not a building.

Roads filed under EC4A

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 EC4A

What does an EC4A postcode tell you?

That the address lies in the EC4A district of the EC (East Central London) postcode area, and the place OS Open Names most often lists first for its postcodes is City of 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 110 live postcodes.
