 City of London Postcode Areas, Districts & Map Guide

 Overview of the City of London Postcodes

The City of London (often called the “Square Mile”) is one of the smallest administrative areas in the UK, but it has a very dense and complex postcode structure.

It is mainly covered by:

  • EC postcode area (Eastern Central London) → core City of London
  • Parts of EC1–EC4 districts
  • Small overlaps into WC postcode area (West Central London)

Unlike counties, the City of London does not use many districts—it is instead divided into EC postcode sectors tied to business zones, financial districts, and historic streets.
