List of telephone exchanges in London
From Infogalactic: the planetary knowledge core
This is a list of telephone exchanges located within Greater London.[1]
Occasionally in areas of high demand two exchanges are located at the same premises, for example Canary Wharf and Poplar.
NOTE: The United Kingdom adopts an open dialling plan for area codes within its public switched telephone network. Therefore, all area codes have a preceding 0 (zero) when dialling from within the United Kingdom. When dialling an UK number from abroad, the zero should not be included.

Automatic exchanges
London manual exchanges were gradually converted to Director automatic exchanges from 1927. Holborn was the first, at midnight on Saturday 12 November, a local and tandem exchange. Bishopgate and Sloane exchanges followed in six weeks, then Western and Monument exchanges. The London area contained 80 exchanges, and full conversion was to take many years.[3]
