List of telephone exchanges in London
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.
