Before 1989, there was one dialling code for London: 01, plain and simple. Admittedly getting particular numbers allocated was a pain, but it was due to overcrowding in the number range that the numbers were split into inner and outer London.

History
Before 1989, there was one dialling code for London: 01, with seven-digit local number, plain and simple. Admittedly getting particular numbers allocated was a pain, but it was due to overcrowding in the number range that the numbers were split into inner and outer London. (See the page Locale Docklands for a reference to this.)
From 1989, the dialling codes changed FOUR times:
Date | Code | Notes |
---|---|---|
Up to 1989 | 01 | |
1989 to 1992 | 071 and 081 | London was split to 'inner' and 'outer' areas. |
1992 to 1999 | 0171 and 0181 | National codes were all changed to add a '1' after the initial 0. |
June 1999 to April 2000 | 020 with 7 or 8. | Introductory period - the previous dialling codes continued to work. Local numbers were still dialled as 7 digits, e.g. 123 4567 |
2000 to present | 020 | All London numbers have an eight-digit local number. |
In 1999, the exchange codes (the four digits immediately after the 020) were properly reorganised to be 4 digits long, with the whole local number 8 digits long. It is no longer possible to determine the location of a subscriber within London based on the area code.
It can be a good indicator of how long a firm has been in business if it has a sign using one of the older dialling code conventions (and also of how much they care about their frontage).
