Default Re: The space in the STD codes

As a matter of interest the STD director codes, apart from 01 for London, were in alphabetical order for Birmingham, Edinburgh, Glasgow, Liverpool and Manchester as 021, 031, 041, 051 and 061 respectively.The initial city letters correspond to the numeral on an alpha-numeric dial.

They would be followed by a local 3 digit code often derived from the name of the local exchange in a similar way from a dial. Example 0161-624 2211 for Manchester, Main (Oldham); MAI being represented as 624

Then the 4 digit "subscriber's" number - many of you will know the significance of 2211.
