The Beginning of the 01603 Area Code

Prior to the PhONEday event in April 1995, the area code was 0603 and the historic mnemonic code was NO3, with the first two characters taken from the letters N and O in NOrwich. On an old rotary dial telephone, this code would have been entered by dialling the numbers 6, 0, and 3.
