History of the 01223 area code

Cambridge was one of several areas to originally be issued with two area codes. When dialling in from outside the Cambridge area, the area code 0223 was used for a central 'core' area, while a second 0220 'ring' code was used for accessing a few telephone exchanges in outer areas.

The length of local phone numbers could vary between individual exchanges and dialling between local telephone exchanges wholly within the Cambridge area used a relatively complicated system of short codes starting with 8 or 9.

By the end of the 1980s, the system had been greatly simplified. Six-digit local numbers became the norm and the telephone exchanges that had previously used the 0220 area code had all their numbers absorbed into the main 0223 area code.

The next significant change occurred in 1995, when the 0223 area code was changed to 01223 as part of a nationwide renumbering programme. No further changes have taken place in the area.
