- When accounts are designated by numbers, the synonymous term account number is more common. The term account code is principally used when accounts designators are non-numeric, for example if they use both letters and numbers.
account code - Computer Definition
A code that a user enters via the telephone keypad when placing an outgoing call, particularly a toll call, through a PBX or KTS telephone system to track calling activity and to aid in client billing for time and expenses. Some users may be required to enter an account code, known as a forced account code, in order to place a call. Some systems allow a user to enter an account code for incoming calls, as well.
