Data Values. Since the establishment of the telephone city code is made by the local telephone company of the country to which calls are being made, there may not be a distinct numeric relationship for each city (e.g., Dhaka, Bangladesh and Brussels, Belgium both have a telephone city code of 2). It is suggested that a foreign telephone operator be consulted for specific telephone city codes.
