Why is there a need to expand CACs from five-digits to seven-digits?
The change in CACs is necessary because the industry exhausted the supply of the three-digit CICs, which are used to form CACs, in 1995. Unless CICs are expanded to four-digits companies will not be able to enter the market because they will not be able to obtain the access code that their customers need to obtain access to the carrier’s services. The expanded CIC format will make approximately 10,000 CICs available for assignment.
