Carrier Identification Code (CIC)

Carrier Identification Codes (CICs) are used to route and bill calls in the Public Switched Telephone Network (PSTN). CICs are four-digit codes in the format XXXX, where X is any digit from 0 through 9. Separate CIC pools are maintained for Feature Group B (line side) access and Feature Group D (trunk side) access.



How Bandwidth is Involved with CIC

Bandwidth uses CIC codes to route toll free calls to our customers.


What Are the Benefits of CIC

Bandwidth is a RespOrg with multiple service partners which gives us the ability to not only route calls based on quality and cost, but also quickly reroute traffic in the unlikely event of a service impairment.
