Carrier Identification Code (CIC)

Carrier Identification Codes (CICs) are four-digit codes (any digit from 0 through 9) used within the Public Switched Telephone Network (PSTN) to route calls.


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.
