Caller Name (CNAM)

Caller Name (CNAM) is a component of Caller ID. It refers to the caller ID name that is displayed on an incoming phone call. When Bandwidth delivers an inbound phone call, our customers can use an API function called ‘CNAM Lookup’ to input the phone number, and query the caller ID. You can think of it as ‘do it yourself’ caller ID.



How is Bandwidth Involved with CNAM Lookup

Bandwidth makes available an API that acts as a query service for our customers to input a phone number, and return the caller ID.


What are the Benefits of Bandwidth’s CNAM Lookup

Bandwidth makes this available through an easy to use, and fast, REST API.
