Frequently Asked Questions


What is CNAM?

CNAM, which is short for Caller ID Name, refers to the name of the person or business placing a phone call. CNAM data allows phones to display the caller’s name, in addition to the caller’s phone number. This is sometimes also referred to as Caller ID Name or caller name.

Telephone carriers often populate one of several authoritative databases with subscriber data. These databases are known as CNAM repositories. There are many services that offer name data for phone numbers, but CNAM specifically refers to data retrieved from these official carrier-supplied sources. The values are a string of text no longer than 15 characters, which is ideal for displaying on all telephone devices that support CNAM.
