What is CNAM lookup?

CNAM, or caller ID name, is a feature in the US public telephone network that associates business and personal phone numbers with names. The carrier from whom a number has been subscribed adds the CNAM information to CNAM repositories that are collectively referred to as the line information database (LIDB). When someone receives a call, their carrier queries the LIDB and displays the assigned caller name.
