CNAM (Caller Name Identification)

CNAM (Caller Name Identification) is a service that displays the name of the person or business calling you when your phone rings. It works by matching the caller's phone number to a database that contains names associated with those numbers. When a call is received, your phone or service provider retrieves and shows the caller's registered name on your screen, helping you identify who’s calling before answering. This service enhances call awareness and can help you decide whether to answer or ignore a call.
