What is the Caller ID?

Caller ID is a phone feature that displays the name and phone number of a party that is calling, if there is one. While Caller ID provides the number of the caller's phone, its use as a name has made it synonymous with the name of the caller. The name of the calling party is actually supplied by a service called CNAM.

How Does Caller ID Work?

The phone switch that originated the call will send the caller's number to the person calling when calls are made. The caller's phone number is transmitted to the original telephone switch. This lets the service provider search for the subscriber's name.

At the time it was created in the early days, the world was mostly a realm of Plain Old Telephone Service (POTS) lines. In addition, the caller's details were tied to the Central Office switch to which the wires were connected. Given that there were small number of carriers at the time, it was easy to manage the caller ID details all in one place.

With the advent of both wireless and VoIP phones, hundreds of local/long distance providers, consolidations, mergers, and similar, the map has become much more fragmented. In contrast to phone numbers and domain name service (DNS) in which there are internationally recognized databases which are trusted sources, there is no central authority or regulation of caller ID. No FCC guidelines govern accuracy of carriers as well as, while federal regulations apply to telemarketers as well as spoofing, companies can manage their caller ID databases as they wish.

What Is a CNAM?

CNAM (Calling NAMe) is an outside telecom service that phone companies use to match incoming numbers with names. CNAMs do not have centralized databases, like phone numbers. Each carrier has the option of choosing among a variety of CNAMs. Each CNAM keeps its own private database on phone number/name pairs within the United States and abroad.
