Today, with the prevalence of wireless and VoIP phones, hundreds of local/long distance carriers, consolidations, mergers, and the like, the map has become much more fragmented. Since there were relatively few carriers at the time, it was easy to find Caller ID information and relay it. When Caller ID was developed, the world was primarily a realm of Plain Old Telephone Service (POTS) lines, and the caller information came through the Central Office switch to which the wires were connected. Then, with the caller's number, the callee's service provider is responsible for looking up the caller's subscriber name. When a call is made, the originating phone switch sends the caller's number. The name of the calling party is actually provided by a caller name delivery service known as CNAM. Technically, Caller ID only supplies the phone number of the calling party, but the term has become synonymous with the caller name ID.

What Is Caller ID?Ĭaller ID provides the name and number of a calling party, if available. To help you navigate some common issues related to caller ID, we put together some of the most frequently asked questions and answers on the subject. You're missing out even if you lose just one customer due to something so simple. Inaccurate or missing caller ID information can preclude people from answering your calls. Oftentimes, it's one of the first pieces of information you present to a potential customer, partner, or affiliate. If your business does not have caller ID set up, it's a good idea to talk to your phone company. Rather, the service is essentially a patched-together network of decentralized databases that frequently operate with outdated information. However, unlike local number portability (LNP), caller ID is not regulated by a governing body such as the Federal Communications Commission (FCC). It's offered by just about every commercial phone provider, including landline, VoIP, and mobile phone services. But for the most part, caller ID is a valuable piece of information. The feature isn't perfect, and it can sometimes misrepresent a caller's identity. Caller ID is a widely used phone system feature that identifies an incoming caller by name and phone number.
