About our free web caller ID service

phone image Caller ID goes by different names, such as CID, calling line identification (CLID), calling number delivery (CND), calling number identification (CNID) or calling line identification presentation (CLIP). It is a service provided by the telephone company, and works with older analog phone systems and most new voice over Internet Protocol (VoIP) systems. It simply transmits a caller's number to the called party's telephone equipment during the ringing signal, or when the call is being set up but before the call is answered. When available, caller ID also provides a name associated with the calling telephone number. The information made available to the called party may be displayed on a telephone's display, or a separately attached device. Until was developed, to view this information you needed a Caller ID receiver, a compatible phone, and a subscription to Caller ID service from your telephone operator. Some telephone operators charge as much as $10 per month for Caller ID. That's no longer necessary - you may now lookup the caller ID after the call by using our free service.

Caller ID is particularly useful to track down or limit the impact of tele-marketers, pranksters, and other nuisance callers.

History of Caller ID

In 1968, Theodore George “Ted” Paraskevakos, while working in Athens, Greece as a communications engineer for SITA, began developing a system to automatically identify a telephone caller to a call recipient. After several attempts and experiments, he developed the method in which the caller's number is transmitted to the called receiver's device. This method was the basis for modern-day Caller ID technology. You may learn more about the full history of caller ID on this wikipedia article.
