How Caller ID Works: The Complete Guide to Identifying Unknown Numbers

What Is Caller ID?

Caller ID is a telephone service that transmits the calling party's number and sometimes their name to the called party's device before the call is answered. This technology has evolved significantly since its introduction in the 1980s.

How Modern Caller ID Works

Traditional caller ID relies on CNAM (Calling Name) databases maintained by telephone companies. When you receive a call, your carrier looks up the calling number in these databases and displays the associated name. However, this system has limitations - it does not cover mobile numbers well and can be spoofed.
