The function that allows a device to display the identity of an incoming caller, based on the information transmitted by the telephone network, is accessed and configured within a mobile device’s operating system. For example, users can typically find options to enable or disable the display of their own outgoing number, or to manage how incoming calls are identified, within the device’s call settings.
Effective management of this function enhances communication security and user control. It allows individuals to screen incoming calls, avoid unwanted interactions, and maintain privacy by controlling the visibility of their own phone number. Its development has progressed alongside telecommunications technology, evolving from basic number display to more advanced systems that can incorporate name information and spam detection features.
