The ability to transmit one’s telephone number during a call can be suppressed, preventing the recipient’s Caller ID display from showing the calling party’s number. This function gives individuals control over their privacy when initiating phone calls. The implementation varies based on the specific phone service provider and device being used.
Controlling the visibility of one’s phone number offers significant benefits, including enhanced privacy and the ability to manage unwanted return calls. Historically, the evolution of Caller ID technology has been met with countermeasures aimed at protecting individual control over personal information. This capability allows users to selectively reveal their contact information only when deemed necessary.
