Concealing the caller ID on outgoing calls made from an Android device prevents the recipient from seeing the caller’s phone number. This can be accomplished through a phone’s settings menu or by using a prefix code before dialing a number. For example, dialing *67 before the intended recipient’s number will typically block caller ID on that specific call.
Maintaining privacy and controlling personal information are key advantages of hiding one’s phone number during a call. In certain situations, such as contacting businesses or individuals for the first time, obscuring the number can reduce the likelihood of unsolicited call-backs or data collection. The ability to block caller ID has been available for many years, initially as a feature offered by telephone service providers and subsequently integrated into mobile operating systems.
