Caller ID blocking on Android devices involves methods to prevent a phone number from being displayed to the recipient of a call. This is achieved through phone settings or carrier-specific codes, ensuring the number appears as “Private Number,” “Unknown,” or similar on the receiving device.
Concealing one’s phone number during calls offers increased privacy and control over personal information. It can be useful to avoid unwanted callbacks, protect against potential harassment, or maintain anonymity when contacting businesses or individuals. Historically, this functionality evolved from earlier call-screening technologies, becoming integrated into mobile operating systems as privacy concerns grew.
