The unauthorized masking of a caller’s true telephone number with a different, often fabricated, number is a deceptive practice. This allows the perpetrator to disguise their identity, making it appear as though the call is originating from a trusted source, such as a neighbor, a local business, or even the victim’s own number. For example, an individual receiving a call that displays their own phone number as the caller ID is likely experiencing this manipulation.
This manipulation erodes trust in caller identification and can facilitate fraudulent activities. The ability to impersonate legitimate entities enables scammers to extract personal information, financial details, or even distribute malware. Historically, such techniques were limited due to technological barriers; however, advancements in VoIP technology have made this type of deception significantly more accessible and widespread, creating a growing challenge for consumers and telecommunications providers.
