Caller ID spoofing is a technique used to change the information that appears on a recipient's phone when receiving a call. This can make it look like the call is coming from a different number, often one that appears familiar or trustworthy. People may use this method for various reasons, including telemarketing, scams, or even pranks. While caller ID spoofing can be used for legitimate purposes, such as businesses wanting to display a specific number, it is often associated with fraudulent activities. Scammers may impersonate banks or government agencies to trick individuals into providing personal information, leading to identity theft or financial loss.
