What is a restricted phone call?

A restricted phone call is one in which the caller has blocked their caller ID from being displayed on the recipient's phone. This can be done for privacy reasons, security concerns, or simply to remain anonymous. Restricted calls are often made by telemarketers, scammers, or individuals who wish to keep their identity hidden.

However, some legitimate reasons for making a restricted call include protecting one's privacy when reaching out to an unknown number or contacting someone who may not want their number to be saved.

In some cases, phone carriers may offer services that allow users to block restricted calls or to automatically reject them. Additionally, some smartphone apps can help identify and block unwanted restricted calls.
