Any incoming phone call that doesn’t display any information about the caller or phone number is called a restricted call. In this case, a person wants to keep his number secret and does not want anyone to track his number.

If a person or company is restricting their own phone number so that the person or business they are contacting cannot see the phone number then such technique is referred to as a restricted call.

Normally, whenever we receive a call from someone their phone number is shown on the screen. Also, some third-party apps enable people to see the name of the caller through caller ID. Your phone’s call log will record all this information.

However, a restricted call hides that information from the person you are calling.

When a call is restricted, the caller status changes to anonymous as their information is not going through to the person you are calling. Also, the call will be listed as anonymous in the call log. There is no way that you will be able to see this information.

Restricted calls are becoming more untraceable than ever because of the continuous growth of technology. People have a hard time blocking this call.  

What is a restricted number?

The phone number that has been for making restricted calls is referred to as a restricted number. These numbers are private numbers. The person or business using a restricted number has totally restricted their phone number from the public so that nobody can view the number.

There is no way anyone can find the phone number via caller ID or call log. The only way of knowing the restricted phone number is if the person or company directly gives you the phone number.
