Getting frequent unnecessary phone calls from any number can be annoying. It can become a pain especially if you do not have the idea of who is calling as the number or name of the caller is not displayed. These numbers might appear on your screen as a blocked number, private number, no caller id, or unknown. Such calls can make you sceptical and hesitant to reply to the call or even call back. You might be in confusion whether it is an important call or some spam or telemarketer’s call. This article will throw light on how a hidden call works and how to track private calls to reveal private numbers. How does a hidden call work? Making a call using a private number is not prohibited by any law. However, people don’t usually welcome such calls pleasantly. A private number gives the user the freedom to give their identity to the person they want to talk to. Several codes are used to hide a number and information registered to that number. For instance, *67 and #30#. Once you use these codes before the phone number and make a call, your recipient will see either a private number or an unknown number. You can also unmask an unknown call using such simple codes. Once you have received an unknown call, dial *#30# after receiving the call. The hidden identity of the caller will be revealed immediately. However, these codes differ according to the region you stay in. Hence, we suggest you search for the unmaking code of your region and then make a call. NOTE: Before you try this out, we would like to tell you that these may or may not work for you. As it very much depends on whether your mobile operator allows it or not. Moreover, sometimes calling back to the private number may indicate to them that your number is active. This might lead to sharing your number with various telemarketers and scammers. If you are hesitant to make a call and want to know the identity before you make a call. Then, you can make use of a software application. There are plenty of them available for download and some of them are even free to use.
