How to Call From an Unknown Number?

Every time we place a call, the Caller ID reveals our identity, isn’t it? Well, it does; at least our phone number and name get revealed through it. However, there are times when you just wish to have private calls with your caller ID hidden. If this is one such time and you are here ensuring that the number you are calling just sees an unknown number calling on their screen, we are here for you. Also, if you’re interested in enhancing your mobile experience, learning how to manage your WiFi password can be incredibly helpful.

In this article, you will be able to have a few ways which will help you to make a call from unknown number to anyone you want. All you will be required to do is follow a few steps, and there it is, a caller ID-free option. Just make sure to do exactly as asked in the steps, and you will be good to go.

Using *67 to Hide Phone Number

It is one of the easiest ways for hiding the phone number. With this method, you will be able to block the phone number in a manner that the recipient of the call would just see the message- Private. They will not be able to see the number or name of the incoming calls.

The technique is very helpful and applies to the call you will place currently. It means unless until you dial *67 in the specific call, for making it private, the default phone number will only be visible.

Note: One benefit of using *67 is that it is helpful both in the case of landlines and mobile numbers.

In order to use this method, Use the prefix *67 (*31 in the case of some American mobile numbers and 141 in the case of UK numbers and landlines) and then enter the 10-digit phone number, i.e., *678963*****5.

Then press the Dial button. With this simple addition, the recipient would see on their phone screen either Blocked, Caller ID Unavailable, Restricted or Unknown Number Calling.

  • Google Voice- allows the new number for making voice calls, and sending audio messages as well as texts, completely free. All one needs to do is have an active Google account for it. This mode is completely free to use as it uses the phone minutes and the data that you already have. However, the number that the recipient would see will be the Google number you will be using.
  • Hushed- this is not a free app, but is definitely cheaper in comparison to the competitors. It charges $2 per week and allows the user to have 20 call minutes and 60 texts. If you want, you can even buy a $5 unlimited monthly plan; the subscription of it can be cancelled anytime.
