How to find out private number, the complete guide

1. How to find out private number for free with TrueCaller

First of all you have to download the TrueCaller application on your mobile. For this we have the official applications in the Play Store on Android as well as on the iOS AppStore. You need to download the application as you would any other mobile device, then run the application to proceed with its configuration.

In the case of Android, when you first go to the initial loading screen and press the Start button, you will see several notifications where the app asks for permissions to view calls, calendar and SMS and you will have to give consent to everything, so that it works properly.

This will only have to be done the first time you use the app, i.e. once reopened, they will no longer bother you with permissions. Once permissions are granted, you will continue to navigate the initial application setup. The second step is to communicate your phone number.

Choose your country in the box above to set the country code, then type in your phone number and press Continue. The application will take a few seconds while making a test call and, once done, it will automatically go to the next screen.

Now, with some screenshots, the application will explain a little about how to find out private numbers and will ask you to replace the shortcuts to make calls with TrueCaller. Go and press Next until you have read all the information and voila, you have finished the initial setup process. You don't need to use the TrueCaller app to send calls or manage SMS, so it's up to you to decide whether to use it.

Also, keep in mind that TrueCaller will always be running in the background, so your phone's battery drain and RAM memory may suffer a little. However, there shouldn't be any overly noticeable changes.

From now on, whenever someone who is not on your agenda calls you, Truecaller shows you who the number belongs to. It works with both hidden and private numbers and for calls from companies you don't know.

And when you end a call, the application will allow you to call that person again, save their number in the phonebook or block it so they can't call you again. It also allows you to tag the person who called you in case you want to indicate that they are an employee of company X or Y.
