We often receive calls from unknown numbers. Sometimes these are harmless bugs, but they can also come from real scammers who just want to hurt us by inflating our phone bill to get rich behind our backs. Do you want to find the authors of these disturbing calls? It is quite possible thanks to the application that we are going to reveal to you today. It will tell you the exact location of the caller and even the name of the caller or the company they represent.
What is an unknown phone number?
An unknown phone number is a phone number that is not in your contact list or that you do not recognize. It could be a call from someone or a company you don’t know.
There can be several reasons why someone calls with an unknown number. It could be a prospecting or marketing call, or it could be someone you know but has changed their phone number and is not yet in your contact list.
It is recommended not to answer a call from an unknown phone number, especially if you suspect it may be a scam or spam. If you decide to answer anyway, be careful not to give the caller any personal or financial information.

Luckily, some companies always choose the most inopportune moment to make their calls. This is called “phone spam”: it consists of bombarding users with calls from an unknown number. Generally, these companies aim to attract new customers. Except that disturbing them at meal or nap time isn’t necessarily the best marketing strategy.
Many times, thinking that it is an important call, even if you do not recognize the number, you have no choice but to pick up. How frustrating to realize that this is just a business call. It can even be very annoying for some, especially if they were very busy at the time. It’s even more disturbing when, over the phone, the salesperson insists on describing their products to you.
How to protect yourself against this type of nuisance? To identify the origin of calls with an unknown number, we recommend that you download the “Truecaller” application. It’s free, easy to use, and available on iOS and Android. This platform is based on “Crowd Sourcing”, that is, it retrieves your information from the mobiles of those who download it. In other words, copy the entire phone book. After copying the data of the users, currently 500 million people, the application makes them available to you at the moment you receive a call from an unknown number that is not in the memory of your mobile phone.
The main advantage of “Truecaller” is that you will have immediate access to the location and name of the person or company calling you. You can filter all those that do not interest you. Apart from disruptive calls, you will also be able to avoid all the scammers who contact you from abroad to steal your money with premium rate calls.

But by the way, do you know how to call someone anonymously? Sometimes, in certain contexts, you don’t want to show your number for personal reasons or just to hide your contact details. If you want to make a call to a hidden number, you can do it in a very simple way. Just type #31# just before dialing the number.
For users of the Android operating system, there is another nifty method: you can hide your number by going to the settings, specifically the caller ID tab. Here you can activate the option “Hide the number” and it will no longer appear during your calls. Similarly, you can disable this option at any time.
