Need to know how find the owner of a phone number ? Do you want to know who this number belongs to? WhatsApp and Facebook are the best reverse directories available to you free of charge.

They include a functionality that allows you to identify a unknown number. This is the solution I use to resolve my doubts about the owner of a mobile phone number, whether in France or abroad.

And yes, we all know that Facebook can know a lot of things about its users. After incessant requests on their applications, the average user breaks down and gives their phone number to Mark Zuckerberg.

So roughly speaking, a large part of the users give their number to Facebook and the other part uses the WhatsApp application. Therefore, there is a good chance of finding the owner of a telephone number with these two methods.

Facebook Reverse Directory

Facebook may seem like a perfect solution to have a free reverse directory whether for a mobile line, or even sometimes for a landline.

The method is simple. To do this, follow these steps:

  • First, on your PC, phone or tablet, open the Chrome app.
  • Then, to the right of the address bar, tap More. new tab private navigation.
  • A new window appears. Go to the lost facebook account recovery page.
  • Now, enter the phone number of your interlocutor and click on Search.

  • You will see appear in the search result: the name, first name and photo of the person who called you.
  • Then to have more details about this person, you could consult their profile.

Limitations of number search on Facebook

Although Facebook serves as an excellent free reverse directory, it has a notable limitation: the user must voluntarily provide his telephone number. This is not always the case, and the information is not necessarily up to date. Indeed, since Facebook has been around for several years, it is possible that the person has changed their phone number.

We therefore recommend verifying the telephone number listed on Facebook by other means, such as by consulting another telephone directory.

Also, the number listed on Facebook can be a landline or a mobile, and not necessarily the one you are looking for. In this case, we advise you to try another free reverse directory, such as WhatsApp.

WhatsApp Reverse Directory

To find out the owner of a number with WhatsApp, follow these steps:

  • On your phone, open the Contacts app.
  • Tap Add. And enter a random name and phone number.
  • Then open the WhatsApp application.
  • Refresh your WhatsApp contacts.
  • As if by magic, you will see the real name and profile photo of the person you are talking to.

Note that this method only works if the owner of the number uses WhatsApp themselves, but given that the application is now used by a large majority of mobile users, there is a good chance that you will be able to identify it.

Moreover, the opposite is also often true. Indeed, if you have a friend on WhatsApp, the phone number that will be displayed is likely to be the same. However, as you have probably noticed, people are more likely to give their WhatsApp number than their personal telephone number.

To tell you, in this way, you will even be able to recover telephone numbers which have nevertheless asked their telephone operators to be on the red list for example.

Beware of fake numbers on WhatsApp

As we have just said, WhatsApp is now a fairly simple and practical way to get around the various limitations put in place by traditional telephone operators and many people use it.

For the majority of people, you will be able to trust what will be indicated on the screen and it is therefore their real telephone numbers which will be indicated on your screen, which simplifies your task.

However, the number displayed on the screen is not always the correct one. In fact, there are customer services that simply offer to create a virtual phone number to register on WhatsApp.

Therefore, the number displayed on the screen is not the correct one. Here again, what we advise you to do, once you have found the number on WhatsApp, is to check other services like phone directories.
