How to find the holder of the mobile number

Did you find a phone number written on an old post-it stored in your desk drawer that you can’t remember who the owner is? Are you receiving fairly frequent calls from an unknown address and would like to find out who it belongs to? Maybe I can help you out. Or rather, they can give you the solutions to find the holder number that I am about to recommend.

Finding out who owns a cell phone number, I tell you right away, is not easy, since as you know there are no public lists for the latter … but we must not despair! There are, in fact, services in which users voluntarily share their telephone numbers, in order to make them publicly traceable: try them and with a bit of luck you will succeed in your intent. Again in this regard, it could be very convenient to rely on the “power” of instant messaging services, social networks and the Internet in general.

The situation becomes much less complex when you try to trace the holder of a landline number: just turn to public directories or collaborative identification services, which use user comments to “track down” telemarketing operators, the scammers and all those annoyances who annoy us every day with their phone calls. It usually takes only a few seconds to get all the information you need. To find out more, read on.

How to find the holder of the mobile number

Let’s start by trying to figure out how to find the mobile number holder . As anticipated at the beginning, there are no public lists for mobile network users, consequently you have to in a certain sense “make do” and cross your fingers so that you can find the holder of the number using collaborative lists, as in the case of those reported below, as well as through messaging services and social networks.


When it comes to mobile phone numbers, among the best solutions available on the market to be able to find the owner number, there is no doubt Truecaller. This is an online service which, drawing on a proprietary database consisting of the numbers of users who have consented to the use of the service, allows you to easily identify telephone numbers not saved in the address book. Basically it is free, but eventually it is possible to subscribe to a paid subscription (at the basic cost of 3.99 euros / month) which allows you to remove advertising and unlock other extra functions. Note, however, that to be used it requires the sharing of your number within its public database, which is not the best for privacy, so I invite you to carefully consider whether to use it or not.

If you decide to try Truecaller, to use it you need to connect to the home page of the service , fill in the Search a phone number search field at the top by entering the mobile number for which you want to get more details and click on the button with the  magnifying glass . If necessary, before starting the search, change the prefix using the appropriate menu on the left, selecting the correct option from it (eg +39 Italy ).

After completing the above steps, decide whether to log in to the service using the Google account or the Microsoft account by clicking on the relevant button that is proposed to you on the screen and providing your data, then wait for the page to be visible with the search results. If you are asked to share your address book , do not agree.

If the number you previously entered is present in the Truecaller list, you will see a specific card indicating the total number of users who have reported their contact details, the users they belong to and their address. If the numbering is not present in the Truecaller database, you will be immediately notified on the screen.

If you are interested, I would like to point out that Truecaller can also be used in the form of an app for Android mobile devices (also available on alternative stores ) and iOS .


Another service that in my opinion you would do well to consider if you are interested in finding a free mobile number holder is  Tellows . If you have never heard of it, I inform you that it is an additional collaborative portal that allows you to identify numbers from the so-called “known annoyances” thanks to the feedback and reports of other users. It is totally free and requires no registration.

To use it, go to the relevant home page and type the phone number of your interest in the text field enter the number located both in the center of the page and at the top right, then start the search by pressing the button with the magnifying glass adjacent magnification .

If information is available for the phone number you entered previously, you will be shown all the details of the case in the new web page that will open. If, on the other hand, the number is not present in the service lists, the search will return no results.


To try to find the owner number, the use of WhatsApp can also be very useful . If the reference telephone number refers to a WhatsApp account, in fact, it will be possible to view the relative user name and, consequently, to trace the holder of the line, provided that he has used his real data and that he is the actual user. of users.

That said, in order to use WhatsApp for your purpose, all you have to do is take note of the mobile number of your interest and add it to the phone book , following the procedure provided for the mobile platform in use: in general, anyway , just open the Contacts app and press the button to add a new name .

After completing the steps above, open WhatsApp, start a new conversation by pressing the icon of the comic and checks whether the name previously saved appear in the list of available contacts. If so, tap on his profile picture , in order to view the details of the user profile and, therefore, also his name.
