How to know who a Wind SIM card is registered to

Author and references

Preliminary information

Before getting to the heart of the tutorial, it is my duty to make some clarifications regarding the practice object of this guide. Let's start from a fixed point: unlike fixed numbers, for which there is a public telephone directory that allows you to trace the relative holders (for customers who have consented to the thing), for mobile numbers something similar is not available.

For a question entirely related to privacy, in fact, the only ones who can know who the numbers associated with the SIMs are headed to are telephone operators (and the police), who, among other things, cannot communicate this data except directly to the holder (after having carried out the necessary checks).

Based on what has been said, in theory there would be no valid systems to find out who a SIM is registered to, regardless of the telephone company. In practice, however, there are gods on the Net collaborative services, which users can use to voluntarily disseminate information about their telephone numbers and to report those of known annoyances (call centers, telemarketers and scammers) in order to avoid being disturbed by the latter by answering an unwanted call.

These services, therefore, can be used to try to trace the holders of the numbers, if they have explicitly consented to the dissemination of their number online. Obviously, the success of the operation is not guaranteed, given the above conditions, but, as they say, trying is not harmful.

In any case, it should be borne in mind that there may be a clear difference between the holder and real user of the card: the holder is the one who has purchased and activated the card, providing an identity document and his tax code and to whom the card therefore belongs. The real user could be the same holder, but it could also differ, since, once activated, the SIM can be sold to a relative, to one's partner, etc.

Web services to find out who a Wind SIM card is registered to

As I told you, for know to whom a Wind SIM is registered you can rely on one of the various web services of a collaborative nature available on the Net, which, based on the reports provided by users, can offer interesting information regarding a given numbering. To find out what these tools are and how to use them, continue reading: you will find listed below those that, in my opinion, are the best in the category.


Truecaller is a famous website that allows you to identify the numbers of users who have consented to the use of the service and those of known annoyances, based on a constantly updated data archive. It's free, but to consult the search results you need to log in via your Google or Microsoft account and share your address book (a practice that I do not recommend, even for fairness to other people).

To use it, go to the home page of the service and type the telephone number of your interest in the appropriate field at the top, making sure that the prefix correct (otherwise change it). Next, hit the key with the magnifying glass. If the number you previously entered is included in the Truecaller database, you will be able to know the details about it.

Note that Truecaller is optionally also available as Whatsapp for Android and iOS. It works in a similar way to its online variant but, in this case, in addition to allowing you to receive more information about the numbers, it also allows you to block unwanted calls and SMS. For details regarding the use of the application, I refer you to reading my guide on how to inhibit a call.

Who's calling?

Another service to consider to try to know who a SIM is registered to, regardless of the operator, is Who's calling?: this is an additional collaborative portal that uses user feedback to create a database in which the holders of many mobile (as well as landline) numbers are present. It's free and you don't need to register or share your number to use it.

To use it, go to the Who's calling? Home page. and type the number to be identified in the search bar located at the top, then press the button Wheel. Once this is done, if the number entered is present in the site database, you will be shown a page with all the information relating to it and the comments of the users who have allowed to identify the address.

I also point out that "Who is calling?" is also available as an app for Android and iOS devices, under the name of Should I Answer. It has the same functions as the online variant, but in addition it allows you to block calls and SMS from unwanted numbers. For more information, you can refer to my guide on how to avoid advertising calls.


Believe it or not, too Google, the famous search engine, can prove to be a valid ally in trying to find out who a SIM Wind (or any other operator) is registered to. In fact, looking for the phone number of your interest through Google and consulting the search results, you could find interesting information relating to it through which to infer the holder.

To proceed, go to the Google home page, type the cellphone number of which you want to find out the owner in the field located in the center and press the button Search with Google. Then sift through the search results that may be proposed and open those that you think may contain the details of your interest (for example, if the number holder is a professional and has shared his number on a website or blog).

For further information on the use of the famous Mountain View search engine, I suggest you take a look at my guide dedicated solely to how Google works.

Costumer Services

Another system available to understand who is the holder of a Wind SIM is to contact the customer care operator. In this case, however, you will simply be notified, providing your data, whether you are the real holder of the SIM or not. If you are not, unfortunately, the name of the contact person cannot be indicated.

To do this, take your phone and dial the 155 (Wind's customer service number). When the call has started, listen to the instructions of the recorded voice and press the button to receive support (should be the 2).

Then, if you are calling from home, press the button 1 and insertion il number for which you need help, then press the button to receive the assistance of a consultant (should be the 3) and waits for an answer from an operator, to whom you can explain that you intend to find out whether or not you are the owner of the card. Note that in doing so, you may be asked to provide your own number identity card valid and / or yours fiscal Code, so keep everything close at hand.

Still on the subject of customer service, a clarification must be made: the combinations to be used to get in touch with a Wind operator, as well as those relating to the customer service of any other telephone company, are often subject to change. Therefore, my indications aside, I strongly suggest that you follow the instructions of the guide voice with the utmost precision, in order to avoid form errors and annoying waste of time.

As regards the costs of the service, the call is free for Wind, Tre, Infostrada customers and for those calling from the TIM fixed network. In all other cases, the tariff applied is that relating to the plan subscribed to with the reference telephone operator.

As well as as I have indicated above, you should know that you can get in touch with Wind's assistance also by using the service of social care available on Facebook and Twitter. For further information, refer to my specific guide on how to talk to a Wind operator.

Wind shops

You can understand if you are the real owner of a Wind SIM even by going to one of the shops of the manager present on the national territory and asking the sales clerk for clarification. How you do it? I'll explain it to you right away.

First of all, locate the Wind store closest to you by consulting the appropriate map on the operator's website. So, type in the name of the resort where you are in the search field at the top left, select the suggestion relevant from the list that appears and consult thelist available on the left, to find out where a Wind center is located nearby. Alternatively, look at the indicators on the map and click on the one you are interested in to view its address.

Then, go to the site, explain to the sales person the fact that you want to understand if you are the holder of the SIM Wind that you own or not and wait for the response. Most likely, you will be asked to exhibit a identity card valid and the fiscal Code, then take them with you to be able to provide the necessary data at the appropriate time.
