Answering calls from incognito and anonymous people whose data is not in the phone book is not a good idea for any subscriber. Most people avoid communication with marketers who try to sell another piece of junk at a discount. They reject an incoming call if they don’t see a familiar number.


Irritation can be avoided even before answering the call. Each subscriber has at least 3 ways to check who owns the phone number and block incoming calls proactively. It is about the use of public registries, closed databases and even mobile applications.

Search systems

The easiest way to determine the owner of the number is to enter the data into any search engine (for example, Google, Bing, Yahoo). Based on the results of the issue, it is easy to draw conclusions and clarify from whom the call came: an individual or a representative of the call center. Current information is available in public registers, websites about fraudsters and even on forums. Access to some sites is provided after registration.

Forum participants describe in detail possible schemes of deception. If not only the phone, but also part of the personal data was transferred to the alleged representative of the company, it is better to look at the screenshots and read some detailed comments. This is the best way to understand the possible consequences.

Websites that identify numbers

An alternative to typing the number from which the call came into global search engines is to use special registers. On such platforms, content is created directly by Internet users. Ordinary subscribers visiting such online resources can find a phone number in the database and find out who called (fraudster, marketer or ordinary citizen). Here are the advantages of such platforms:

  • you can quickly determine who owns the phone number and share your experience;
  • in most cases, data about companies and fraudsters is available without registration;
  • only authorized users are allowed to add information about spammers or spammers.

Teams that have created public registries encourage comments and allow authorization through Facebook. But it does not work on every resource. If the function is provided, people do not hesitate to tell what they talked about with managers or fraudsters, how exactly the conversation went, and answers to which questions are better to avoid.

Social networks

Free identification of subscribers is possible through social publics of open and closed type. Those who want to protect themselves from dishonest methods of intercepting bank card passwords can find useful comments on such pages. Not only with screenshots, but also with audio or video files.

Community members willingly expose call center employees and help protect against repeated contact with ill-wishers. Although not everything is so perfect with this method. Due to the rules of the platform, Facebook users do not have the opportunity to quickly find people by entering a phone number. The internal search engine has disabled this feature since 2020.

Before you find out about an unknown number, you will have to go a long way. Internal search does not work even with contacts of people who are among the friends of a particular user. That is why detecting fraudsters will be routine, which consists in visiting publics and viewing dozens of comments. This means that it is better to find an alternative service.
