How can you recognize an unknown number that is calling you for free?
The free trick: Use an identification app

You don't need to be a cybersecurity expert to regain control. Apps like Truecaller or Hiya are your everyday allies. They function similarly to modern community directories: every user contributes to a shared database. So, if a number is identified as spam, you'll be notified immediately.
Truecaller: Your digital shield
Truecaller is a benchmark in this field, allowing you to see the identity of an unknown caller, block unwanted calls, and even report fraudulent numbers. The basic version of the application is free, making it accessible to everyone. Thanks to its database of millions of users, the risk of fraud is significantly reduced.
