Truecaller and your number: how caller ID apps use data.
How caller-ID apps like Truecaller build their directory, what your contacts may have shared about you, and how to manage your number in India.
The simple answer
Caller-ID apps like Truecaller can show a name for an unknown number because someone, somewhere, had that contact saved and the directory learned it. Your number can appear even if you never installed the app.
This is the contact-list effect at scale: when many people upload their address books, a shared directory forms. The privacy question is consent, because you may be listed without ever agreeing.
