How TrueCaller works ?

Many times my friends ask me how this True caller works, from where it get it’s database. So i searched lot and come to conclusion that when some one install this TrueCaller app on their mobile, it scan or sync all contacts from your mobile and make it’s list in their database. That’s How they have created a huge library of phone number with its owner information.

Now when someone calls you, it search for the number in its database and fetch its information if available and displays it on your screen.

You must have observed that it displays random name that someone has saved in their contact. Like one my friend called from his another number that was not in my contact list. So on my screen it displays “Neighbor Boss” but his name is Nitesh, so its clear that it fetches information from other contact list.

And one did not need to have Smart phone or True Caller app on your Mobile Phone to be on True Caller. Your number can be there on TrueCaller Database even if you have not added it, or even you don’t have True Caller App in your Phone.

Actually when some of your friend with True Caller app in his/her phone saves your Contact Number, True caller sync that with its database and list your number in their database. That’s how your number got listed in True Caller.

  1. My husband was at the bar more and more often, so I looked up the numbers in his phone. I was pretty sure he was up to something, or hiding a second phone number app. I am still confused. A new msisdn was added to our tmobile account in July. Does that mean anything? I only got him to admit to contacting one girl he was flirting with at the bar. All of his friends numbers change whom they are listed to, and the numbers change whom they are assigned to when I look it up again. Yes, I am the crazy wife. I only expect honesty from him and he can do whatever he wants to make his life happy (if he wears a condom). I understand men. I want the truth and I can accept anything, as long as we are best friends. I want him to have a life that’s fullfilling and fun. I want a divorce if he is going to keep hiding things. It’s making me nuts.
    Thank you for any information on the situation. I am not computer savvy.

  2. If multiple people with truecaller save a number under different names then how would true caller decide which name to display?
