We categorise calls by type (debt collection, serious number, sweepstakes, etc.) and give the number in question a tellows score, which indicates whether a number is trustworthy or suspicious, helping you to decide whether or not to take the call.


Latest from our blog



    We've all had to deal with the same thing. Your phone is ringing and the display shows an unknown number you haven't seen before. So you're asking yourself whether to answer it or not!? Who is calling? You are certainly not the first one to ask these questions. For this reason, tellows developed a database which will help you with your decision about answering or ignoring the phone call. This will definitely save you time and energy. Yet, there is more to it. In addition to a risk rating, tellows provides an approximate location of the number calling. This helps you to find out the origin of the phone call.

      They trying to be casual, yet they try to get personal info at the same time. They knew my name and used English, even though they called from Austria at my Polish number.

    Where does the information on telephone numbers come from?

    The tellows community allows you to comment any telephone number. We analyze and classify the calls according to the type of call. The core of tellows is the so-called tellows score. A thought-out algorithm that classifies any number in relation to its risk level. This in turn makes it easier for you to decide whether it is safe to answer the call or not. In order to gather as much information as possible about all the numbers in question, we need your help! With the help of your comments about the numbers and your risk rating you certainly help us to enrich our phone number database.
