    We've all had to deal with the same thing. Your phone rings 24/7 and shows no sign of stopping, but if ever you should pick up, all you hear is the incessant yabbering of a telemarketer or nothing at all. You're infuriated by the anonymous calls jamming your phone line. Is there some way of finding out who is on the other end? Do you pick up or leave it ringing? Who is calling?
    Sound familiar? There are thousands of people asking the same question every day.

    Where does the information on telephone numbers come from?

    Huge amounts of data are entered into tellows sites worldwide each day - further comments on existing numbers as well as entirely new number profiles from first-time searches - all thanks to our users. User contributions are key to tellows' central function: the tellows score. Each time information on a number is given, the information is put through a complex algorithm to generate a trustworthiness rating, on a scale of 1-9. The respective score is clearly displayed at the top of the profile page for each number, making identifying an unknown caller possible in a matter of seconds and saving you not only time, but the frustration of dealing with annoying sales calls.

    2. SB reported number 43598945895844 as Spam Call

      Ugh. Called my work phone, asked for me by my full name, then hung up when I confirmed it was me. Also didn't answer because of the extra long phone numbers. Weird fact, I use my maiden name as my middle name and he asked for me using my first, maiden and current last name. Very weird. Think accent.
