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.

    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. Nolen S reported CRA collectors (scam) with the number ‎8888638657 as Harassment calls

      4/20/24, 8:44 AM via Android App

      Con artists; I questioned the man, pointing out that CRA has access to more personal information about me than my family does. He called me, so it must be fairly stupid of him to ask for information he should have known previously. Said he wanted to be sure it was me. Inform them to mail anything in an envelope.
