Latest from our blog



    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. In response to this universal problem, tellows functions as an online database of telephone numbers associated with spam and scam activity reported by you, our users. By sharing your experiences with unknown numbers, you'll be providing vital warning information to other users unsure about whether or not to trust a certain caller. The more information is shared, the bigger the database grows and thus the chance of finding out who's at the end of that anonymous call becomes higher and higher. Thanks to the tellows app you can identify unknown callers on your iPhone and Android! Whilst you are at it, take a look at our various other useful tools in our tellows shop today.
    Here at tellows.com, not only can we provide up-to-date information on regional nuisance-call trends and currently active numbers with the heatmap, we also pinpoint the origin of your call and display it on a map by identifying the prefix.

      Same overseas telemarketer cold call group who has now called 541 times since 08/11/23 using different numbers (I keep a full record w/dates & times, many calls also recorded w/some even posted on YouTube. They screen the calls then xfer to US companies, of which I have exposed three: One Digital (312-756-8874) Clear Link (801-424-0018) & AJT Diabetic (888-391-3341).
      This was the fake “Healthcare Services” call, where they pose as Medicare saying my old card was expired & a new one was being shipped. She then asked for my existing card number. I said the call was being recorded (it was) & that no one here is of Medicare age & to stop calling. She just hung up. They often call posing as a cable company, Medicare & other Govt offices, banks (fake fraud dept scam), or selling health insurance, car warranties, solar panels, accident claims, loan scams, free internet deals, DNA swab tests etc. They have been told to stop calling 100’s of times, including this call, but they don’t care. Call recorded. My phone service already had this flagged as spam.

    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.
