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.

      5/11/24, 4:23 PM

      This was a live return call from the Florida telemarketer who used his own number. He asked if this was Tom, and I was caught off guard before I realized he was stating a fake name that I had given other telemarketers. By the time I tried to correct myself he hung up. This same call group has called 516 times since 08/11/2023 and another 105 robocalls for the wireless alarm systems - Core Home Security/Smart Home Security, in which I have recorded proof it was Ryan Neill’s Boca Raton company. He then tried to bribe me with $1500 if I released him of any blame on the robocall that also forged the caller ID. I refused the bribe. I keep detailed logs of all the calls and have many recorded, including the attempted bribe. This # is already on spam lists for financial spams, vehicle warranty calls, & the “Hello, can you hear me?” scam calls. This is a traceable number as when I called back the same guy who called me answered. I then sent him a text stating we was being reported.

    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.

      4/17/24, 2:12 AM

      I keep getting calls from this number. The guys says I showed an interest in Green Card, and said that I qualify to apply. Was a long story about how if I pay a lot of money, they can help me get one. Hmm seemed like a scam for sure.
