    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.
    Used by over 200,000 people daily, tellows provides its services to people in over 47 countries, but tellows.com is geared specifically towards those residing in North America. Want to hear more?

    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.

    1. erheaume reported Emergancy communications with the number 8664195000 as trustworthy number

      message de la ville de Brossard

    2. Kay Argie-Bea reported Champion Strategy Holdings with the number 8556236065 as SMS spam

      Text message regarding attempts to contact me but this is the first I’m hearing of it. Called the number back from a masked number and they are a predatory third tier debt collection agency who obviously bought a list of already settled debt and are trying to trick people into paying again. These companies are truly despicable, trying to make money off of scaring people at the lowest socioeconomic rung. Pathetic.

    3. Kay reported Emily with the number 2029320048 as Telemarketer

      Definitely a scam. Called me from 1-860-753-1810 , a number in Perham, CT , but then asked me to call back this number 202-932-0048 on a “first come, first serve” basis which is weird because if I did qualify for student loan forgiveness, why would I have to rush to fill out my application? Emily Myers , agent 3941 from an unnamed company, said her validation code is 061120 — but I would not bother calling back and using that code. Seems suspicious to me.
