Would you like to know who called you?

This is how tellows works

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, 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 is geared specifically towards those residing in North America. Want to hear more? We have some light reading material that might be of interest to you. Check out our tellows blog for news on the latest scams, tellows products and updates in telecoms regulations that affect you or grab a copy of our free tellows magazine,which came together after our many years of experience on the subject of telephone terror and scams. This not only includes important background information about phone fraud but the methodology behind it.

  3. netzen reported Collection Bureau with the number 8556910192 as Unknown

    Robocall. "Please hold for an important business call". Lady asks for (redacted name), refuses to identify company calling. I suspect this is a debt collection call, but nobody at my number has any deliquent debts, and certainly (redacted name) has none. Caller ID comes up as "800 Service" or "Collection Bureau". also uses 855-691-0193

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.

    This is a trap. A guy called me this morning from this number tell me my computer was hacked. He wanted me to follow his instructions to change my computer setting. I hung up on him immediately. Obviously, he (or this company) is trying to hack and steal information from my computer.

    This guy calls me out of the blue and leaves a threatening message on my voicemail about me needing an attorney and to call him back and if I don't they are going to take "further action" against me. Yeah, okay buddy. I know the name you gave isn't even your real name "Jason" and I could barely understand you due to your foreign accent. This isn't my first rodeo and I know a scam when I see (or hear) one
