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.

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. Lottie reported Green Card Lottery with the number +17864542439 as Sweepstakes, lottery

    For years I have seen these adds where you can add some info to see if you are eligeable to participate in the green card lottery. I was curious, even if I don't want to apply, I am NOT interested in moving to the US! When I had entered, I got a reply that I was eligeable and was offered on screen to pay an amount in order to enter the lottery. I of course closed the form at this point. This was during this weekend, today is Monday (although a holiday here).

    First the phone rang once. I let it ring. But then it rang again. I denied it. Then they just kept ringing over and over again. That is harrassment, as I see it! I blocked them!

    Well, if they start calling from different numbers, I will just keep blocking them. Just ringing like they did now, keep repeating, even if someone obviously can't speak at the moment or just are not interested, is just disrespectful and very offputting! Calling like that, e.g. If a person is driving, could cause an accident!

    They are obviously very eager to get hold of your credit card number and some of your money ($39 or smth like that)
