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.

  4. Jaclyn reported Jessica with the number 5052967356 as Harassment calls

    Told her to take me off their call list, she asked why, and I just said "Because I said so? Take me off your list." She said "" and hung up! Probably one of the worst scam calls I've had lately. She barely even tried :(

  5. Fletch reported Chase Bank with the number 8004549078 as trustworthy number

    This is the chase bank fraud department. If they’re asking you to call this number it’s because they detected possible fraudulent activity on your account. It’s absolutely legit.

  2. Guy reported Taylor McKenzie with the number +81398225473 as Cost trap

    They claim to be a brokerage and advice you to invest in some legit stock. They sound very convincing and professional. However, from what I could serach for it's a scam. When asked them for bank details they send me a bank on Indonesia. When I refused, send details of another company that reports of being a scam.

    Same company different different numbers constantly phoning me for weeks. Several times a day. I block the numbers so it goes direct to my answering machine. They are filling my machine with recordings making me miss important callers.

  5. Spam Resistant reported Police with the number 6315997199 as Harassment calls

    Called my cell; I couldn't answer while driving. I called back, advised I was returning call I received. Lady asked if the call came to my home or cell. Once they got the answer, they hung up. But they left a recorded message indicating I had 4 criminal allegations against me and to call them at the number they provided, which was the same number in my caller ID. I call them again for kicks but they hung up after answering.
