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 rattles furiously as it's bombarded with nuisance call after nuisance call and you have no way of knowing who's calling. Will it be over enthused telemarketers or, perhaps even more annoying, a swift click and the dialing-tone drone? Should you take the call or ignore it? Who's on the other end?
Rest assured that you're not alone. In a world where cold callers can sometimes seem to hold a global monopoly over phone lines, tellows aims to provide a solution. We function as a vast online database of phone number profiles, generated thanks to feedback and reviews from our online community. Providing an online platform where users can share their experiences of these kinds of calls and flag up numbers responsible for junk calls means that information on suspicious numbers becomes readily available, helping other members of the tellows community to anticipate potential risk calls. Join the international community that is currently operating in 47 countries with more than 200,000 users on a daily basis and download the new tellows app today for your iPhone or android. And whilst you are at it, take a look at our various other useful tools available for purchase in our tellows shop.
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.
We ontop feature the pinpoint location your call originated from and display it on a map, using the dialling code. Learn more about international dialling codes.

    Today I had the same experience, via Skype, with English names that had Indian accent, claiming to be recruiters from Corporate-staff. None of them appeared on Skype and we were talking for more than one hour. They sent me a payment order of 280euros (which I paid) via, which seems to provide services of this kind. In "terms and conditions" of this site it is stated that you can claim a refund within 2 days, (not after 3 months as the Indian guys said to me). I sent a mail claiming my refund immediately, but it was never delivered as both their e-mail addresses couldn't be found.
    When the Indian guys asked for more for adjusting my CV and making my webpage, I refused, and started to be suspicious.
    I am not sure about all this, because it is too soon to say anything, but reading your messages and this article I do believe that something is wrong.

Where does the information on telephone numbers come from?

tellows provides a platform where those who receive frequent spam and scam phonecalls can share their knowledge on a particular caller by commenting on the phone number's profile. Profiles are generated automatically if a number is being searched for the first time. We categorise calls by type (debt collection, sweepstakes, etc.) and give the number in question a tellows score, which indicates whether a number is trustworthy or suspicious, helping you to decide whether or not to take the call. This risk rating is generated by a complex algorithm that incorporates data such as user ratings and search statistics. Want to find out more about how the tellows score works?
The bulk of the information on the site comes from user reviews and our database is constantly expanding and becoming more detailed thanks to information from you, our online community. By providing information on a number, you can help innumerable other people to anticipate and avoid a malicious call.

  5. Lizi reported Remote Security with the number 01982551287 as Harassment calls

    Called my elderly grandad just now (isn’t the first time). He couldn’t understand him so passed the phone to me. An Indian man calling from “Remote Security” and enquiring about a “computer or laptop in your house” I told him we didn’t have either and he carried on trying to talk, so I repeated that we didn’t have either and to not call again and he hung up. Expecting a call again tomorrow as that’s what happened last time I told them not to call
