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.

  5. Grumpy reported Talk Talk fake with the number 02476685362 as Harassment calls

    This was one of the stranger calls I got. I put it under the heading Talk Talk Fake because the man knew my name, which was leaked to criminals, together with other personal information, by Talk Talk a few years ago, and I have been pestered ever since. The man said it was about my telephone bill and went on to suggest he knew how much I was being charged. I told him I was not following him very well - "but carry on!" At this point he rang off. It was an appalling line and I had asked him to speak more clearly. Afterwards I looked the number up and found, on other sites, that others had been pestered by people calling from it. These people are not to be trusted.

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.

  1. Jasmin456 reported BFI with the number 02088580126 as Telemarketer

    Female voice with Asian accent called my mobile and said they are offering financial advice. She did say thank you and bye before hanging up but not nice to receive a cold call on mobile number anyway.

  3. Paul reported unknown with the number 01454667540 as Unknown

    An absolute scam, they tried my parents who luckily got suspicious and cut them off. They have tried a few times since.

    Reported to BT and they confirmed it’s a scam.

    What a nasty group of people targeting the elderly. Karma will bite them in the arse eventually.
