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.

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. Boo reported unknown with the number 08443373963 as Harassment calls

    I made the mistake of answering the phone to this number in early June. A recording claimed I had won an i pad and to phone a PREMIUM rate number to claim it. Obviously a SCAM. I barred the number but every week I get a voice mail from this number saying something about pressing 9 to cancel. DON'T press 9. It's will call a PREMIUM RATE number. There is no way to stop these people. All you can do is bar them and check who called before checking your voice mail. These CRIMINALS are really irritating me and I'd like to see them in prison soon.

  2. David Schofield reported Energy audit with the number 08443373970 as Telemarketer

    I have been called 12 times since June 9, 2016. They first say The national date base shows you have not had an energy assessment. I HAVE had a recent energy assessment. I do not like these calls and I think they are connected to my phone hacking problems. I get at least two marketing calls a day not all from this number and I think they are linked to a local call center that may be hacking my line. The call center is on the Isle of Bute in Scotland. If anyone knows anything about this please post your experience. Thank you.

  3. N/A reported Microsoft Campus with the number 02081507542 as Cost trap

    Said he was from the Microsoft Campus and my computer was being used by hackers. When I asked him how he knew my computer was being used by hackers he told me that they had my laptop ID number, when I asked him to read the number back to me, he told me it would be easier for me to read it to him and then he could confirm. I pressed him, as I've never registered my landline with Microsoft, and then he said that I was supporting the hackers and he would be forwarding on my information to the police.

    Aggressive, and obviously trying to acquire personal information over the phone.
