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.

  2. Grumpy reported Talk Talk fake with the number 01782746924 as Harassment calls

    Thr crooks used this false number to call me and say by means of a recorded woman's foreign-sounding voice that my internet line would be disconnected today. I did not wait for any more before hanging up. I have been getting similar calls two or three times a week, and many more from similar people using their trickery to try to persuade me to give them access to my computer - all because of the leak of personal information by Talk Talk.

  3. Tasker reported ? with the number 01612497204 as Unknown

    Rings me several times most days. It either rings off before I get the chance to answer, or hangs up when I do answer. Very annoying. I have the phone allocated for these types of call so it is not my main.

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.

    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.
