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.

  1. Fen reported unknown with the number 01327596878 as Telemarketer

    Missed call from local number. When I called back, answered immediately and knew my name, so clearly some form of caller ID linked to local names.

    Asked if I had had sofits and gutters replaced. Told them I was TPS and never to contact me again.

  3. Grumpy reported unknown with the number 0141537400 as Unknown

    This number called on my mobile telephone while I was driving. By the time I stopped it had stopped ringing. Later I found the number had called me at home. I always check numbers before I ring back. Comments made on other sites are unfavourable, putting it mildly, so I am taking them as a warning and will not be calling back.

    This is a scam call. Automated voice saying they are from the IRS and that they are filing lawsuits for collections. Report to local authorities if you receive this call immediately!

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.
