Latest from our blog

    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.

    2. xubbi reported Digital solutions with the number 02081610640 as Telemarketer

      Called to offer me a better third party insurance for my pipes and drains. When I explained the it’s all covered on my comprehensive buildings and contents policy she just hung up. So unprofessional....
      I rang the number back and got the company name and was also given the choice to opt out of “calls like this in the future” which I did. It’s an automated system so fingers crossed it will work.

    3. iPhone reported unknown with the number 02081610640 as Telemarketer

      Digital Solutions Market Research. This particular call was about replacing my ‘third party cover’ for my pipes and drains, which I don’t have third party cover and everything is covered on my comprehensive buildings and contents. The caller just hung up when I explained... I rang the number back where I got the company name from and I was offered an opt-out, which of course I did...

    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.
