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.

    Where does the information on telephone numbers come from?

    tellows provides a platform where those who receive frequent spam and scam phone calls 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. M york reported Housing Association spam with the number ‎02081490744 as Aggressive advertising

      7/23/24, 2:46 PM

      Welsh accent, wrong personal details, persistent calling, six times in three hours, calling about ‘mould in my property’ (I own my property outright it has never been housing association). Avoid, block. Though they call back from new numbers.

    2. Steven Williams reported Energy saving scam with the number ‎01792722610 as Harassment calls

      7/19/24, 9:34 AM

      Guy just called me offering 30k grant for energy upgrades. Said he's spoken with my father. He'd passed 30 years ago. Then said he's spoken to my brother about it. Absolute garbage. Promised 25-30 degrees from an ASHP. I'm in renewables so quizzed about my mothers DHW and Space heating demand, COP etc. Clueless. What a joke.
