We categorise calls by type (debt collection, serious number, 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.

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. 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 tellows.co.uk, 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.

      phoned my partners phone so I took the call as she's disabled. Persistently tried to sell me the iphone for like £35 a month. Claimed to be from EE, later claimed to be a Partner company of o2 and Vodaphone and Three. told me I was a good customer so I said I'd only had the phone a month, Actually had it 2 years. told the foreign caller She's breached PECR as they shouldnt be calling and could be fined up to 20milliion Euros or 4% of their turnover, didnt phase her at all so I continued to repeat the law to her. Said if they were a partner of EE they would have checked the TPS register so they'll be fined.

    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.

      Lady calling herself Janet Wilson requested access to my laptop in order to fix an issue with our broadband router. Very difficult to understand her due to a very thick foreign access. When I started to ask questions about Virgin and the specification of the new router she said she would be sending she hung up.
