    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.

      First he asked for person on board of directors. Then the owner - neither of whom come into the office. He was ready for this- said he had sent a letter from his Director Simon Daniels to the owner. Wanted to leave a tel message - very pushy. Obvious sales call.

    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.
