    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.

    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.
