Would you like to know who called you?

This is how tellows works

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.

Check out our tellows blog for news on the latest scams, tellows products and updates in telecoms regulations that affect you in the UK or simply grab a copy of our free tellows magazine, which came together after our many years of experience on the subject of telephone terror and scams.

    A call from London, i did not respond because these are usually spam calls. The earlier comment from south african cindy indicates the same

    Website design from India. They use details from domain registrations (but these calls never identify where they got my mobile number).

    Silly thing is I manage hundreds of domains and do website design myself.

    I use a spare Android nobile with call blocking to dump any unknown numbers direct to voicemail so it costs them for every call, and guess what, they never leave a message!

    With 4 calls in 2 days it also seems like they will keep trying and not cut their costs.

    Pushy marketing caller with no leads. Obviously just read the company name on the attendee list of a recent trade fair, which was name-checked.

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.

    Called my mum on her mobile telling her that it was an emergency and she needed to leave work. Then called saying he was from a debt collector and tried saying that he was a private investigator. Each time we put the phone down he called back. He became very abusive blocked but no doubt he will try and call back
