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, 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.

  1. Kymnarkmar reported Microsoft with the number 01614081867 as Cost trap

    They rang me twice this afternoon so say my computer has sent them an error. I asked them to remove me from their call list and they told me it would cost £59 to do so.
    I told them to f**k off and hung up.

    My wife and I both recently made a charity donation. Had to give our mobile numbers to complete. Now we both get at least 1 call per day from this number. Sad. Brings the whole of the charity business into disrepute.

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.

  5. Snailalot reported Unknown with the number 01604761440 as Telemarketer

    Regularly get 4/5 calls a day from this lot. Never been in when it happens but tried ringing the number back and get "Number you have dialled has not been recognised."
    Registered complaint at Ofcom (no reply yet), tried blocking it but that doesn't work as it's not recognised. Even complained to my phone provider. They said these calls are coming in via the web and basically "hacking the system". Nowt they can do 'cos they are untraceable. Was advised to report it to the police, get an incident number then ring them back and they'll change my number. It seems the powers-that-be are actually powerless to do anything about it.
