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 overenthused telemarketers or, perhaps even more annoying, a swift click and the dialling-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 phonelines, 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 kind 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.
Would you like to hear more about the latest scams, tellows news and updates in telecoms regulations that affect you? Take a look at our tellows blog.
Check out our stats page for a heatmap displaying regional nuisance-call trends and numbers currently displaying high levels of activity.
We also automatically pinpoint the location in which your call originated and and display it on a map, using the dialling code. Learn more about international dialling codes.
tellows is an international community operating in 47 countries with more than 200,000 users on a daily basis. tellows.co.uk is tailored specifically to suit the needs of people living in the UK.

  1. 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.

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. Arty reported "Windows" with the number 02031291358 as Harassment calls

    Just had one of those calls that pretends to come from Windows, but is really a load of bollocks. Well I decided to play him along, pretended to press the buttons he was telling me to and told him what he said to do had brought up a firewall block (I pressed nothing and didn't type what he told me). Then i pretended i couldn't hear him well because the line was bad and he gets a little bit aggressive and tells me "I am going to come along and f*ck you tonight, yes I am going to f*ck you very hard". Well I just p*ssed myself laughing and eventually so did he. I then said I think it's about time we end this conversation don't you and he asks me how old I am and I say 54 and he says "well I bet you're still horny, I'm still going to come and f*ck you tonight"
