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.

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.

  2. eternal flame reported +2036300271 with the number +2036300271 as Unknown

    Numerous calls during July from this number, missed most as working. Tried to call back to find number didn't exist! followed by non-European message. Calls continued mainly around lunchtimes, 3 or 4 a day. My phone provider suggested I answer as unable to block on my contract. Finally answered a call. A woman speaking barely discernible English knew my name, and asked me to confirm. She said not to worry, she wasnt selling anything, but ringing from the British Security Service!! I told her I was extremely suspicious and asked her NOT to call anymore. I had one more call later that day. I have emailed the British Security service to advise them of this rogue caller.

  3. Annoyed reported Industrial Workers Union with the number 01325776588 as Harassment calls

    I've missed a number of these calls to my mobile. They have my full name and address, which is a little worrying. Said that I may have a claim for working in a noisy environment. I've been an office worker all my life. I asked if there was noise protection for phone calls from people like him. He started to get rude.

    When I mentioned that my number is registered with the TPS and he was now breaking the law, he said he didn't care as he knocked off in 20 minutes and it didn't apply to him and hung up.
