Latest from our blog



    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.

    1. Fran Donne reported Estate planning spam with the number ‎02922722140 as Harassment calls

      5/8/24, 7:50 AM via iPhone App

      Sam from the Estate Planning Helpline was there. asked how I was feeling today. Even though we're TPS, he still called. When challenged further, he responded "not to worry" and hung up. When queried for his business address, he said, "based in south west London." They seem to be a reputable company, however they don't seem to have a website.

    5. Perry Wolice reported Medical scam with the number ‎03308087775 as Harassment calls

      5/8/24, 7:43 AM via Android App

      They took a lengthy time to reply, implying that the caller is not genuinely from the UK as it appears. For the first ten seconds, I was silent, as if shocked that I could hear. The woman said she was calling from the "UK Health Association" and gave her entire name.

    Where does the information on telephone numbers come from?

    tellows provides a platform where those who receive frequent spam and scam phone calls 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. PSF reported unknown with the number ‎+441243212675 as Telemarketer

      4/30/24, 11:24 AM

      Sounded very fishy, they called my work landline number asking for details about me (managing director) said it was about the phone lines, I told them we don't have any at all and work off mobiles so it's not relevant, but they continued to push for information:
      Gave me slightly wrong address wanting me to correct it, asked me to confirm MDs name but gave slightly wrong name and wanted me to correct it, asked when the MD is in the office, which days of the week.

      be very careful, they're positioning questions so that they can record your voice giving your name and address
