Latest from our blog



    We've all had to deal with the same thing. Your phone rings 24/7 and shows no sign of stopping, but if ever you should pick up, all you hear is the incessant yabbering of a telemarketer or nothing at all. You're infuriated by the anonymous calls jamming your phone line. Is there some way of finding out who is on the other end? Do you pick up or leave it ringing? Who is calling?
    Sound familiar? There are thousands of people asking the same question every day. In response to this universal problem, tellows functions as an online database of telephone numbers associated with spam and scam activity reported by you, our users. By sharing your experiences with unknown numbers, you'll be providing vital warning information to other users unsure about whether or not to trust a certain caller. The more information is shared, the bigger the database grows and thus the chance of finding out who's at the end of that anonymous call becomes higher and higher. Thanks to the tellows app you can identify unknown callers on your iPhone and Android! Whilst you are at it, take a look at our various other useful tools in our tellows shop today.
    Here at tellows.com, 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.
    Used by over 200,000 people daily, tellows provides its services to people in over 47 countries, but tellows.com is geared specifically towards those residing in North America. Want to hear more?

      Calls once a week about a property I am supposedly selling. Never mentions the name of the company he works for, but asks to call back at their "office number" 2676338386. I have the caller's number blocked but I still get messages constantly.

    Where does the information on telephone numbers come from?

    Huge amounts of data are entered into tellows sites worldwide each day - further comments on existing numbers as well as entirely new number profiles from first-time searches - all thanks to our users. User contributions are key to tellows' central function: the tellows score. Each time information on a number is given, the information is put through a complex algorithm to generate a trustworthiness rating, on a scale of 1-9. The respective score is clearly displayed at the top of the profile page for each number, making identifying an unknown caller possible in a matter of seconds and saving you not only time, but the frustration of dealing with annoying sales calls.

      2/13/25, 4:17 PM

      We are a dental office. They did the exact same thing to us. Yelled, screamed and told us someone was on the way to shut off our power for not paying the bills. Our power bills are on autopay. Called the # just to see and it sounded real at first but then we told them we knew this was a scam, they screamed and yelled again to scare us and then hung up. We double checked our bills and it was fake. Please be aware-this is a complete scam.

    4. Nope reported Elisa Summers with the number ‎6106723588 as Telemarketer

      2/6/25, 7:33 AM

      Very perky woman's voice -- "Elisa Summers" -- calling about an "unclaimed reimbursement credit" to my "electricity supply account ending in [some numbers]...." Funny how they don't actually say what company they're calling from. Also funny how I don't even have a separate account with my "electricity supplier" -- my supplier and distributor are the same (PPL Electric). But sure, I'll definitely call you back about that money that I didn't "claim"... [rolls eyes]
