    We've all had to deal with the same thing. Your phone is ringing and the display shows an unknown number you haven't seen before. So you're asking yourself whether to answer it or not!? Who is calling? You are certainly not the first one to ask these questions. For this reason, tellows developed a database which will help you with your decision about answering or ignoring the phone call. This will definitely save you time and energy. Yet, there is more to it. In addition to a risk rating, tellows provides an approximate location of the number calling. This helps you to find out the origin of the phone call.

      I got a call from an English speaking lady, telling me she is working for a trading company that is involved in crypto currency’s. She told me she would transfer me bitcoins on a special bank account. I had to online. When I asked her why I should trust her she hung up. I definitely think this is scamming. Last year I had the same experience and that cost me €200.

    The tellows community allows you to comment any telephone number. We analyze and classify the calls according to the type of call. The core of tellows is the so-called tellows score. A thought-out algorithm that classifies any number in relation to its risk level. This in turn makes it easier for you to decide whether it is safe to answer the call or not. In order to gather as much information as possible about all the numbers in question, we need your help! With the help of your comments about the numbers and your risk rating you certainly help us to enrich our phone number database.

      This is a scam # calling US residents, especially the elderly, telling them that the call is coming from the US Treasury telling the people that there is a grant in their name, for being a citizen with no criminal records and for paying their bills on time. They spoof the call so it comes through the caller ID as a A call from the US usually from Boston and Seattle. When I told him I knew his scam, he started to laugh and I asked what area code he was calling from, he couldn't give me the area code, and I then asked for the area code to Washington DC and he gave me the wrong ones, and then the call broke up as he was talking and the phone # was lost and disconnected. Within 10 seconds, he called me from this # and asked why I hung up. I told him he hung up, by the way, this man had a heavy middle eastern accent. When I told him I was recording him, he laughed again and told me I was being recorded. I laughed at him and he told me that I was being a dick and then told me I couldn't find him in 1000 years and then he asked if I was a Christian. I said I wasn't and he was laughing and whispering to someone else in another language which I couldn't understand but I heard the word "pussy", and when I asked what religion he was, he said Christian so I asked him to name the apostles which he couldn't and he then told me I was stupid and asked if I had children lol! I asked him to keep talking because the longer he talks the trace would find out his number and then his location down to the exact building he was calling from and he kept laughing until I said, "wow, that was quick!, Denmark is such a beautiful country, I can't believe they let you in!" He immediately hung up. If anyone in Denmark can trace the number 566897221, and find the location and alert the authorities, please do so immediately, thank you so much!
