    Where does the information on telephone numbers come from?

    The main indicator of a number's trustworthiness, the tellows-score, is the result of a complex algorithm that is fed by your comments and ratings on numbers. Your participation is the key to successfully counteract future spam and scam attempts, since the caller knows who he or she is dealing with prior to answering the phone. Share your knowledge on the trickery of dubious entrepreneurs and help to deny them their unlawful treasure on to protect fellow Australians from unwanted calls.

    With your spam reports, other people can easily distinguish spam from a genuine number and can pick up the phone without fear. It is never too late to help someone else before they fall for a new fraud. Scammers become more and more tricky and creative. In your comment, you can describe the fraud in details, so everyone knows where the thread is. Additionally, we recommend reporting scams to Scamwatch, the Australian authority for communications and media that can take further action and provides an overview and statistics about reported scams over the years.
