Why Score?

Score analyses multiple data sources to form a consolidated view on any number in 60 countries and presents it as a credibility score. This allows users to make reliable and informed decisions about potential customers. Our platform handles billions of queries every month. We can draw on both live telco data and historical records over many years. No other provider in the market can provide such a scale of insight

Score uses a range of both deterministic and probabilistic data to evaluate the trustworthiness of a number. Both can be considered by the algorithm to build a nuanced picture of a number’s history and reliability in milliseconds


Score’s algorithm is constantly being refined: as we see more numbers, build more history and call out more suspicious behaviour, we learn and improve our detection capabilities still further


The data that is used within the Score algorithm includes many real-time indicators that show not only if a number is valid, but whether it is in long-term, regular and in constant use. This helps defeat attempts to use ‘disposable clean numbers’ to facilitate fraud

Score FAQ

Score is everything that we know about a phone number, distilled into a single actionable value. Score gives a credibility level that you can attach to a given number that ranges from 0 (least credible) to 100 (most credible).

You should think about Score as giving you some useful guidance in how to trust the number that a new or potential customer is giving to you. We would recommend that a score below 50 should be treated with extreme caution and perhaps that you should perform some additional checks before you take it at face value, whilst scores over 75 indicate that you can be reasonably confident that the number is genuine and has a tangible level of both history and activity associated with it.

Only the mobile telephone number is needed. We don’t require name, address or any other personal information (although we also offer services that can check these too!)

Depending upon the country, there are many different individual data points that are combined to give the Score. These include:

  • Recent and historical network (porting) movements
  • Frequency that a number appears in connection with sending calls and messages
  • Lists of numbers known to be associated with fraud
  • Real-time queries into the Global Mobile Signalling Network
  • Wide footprint on for example popular business and social media platforms (specific to the country)
