I would warrant a guess that they're doing a number of signalling queries against a number: checking for call-forwarding, asking what the location of that number is versus a proposed location from a customer and then based on a number of these factors, producing a score. How they recon they can profile a number without associated history of a number, I don't know. If you know SS7 signalling and MAP queries, you can probably guess how to do this.
