We use a product from Trans Union. It scores the the likelihood of the information the prospective customer listed as being accurate for one thing. If the address or phone number etc are out of area or if they can't match up the information we have with the database, they get a low score. If the score is too low, we don't open the account. This is supposed to help weed out fraudulent potential "customers" that are presenting ID or other information that don't add up.
