The stuff I sell isn't much of a target for fraud so I don't have much experience weeding out fraudulent orders, but I just received an order that seems fishy.
The billing and shipping addresses match but AVS says there is only a zip code match to the billing address. They entered their email address but not their phone number. Should I call my payment processor to find out the issuing bank and call the issuing bank to get the customer's phone number to verify the transaction? Is there a specific term I should use when asking the bank for the customer's phone number?
