Fraudulent orders

Most payment processing companies wil automatically check orders for obvious signs of fraud and / or allow you to set the conditions yourself through their admin area. Checks are often made on AVS, CVV but may include transaction amount, known bad IP addresses or ranges as well as rapid multiple orders amongst others.

The important consideration is not to rely 100% on your payment proceesor to pick up on fraudulent orders and that is why we recommend manually reviewing each and every order. The steps below are a guide to checking for fraudulent orders.

  • Closely check all orders and double check totals in your payment provider control panel.
  • Check the IP address of the order. Use a site such as Hexillion to match the IP address of the computer with the address of the customer.
  • Check the address and telephone number of the customer. Use a service such as White Pages or Infobel, you can also often search on a person's name on Google to find out details about the buyer.
  • Always double check orders where the customer uses a free email account such as Hotmail, Yahoo, gmail etc.
  • Always double check orders where the shipping address is a PO Box.
  • Always triple check orders where the shipping address is different to the billing address.
  • If in doubt telephone / email the buyer to check their credentials.
  • If you are still in doubt, cancel the order and don't ship. Chargebacks will cost you more and may compromise your merchant account.
  • Avoid accepting personal checks - they can easily be stopped.
