How do you perform a manual AVS and CC's phone number check?
The only information I have is what is provided by the customer on my website; so I have no other information to check against what they provided is accurate.
You are right, I should switch this back to allow for a different shipping/billing address. I will give this a try to see if this works and hopefully it doesn't cause an increase in fraudulent orders.
However, one thing that I have noticed by keeping the shipping/billing address the same. Anytime a customer needs to ship to a different address I usually receive an email from them asking me. I then allow them to ship to the new address and I make the change on my website.
I think it seems to weed out any fraudulent orders if they see that the shipping/billing address must match.
I actually do record all IPs and ISPs of orders submitted through my site, but never really used this as a fraud check.
To do this I would just check the IP location and see if it matches the address location of the order?
