Hi Silly
I had a chargeback recently on an order, it was low value and just a couple of soft toys. Went through protx as low risk, the guy was in the US, ip was in the US but wanted to ship to a friend in Thailand, i even emailed him
Don't ship to Thailand or anywhere else in Asia, Africa, Middle East, Eastern Europe, South America and only send orders to the States if the shipping and billing addresses are the same.
Sounds like you could be losing out on a whole lot of business but in reality the UK, mainland European and US markets are plenty big enough without risking high-risk zones.
For orders of high value phone the customer on the basis of a 'customer services' call to ask them to confirm their order and address at which their card is registered.
Insist on landline telephone numbers during checkout (or registration) rather than mobiles.
We've an article here on
fraud prevention that covers a few other techniques that should reduce your fraud by up to 95%.
Sadly the other 5% will be attempted by gangs with rented UK addresses, perhaps a perp on the inside of the Royal Mail (we've had direct experience of that more than once) and will require a sense born out of experience whether or not you think there might be a risk with this one.
And of course the banks stack chargebacks against distance sellers so when you do post high order values out, use a courier who provide full tracking of your parcel from collection to delivery. Oh, and avoid Paypal if you really want to avoid undefendable chargebacks.
