[thelist] Authorize.net and AVS

[Hershel Robinson]

Our estore goes live tomorrow morning (including a major advertising 
campaign in print hitting the newsstands tomorrow). The xcart install 
using authorize.net for a gateway works with US credit cards. We tried a 
Canadian one and it failed. authorize.net had this to say:

=====
Most international orders will receive response codes of "G", "U" and 
"S". Most international orders will not receive one of the No 
Match/Match AVS responses as the majority of foreign banks do not 
support the AVS system. Authorize.net recommends that you employ your 
default settings, however it does not work for all business models. 
Please be aware that if you change these settings address verification 
will not be done on these transactions. you can take these settings off 
and see if that influence your shopping cart.
=====

We do indeed expect non-US customers. I am uncertain as to what 
percentage, but we without question expect them and of course want their 
business.

Are we thus left with no choice but to disable AVS security? In reality, 
I think many sites with which I am familiar do not confirm my billing 
address that it matches that which is on record with my credit card company.

Any thoughts on this?

Thanks,
Hershel
