Obviously for non-us customers whose bank does not support AVS you can't use it. Authorize.net lets you configure which AVS responses will result in a rejection and which will not (the actually give you a stupid amount of flexibility allowing you to reject AVS matches). So if you want to check AVS for US customers, but allow non-us customers to purchase without the check, simply configure Authorize.net to accept the G, U, and S responses. You can still reject US cards that don't meet your desired AVS level match.
