My memory is fuzzy, but I believe this depends on an issuers and acquirers. There are acquirers who do not check for anything but card number, expiration date and optionally CVC. And there are issuers who do not have AVS (address verification) support, which I think is almost all issuers outside the States. Most modern payment gateways will enforce CVC check, and require the name to be present, though.
