I've had a few issues with VISA/MC but not as much problem as with AmEx. However, all of my VISA/MC accounts are issued in the U.S., even those that I use my Danish address. Usually in the zip code field, they will use the code '00002' for foreign addresses, and as long as I enter that, it will go through. Sometimes I have trouble if the website only provides a dropdown menu for 'State' or has the state as a required field. I've never tried to use a VISA/MC that is issued outside of the U.S.
