Unfortunately, we had to block non-US merchants due to heavy fraud concerns. As it turns out, the majority of transactions placed with non-US merchants using Masked Cards have been initiated by fraudulent users. Although certain non-US countries are not of particular concern, we're only able to separate merchants by US and non-US, and are not able to allow specific "safe" countries at this time.

The plan is to allow non-US merchants again within the near future, but we will not be able to do so until we're confident we won't see the same negative consequences we were seeing previously.
