The non US companies I have tried this with in the past also had a US number, but their receiving account was non-US and I am fairly certain that is what they trigger off of. The protection in place is intentional and if anything I have asked the bank for even tighter controls. I want something closer to the 3rd parties that allow making specific rules, unique card numbers for specific vendors but getting a bank to do that is difficult. My card does not have strict foreign alerting, it has explicit blocks of non US that I put in place. If someone outside of the US tries to use the card, it completely disables the card until I walk into the bank which is not a problem as they are just down the road and they all know me. The only option with Fastmail is to disable my protections for a day. I don't mind that as they have earned some limited trust from me and they are inexpensive. VPS and server providers can get more expensive really fast so I am less inclined to do that unless they show up as a US entity as far as the bank can see. That's why I was asking if others here also had to disable their protection or if they know for certain they show up as a US entity.
