Been doing that for years, some of them just don't listen. One thing to be careful about, in my experience, is if you have a joint credit card with your spouse that has the same number on both cards. If I was trying to use my card overseas while my wife was using it in the US they would often block purchases. Interestingly the purchase they would block would often be my wife's purchase back in the US, while my multi-thousand purchase in Asia would sail right through.

There is no rhyme or reason to how those algorithms work.
