It's very interesting to know that postal code verification isn't the global M.O... I've been curious about this for a while and you've provided some valuable context.

FWIW: the pump was asking for the ZIP code of the billing address you have on file with your bank. If I typed in a random ZIP code, my card would get declined. I'm pleasantly surprised someone actually thought to handle the "foreign address" case, even if it's silly that the machine forced you to provide a ZIP code in the first place. That's how low my bar is for payment processing networks, I guess.
