I am aware of that. It’s different in almost every country.
In Netherlands we have different postal codes for each side of the road, and long roads can have multiple codes for each side.
If I would address a package as NL2135ER44 then that fully identifies my former address (it’s even searchable in internet).
In USA you can’t address without mentioning the state because there are multiple cities of the same name across states.
IMHO Being only half aware of differences between countries would trigger at least some curiosity.
Now the real question is whether certain people are aware that a foreign country might be different from their own. I’d expect someone who lives 90 days in a new country to have some of that awareness.
But seeing the responses here it seems like I set the standards too high. For which I apologize.
