We don't have our National ID Numbers yet. We applied, of course, but they must be mailed. Snail mailed. And no, they cannot be mailed to one's work address. So how does one know where The National ID Number should be mailed... because remember, one doesn't have a permanent address yet or phone number, because... etc. I guess I should count myself lucky that they let me buy a bus pass without The National ID Number.
Certain Americans who think that the UN and social security numbers are a sign of the Apocalypse would not like this aspect of Swedish bureaucracy, I suspect.
