I believe Germany might be a decent example to look at too, with their
rather recent history and reasonably large population. Apparently,
even the German tax agency will issue _multiple distinct_
identification numbers to be used by _the same individual_ but for
different purposes.

When you're designing systems pretty much from the ground up and _on
purpose_ to make it difficult to correlate and aggregate data between
different systems and databases, that leads to some interesting design
choices being made.

Legal requirements being one aspect of those.
