That isn't too different from America, where you have a social security number, driver's license number, passport number (possibly two if you also have a passport card), and any other random identification the government demands.
In the us several of those are administered by different governments (state v federal) and at least one is literally forbidden from being used as an id number because the numbers are reused (but everyone does anyway).
Most people in the US only have the first two only ~46-51% of people in the US have passports and way fewer actually have a passport card on top of that. That's the majority of ID numbers most people have to keep track of.
