How is your Swedish ID created?

Do you want to understand how your Swedish identity number is created… or maybe not, it is explained here. If you know how it is calculated after the first 6 digits which is your date of birth, then it must be pretty easy for others to work this out?

Although I did get from a source that one can just ring up the Swedish Tax Agency and ask for any Swedish residents personal ID. I haven’t tested this yet.. but I am sorely tempted to try 😉
