Ah yes personal identification numbers (BSN in Holland) don't 'spark joy' either. In Holland every resident gets a unique BSN. So you can use it to uniquely identify a person. Except if you also have to deal with asylum seekers, because they get a slightly different kind of number which will be reused after the asylum seeker is granted/denied residency.
