> a national ID number isnt usually publicly available info
A couple of counterexamples:
Italy's "fiscal code" is generated with a simple algorithm which can be executed manually:

Sweden's "personal identity number" is public information and can be looked up by anyone:

Belgian National Number is your birth date, then an increment from 1 to 999 for every baby born that day, then a base-97 checksum.
Not sure if still the case: odd numbers for males and even numbers for females.
This also means a person’s Belgian RRN can change.
Yep, but they do not change on sex change, IIRC.
