In addition they also encode (binary) gender which means they’re terrible for trans people (not to mention nonbinary people more generally) because it means anyone can search databases for trans peope. Just find everyone whose number encodes a gender that does not overlap with their name’s.

You can get it changed, but only after getting a dysphoria diagnosis and a recommendation letter from a doctor and then applying to a specific committee, a process that currently takes more than five years (I don’t know how much more because I’m still waiting).

And then of course it’s an administrative nightmare to get in touch with everyone and tell them you’ve done something that usually is seen as impossible since personnummer are meant to be primary keys in society’s database.

Wow, that's a huge design flaw. Such a number should be opaque (the Dutch BSN is), but Sweden's number just puts the date of birth and gender in the number there for all to see.
