@FuchsiaShock German drivers licenses and passports ("Personalausweis") have no gender marker. Never did (since 1945). And if even german bureaucrats don't need it, nobody does :)
these are the rules apparently
"month of birth (+5 for the first character if female)"
it looks as if the only reason it's in there was an assumption they could use birth sex as a simple way to separate all applicants into two numerical groups to try to uncluster otherwise not-evenly-distributed birth months
which really doesn't make a lot of sense when there are already random digits at the end.
A silly instance of Mastodon for queer folk and non-queer folk alike. Let's be friends!
