I have three official first names but the second is the spoken first name — a practice not uncommon in Sweden. I use only the spoken first name for most things, but all three are present in e.g. healthcare and social security databases: where the spoken name is supposed to be underlined. But the underlining often gets lost when transferred between systems, and some systems even strips away all but the first. My last name is spelled with a double-s by one side of the family, but with a single s by the other. I've been refused to pick up packages at the mail-parcel centre only because the spelling on the parcel did not match my ID card, despite having a notice slip with delivery number that had been delivered correctly to my physical mail address.
