Sweden's personnummer system is much more elegant - your code is your date of birth followed by a 4-digit unique identifier.

Everybody knows their personnummer by heart, while in Italy most people carry their health card around with the 16-character codice fiscale.

Well in Croatia OIB is a random 11 digit number, but still most people I know managed to memorize theirs, especially if you're an entrepreneur running a business and have to fill it all the time.

Cannot say about Sweden, but most people I know in Italy also know by heart their Codice Fiscale (whether they carry with them nonetheless the card is another thing).

I know mine by heart and I still get mildly surprised reactions every now and then when I give it to an office worker.
