A codice fiscale is just a way to determine some pieces of information about a person. It's composed by:
- 3 consonants from the surname
- 3 consonants from the first name
- the last two digits of the birth year
- a letter for the month (every month has its own)
- the two digits of the day of birth (+40 for women, to recognise the gender)
- a code made by a letter and three numbers, depending on the Comune of birth, every Comune has its own)
- a letter, not determined by something, but different, in order to recognise people with same name, and born in the same day and in the same Comune.
So, everyone could have one.
