Codice Fiscale Calcola FAQ
How does the calculator generate a codice fiscale?+
It combines surname, name, birth year, month (letter), day (plus 40 for females), and the Belfiore or Z code of the birthplace according to public rules.
What data is required to calculate the code?+
Name, surname, date of birth, gender, and either an Italian municipality or a foreign state's Belfiore code.
Is the generated code official?+
No, the tool produces a theoretical code; only the Agenzia delle Entrate can assign and officially verify a codice fiscale.
What is the difference between formal check and official verification?+
A formal check only validates structure and control character, while official verification confirms the code’s legal attribution via the tax agency.
Can I calculate a code if I was born abroad?+
Yes, by selecting the appropriate Belfiore code for the foreign state in the calculator.
Why might my calculated code differ from the official one?+
The Agenzia may apply omocodia, substituting letters for digits to differentiate people with identical data.
