Codice Fiscale Calculator
Calculate an Italian codice fiscale from name, date and place of birth, or check a code and read back what it says.
What it does
Codice Fiscale Calculator shows the whole calculation, not just the answer: every intermediate figure is on screen, so you can check it against your own numbers instead of trusting a single output box.
When you need it
Quoting, invoicing, or checking someone else's arithmetic — the moments where being roughly right costs money, and where the formula is easy to get subtly backwards.
Limits and caveats
Figures are unrounded until the final display, so results will not always match a calculation that rounded at each step. This is a working tool, not tax or financial advice, and local rules may differ. Everything happens in your browser, so the file never leaves your device.
How to codice fiscale calculator
- Type the surname, name, sex and date of birth.
- Start typing the comune — or the country, if born abroad — and pick it from the list.
- Copy the code. Or switch to Check and paste one to see what it encodes.
Frequently asked questions
- Is the result my official codice fiscale?
- It is the code the rules produce, which is the official one for almost everybody. The Agenzia delle Entrate assigns the real code, and when two people would get the same one it changes some digits into letters — omocodia. Your tessera sanitaria shows the official code.
- My comune no longer exists. Can I still calculate it?
- Yes. The list includes the comuni that were merged or renamed, because someone born there keeps the old code for life. They are marked as former comuni.
- What does the check tell me?
- Whether the code is well formed and its last character matches the other fifteen, plus the sex, date and place it encodes. It cannot tell whether the code belongs to a real person — only the Agenzia knows that.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
