Hi Product Hunt 👋 If you've ever moved to Italy — for work, study, or residency — you've hit the codice fiscale wall. It's a 16-character code the Italian tax system derives from your name, sex, date of birth, and place of birth, and you need it for basically everything: a bank account, a phone contract, a rental lease, a job. The existing tools that calculate it are mostly ancient, ad-cluttered, and — the part that bothered me — they send your personal details to a server to do a calculation that's just a public algorithm. For a piece of data this personal, that felt wrong. So I built CodiceFiscaleRapido with three rules: 🔒 Everything runs in your browser. Your name and birth date never touch a server. It's a deterministic algorithm — there's no reason it should. 🎯 Accuracy over everything. The hard part isn't the algorithm, it's the data: every Italian comune and every foreign country has a cadastral (Belfiore) code, and most tools have stale or incomplete tables. I built the calculator on a complete, current dataset — including the foreign-country codes expats actually need. ↔️ It works both ways. Generate a code from your details, or paste a code to reverse it — extract the birth date, sex, and birthplace, and check whether it's valid. No signup, no ads shoved in your face, no data collection. Just the tool. It's genuinely useful if you're relocating to Italy, doing paperwork for someone, or just curious what your code encodes. Feedback very welcome — especially from anyone who's fought Italian bureaucracy and has ideas for what to build next.
