Cycling through all six. Tap any point to stop.

Measured on six things

Strumento gratuito per calcolare, decodificare e verificare il codice fiscale. Strumento indipendente, non ufficiale: il codice ufficiale viene rilasciato solo dall'Agenzia delle Entrate.

Security

HTTPS enforced with CSP, SPF and DMARC, and the client-side-only architecture is a real privacy strength. But HSTS, frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy are all missing (6/12 headers).

About this app

CalcolaFiscale.it is a lean, privacy-first web app that handles the three things most people need from an Italian codice fiscale: calculating one, decoding one, and checking whether a code is formally valid. Everything runs client-side in your browser — no data is sent, stored, or shared, and no account is required. The calculator composes the 16-character code in real time as you type surname, name, birth date, sex, and birthplace, with a per-character explanation, copy button, QR generation, and printable output. The decoder pulls out birth date, sex, and birthplace while being refreshingly honest about what the algorithm can't recover (full names). The validator checks structure, date plausibility, and the control character, pinpointing the exact character that's wrong. What makes it stand out is the coverage for people born abroad — 120 foreign states with dedicated codes and country-by-country guides (Albania, Romania, Ukraine, China, Morocco, Philippines and more), a scenario...

Scout Review

Written by AI from measured evidence, scored out of 100.

CalcolaFiscale is a lean, well-built Italian codice fiscale tool that does three things — calculate, decode, verify — and does them fast and privately. The editorial design is a cut above the category, the client-side architecture is genuinely snappy (97 mobile / 100 desktop), and the foreign-birthplace coverage is a real differentiator. The gaps are unglamorous but real: missing security headers undercut the privacy pitch, contrast and ARIA issues undercut the accessibility, and the page buries a simple tool under a long marketing scroll. None of it is hard to fix.

Measure by measure

Usability

Clear tab→form→calculate path with helpful date format hints and privacy badges at entry. The result panel is an empty placeholder and the page turns into a long marketing scroll after the form, slowing the simple lookup.

Design

Editorial serif/sans pairing with a disciplined burnt-orange-on-near-black palette and a working calculator above the fold. Held back by weak helper-text contrast, repeated 'non ufficiale' disclaimers, and an unclear catastal-code field.

Speed

Lighthouse 97/100 mobile (LCP 1.0s, CLS 0, TBT 71ms) and 100/100 desktop. Client-side computation means no server round-trip for the core calculation — genuinely snappy.

Security

Accessibility

Lighthouse 93/100 with a responsive, keyboard-navigable layout. Failing audits on prohibited ARIA attributes, insufficient contrast, and label/accessible-name mismatches; Italian-only with no published a11y statement.

Growth

Real recurring need with a genuine wedge: 120 foreign states and omocodia handling that generic calculators fumble. But the free official Agenzia tool caps the ceiling — this is a convenience layer, not a moat.

Improvement areas

Missing security headers (HSTS, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy).
Accessibility failures: contrast on helper text, prohibited ARIA attributes, label/accessible-name mismatches.
Repeated 'non ufficiale' disclaimers and an unclear catastal-code field hurt trust and clarity.
Result panel is an empty placeholder with no preview; long marketing scroll after the form.

Design & Usability

The design punches above the utility-tool category: an editorial serif display over sans body, a single burnt-orange accent held consistently across tabs, buttons and stats, and the working calculator sitting above the fold so the tool is usable before any marketing copy. Usability follows the same discipline — a clear Calcola/Decodifica/Verifica tab, format hints in the date fields, and privacy badges at the point of entry. Two things drag it down: helper text is small grey on near-black and fails contrast, and the 'non ufficiale' disclaimer repeats so often it becomes noise rather than trust. After the form the page turns into a long marketing scroll, which is a lot of real estate for a one-minute lookup.

Speed & Security

Speed is the standout: Lighthouse 97/100 on mobile (LCP 1.0s, CLS 0, TBT 71ms) and a clean 100/100 on desktop, and because the calculation runs client-side there's no server round-trip to wait on. Security is more mixed. The privacy-first architecture is a genuine strength — no account, no data sent or stored — and HTTPS, CSP, SPF and DMARC are all in place. But the header probe found HSTS, frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy all missing (6/12). For a product whose entire pitch is 'your data never leaves the browser,' the missing hardening headers are an easy, cheap fix worth making.

Accessibility & Growth

Accessibility scores 93/100 on the automated audit with a responsive, keyboard-navigable layout, but the failing checks are telling: prohibited ARIA attributes, insufficient contrast, and visible labels that don't match their accessible names. The contrast failure hits the helper text that explains how to fill the form — the worst place to lose it. There's no a11y statement and the site is Italian-only. On growth, the idea is sound: codice fiscale calculation is a real recurring need, and the 120-country foreign-birthplace support plus omocodia handling is a concrete wedge that generic calculators fumble. The honest limit is that the free official Agenzia delle Entrate tool is the authoritative source, so this is a convenience-and-privacy layer — valuable, but not a moat.

Conclusion

For anyone who needs a codice fiscale in a hurry and doesn't want to hand their data to an ad-farm calculator, this is a solid, honest choice — and the foreign-born support is the reason to pick it over the generic options. Fix the headers, fix the contrast, trim the disclaimer repetition, and this moves from 'good utility' to 'genuinely excellent.' The bones are already there.

Suggestions for improvement

Add HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy and Permissions-Policy — the privacy pitch deserves the full header set.
Fix the contrast on helper text and the ARIA/label-name mismatches flagged by Lighthouse; add an accessibility statement.
Consolidate the 'non ufficiale' disclaimer to one clear placement instead of six repetitions.
Give the result panel a preview state or example output so users know what to expect before calculating.

Agenzia delle Entrate — Verifica Codice Fiscale

The official Italian Revenue Agency service for verifying a codice fiscale. Authoritative, but limited to verification rather than calculation or decoding.

CodiceFiscale.io / generic online CF calculators

Various third-party Italian codice fiscale calculators and decoders. Many rely on server-side processing or ad-heavy interfaces and often lack robust foreign-birthplace support.

INPS / government portal utilities

Public administration portals sometimes offer codice fiscale lookups, but typically require SPID/CIE authentication and aren't designed as quick standalone tools.
