Calcolo OK

CalcoloOK is a bilingual (Italian and English) browser-based calculator for estimating the Italian codice fiscale (tax code). It performs the calculation locally in your browser, so the data you enter is not sent to a server, and no account is required.

Features:
- Client-side generation of an unofficial codice fiscale estimate from name, date of birth, gender, and birthplace
- Automatic cadastral/Belfiore code lookup for Italian municipalities and foreign countries
- Educational format checking with clear disclaimers that results are not official
- Bilingual interface (Italian and English) with localized content
- Structured data markup (JSON-LD) for WebApplication and FAQ pages

Typical uses:
- Preliminary personal data verification before submitting forms
- Checking consistency of received client fiscal codes in small offices
- Understanding how name, date, gender, and birthplace contribute to the code structure

CalcoloOK is not an official Agenzia delle Entrate service and does not provide legally binding tax code assignment. Results are offered as an educational estimate and should be confirmed through official Agenzia delle Entrate channels before use on official documents.
