Partita IVA Checker
Check an Italian partita IVA's check digit on your device, with links to confirm it is in use with the Agenzia delle Entrate or VIES.
What it does
Partita IVA Checker 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.

Frequently asked questions
- Does it tell me whether the business is active?
- No, and nothing that runs on your device can. The check digit shows whether the number was typed correctly. Whether it is in use is in the Agenzia delle Entrate's register and, for EU trade, in VIES — both are linked from the result.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
