Tutto quello che devi sapere sulla validazione P.IVA
Come funziona la validazione della Partita IVA?
La Partita IVA italiana è composta da 11 cifre e viene validata tramite un algoritmo di controllo simile al Luhn. Le cifre in posizione dispari vengono sommate direttamente, quelle in posizione pari vengono moltiplicate per 2 (sottraendo 9 se il risultato supera 9). La somma totale deve essere divisibile per 10.
Cosa significano le cifre della Partita IVA?
Le prime 7 cifre identificano il contribuente (numero progressivo), le cifre 8-10 identificano il codice dell'ufficio provinciale dell'Agenzia delle Entrate che ha rilasciato la P.IVA, e l'ultima cifra è il carattere di controllo.
Questo strumento verifica se la P.IVA è attiva?
No, questo strumento verifica solo la correttezza formale del numero tramite l'algoritmo di validazione. Per verificare se una P.IVA è effettivamente attiva e a chi è intestata, è necessario consultare il servizio VIES dell'Agenzia delle Entrate o il sistema europeo VIES.
Lo strumento funziona anche per P.IVA estere?
No, questo strumento è specifico per le Partite IVA italiane (11 cifre). Per la validazione di P.IVA di altri Paesi europei si consiglia il sistema VIES della Commissione Europea.
How does Italian VAT number validation work?
The Italian VAT number consists of 11 digits and is validated using a check algorithm similar to Luhn. Digits in odd positions are added directly, those in even positions are multiplied by 2 (subtracting 9 if the result exceeds 9). The total sum must be divisible by 10.
What do the digits of an Italian VAT number mean?
The first 7 digits identify the taxpayer (sequential number), digits 8-10 identify the provincial office code of the Revenue Agency that issued the VAT number, and the last digit is the check character.
Does this tool verify if the VAT number is active?
No, this tool only verifies the formal correctness of the number through the validation algorithm. To verify whether a VAT number is actually active and who it belongs to, you need to consult the Revenue Agency's VIES service or the European VIES system.
Does the tool work for foreign VAT numbers?
No, this tool is specific to Italian VAT numbers (11 digits). For validating VAT numbers from other European countries, the European Commission's VIES system is recommended.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads on the page are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From the ads on the page, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
