VAT number corretto?

If you trade B2B with Italian suppliers or customers, you may ask: VAT number corretto? — is this VAT number correct? Before you approve an invoice, apply zero-rated VAT, or release payment, you need to confirm the registration is real and currently active. A free online VIES lookup answers that question in seconds.

What does “VAT number corretto” mean?

In Italian business, Partita IVA is the VAT registration number assigned to companies and professionals registered for IVA (Imposta sul Valore Aggiunto). When someone asks whether a VAT number is correct, they usually mean two things: does the format look valid, and is the registration currently active in the official tax registry? Only a live lookup confirms the second — format checks alone cannot tell you if a number was cancelled or never issued.

Italian VAT number format

Italian VAT numbers use the prefix IT followed by 11 digits — for example IT12345678901. The number should appear on fatture (tax invoices) and official Agenzia delle Entrate correspondence. If the IT prefix is missing, the length is wrong, or the supplier is unclear about their registration, run a verify Italian VAT number lookup before you rely on it. EU prefix rules for all member states are in EU VAT numbers explained.

How to check if an Italian VAT number is correct

Italy is an EU member state, so Partita IVA verification runs through the European Commission's VIES system. Enter the full number including the IT prefix into a VIES-connected tool. The query routes to Italy's tax authority and returns valid or invalid status plus the registered business name and address where available.
