What is the correct Italian VAT identifier format?

Uppercase IT followed by exactly 11 digits, with no spaces or separators — for example IT12345678903.

Is Partita IVA the same as Codice Fiscale?

No. Partita IVA is the 11-digit VAT number for businesses. Codice Fiscale is a 16-character alphanumeric identifier for individuals (or an 11-digit number for entities that matches the Partita IVA). Only Partita IVA belongs in the VAT identifier field.

Can Invoice Navigator auto-fix R047?

Yes — Invoice Navigator normalises the format (uppercase prefix, strip separators) and only escalates when the digit count is wrong, since that signals a master-data problem the customer needs to fix upstream.

Why does the invoice still get through Peppol with R047?

R047 is a warning, not a fatal rule. Peppol will route the invoice, but the Italian SDI and Italian buyers frequently reject on downstream validation.

Italian VAT identifier format warning

This is the rejection, word for word: „[PEPPOL-EN16931-R047] PEPPOL-EN16931-R047 fires when a party VAT identifier is issued by Italy but does not match the Italian Partita IVA format. The rule is a warning — the invoice can still be delivered — but many Italian buyers, the SDI exchange system, and downstream reconciliation processes will reject invoices where the VAT ID does not conform.“

The Peppol schematron checks parties whose VAT identifier scheme resolves to Italy (IT prefix on the CompanyID) and requires the identifier body to be exactly 11 numeric digits after the country prefix. The valid format is IT followed by 11 digits (e.g. IT12345678903). The rule catches common mistakes: extra spaces, hyphens, alphabetic characters, or fewer/more than 11 digits after the prefix.

What to have readyThe missing value from your purchase order, contract or bookkeeping.

What we doStrip all non-digit characters after the IT prefix; ensure exactly 11 digits remain. Reject anything that does not match.
