🇮🇹 Validate FatturaPA Invoices for Italy

FatturaPA is Italy's mandatory electronic invoice format. Every invoice — B2B, B2C, and B2G — must be transmitted as a FatturaPA XML file through the SDI (Sistema di Interscambio), Italy's government clearance platform.

The Codice Destinatario is the recipient routing code. For public administration (PA) invoices it's a 6-character IPA office code. For private parties it's a 7-character SDI channel code, or "0000000" if the recipient uses PEC email instead.

Error 00400 occurs when an invoice line has a zero VAT rate but the Natura field is missing. Italian tax law requires a Natura code (N1–N7) to explain why VAT is not applied — for example, N4 for exempt transactions or N2.2 for non-subject operations.

Digital signature (CAdES or XAdES) was previously required but is now optional for B2B/B2C invoices sent through accredited intermediaries. B2G invoices to Pubblica Amministrazione may still require a qualified electronic signature.
