FatturaPA is Italy's mandatory electronic invoice format, processed through the Sistema di Interscambio (SDI). All B2B, B2C, and B2G invoices in Italy must be transmitted as FatturaPA XML files. The SDI validates each invoice against over 200 checks before delivering it to the recipient.

Validator vs Access Point vs ERP Built-in

Invoice Navigator

Pre-submission check against SDI rules. Catches Codice Destinatario, VAT format, and XML schema errors before you send. Provides fix guidance in plain language.

Access Point

SDI rejects non-compliant invoices with technical error codes (e.g. 00305, 00311). Rejection means re-issuing and re-transmitting — no preview available.

ERP Built-in

Software like Fatture in Cloud or Aruba generate XML but don't always validate against all SDI checks. Codice Destinatario and Natura IVA errors slip through.

FatturaPA FAQ

What is FatturaPA?
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.
What is the Codice Destinatario?
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.
What does SDI error 00400 mean?
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.
Do I need to sign my FatturaPA?
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.
Is this validator free?
Yes. You can validate up to 10 invoices per month for free. No signup required for basic validation.
