How to get an invoice with your tax details

An Italian VAT number, a codice fiscale, a recipient and a complete address, province included. With the box ticked the form asks for each:

• VAT number — IT and 11 digits, or the 11 digits alone. A wrong check digit is refused as you type.
• Codice fiscale — filled in with your VAT number's 11 digits, and editable: "For a company it is the VAT number's digits. Sole trader or freelancer? Enter your personal codice fiscale." A personal one has 16 characters.
• Delivery — SDI code (7 letters or digits) or PEC.
• The address — Billed to, the first address line, the postal code, the city and the province.

What happens if I choose PEC instead of an SDI code?

The invoice goes to the PEC address you already registered with the Agenzia delle Entrate, so Fincanva does not ask for one: "The invoice goes to the PEC address you registered with the Agenzia delle Entrate. If you have not registered one, you will find it in your cassetto fiscale."

Can I get an electronic invoice without an Italian VAT number?

No, not for now: the details cannot be saved, and VAT number shows "For now the electronic invoice needs an Italian VAT number."

With an Italian address, the electronic invoice arrives through the Sistema di Interscambio at your SDI code, or — with PEC — at the PEC address registered with the Agenzia delle Entrate, or else in your cassetto fiscale. In every country, Invoices on Settings → Payments and invoices lists your invoices grouped by year, each with its status and a PDF.

How do I correct my billing details or an invoice?

Change the details in Billing address or Tax details and select that section's Save: the change applies to invoices issued after you save it. An invoice already issued is not rewritten — to correct one, contact Fincanva support.

In three places, until the missing detail is filled in and saved — there is nothing to dismiss:

• Your account avatar carries a small dot, and the account menu adds a Payments and invoices row reading "Something is missing for the electronic invoice".
• The list of settings shows a dot beside Payments and invoices.
• The top of Settings → Payments and invoices shows "Your electronic invoice is missing: …", naming the missing details, with Complete the details, which takes you to Billing address and Tax details with the missing details already marked.

Because it fails a check the form makes as you type; each message names which.

"This VAT number is not valid: check the digits."

The last digit of the Italian VAT number does not match the other ten. Check it against your VAT registration.

"Enter a valid VAT number"

The number lacks your address country's format, or carries another country's prefix. Check Country, then the number.

The SDI code "is reserved for customers abroad."

Seven letters X is the code for customers outside Italy, refused with an Italian VAT number; the message repeats it. Enter your own 7-character code, or choose PEC.

"The SDI code has 7 letters or digits."

Check the code and type it again, or choose PEC.

"The codice fiscale has 11 digits or 16 characters."

A company's is its VAT number's 11 digits; a personal one has 16 characters.

"This codice fiscale is not valid: check the characters."

The length is right, but the check character does not match the rest. Check it against your tax documents.

"Enter the province."

An Italian billing address needs its province. Fill in Province and save again.
