What it means
When the electronic address (BT-34 for the seller, BT-49 for the buyer) uses scheme 9907, the address must be a correctly formatted Italian tax number (Codice Fiscale). It is the same format test as for scheme 0210, but applied only to the electronic address. A Codice Fiscale can have 16 letters and digits or 11 digits.
Why it matters
Peppol BIS Billing 3.0 requires electronic addresses using scheme 9907 to use the Codice Fiscale format.
How to fix it
Copy the Codice Fiscale again from the tax code card or certificate, or ask the seller or buyer for the exact number, and enter it without spaces. In your invoicing software this is the electronic address of the seller or the buyer. If you build the XML yourself, it is cbc:EndpointID with schemeID 9907.
