Error code PEPPOL-EN16931-CL008
The Peppol address has an unknown scheme
An electronic address (BT-34 or BT-49) must use a scheme code from the official list, such as the Belgian enterprise or VAT number schemes.
The official rule
“Electronic address identifier scheme must be from the codelist "Electronic Address Identifier Scheme"”
Official text, in the language the rule set publishes it in.
Common causes
- The customer is a private person without a Peppol ID.
- The enterprise or VAT number has a typo or is mapped to the wrong field.
- A GLN with letters was used as Peppol address.
How to fix it
- Correct the number on the customer card.
- Send private customers the invoice by email instead of via Peppol.
