What is PEPPOL-EN16931-R010?

PEPPOL-EN16931-R010 is a fatal validation rule defined in the Peppol BIS 3.0 specification. It validates the Name element under Party > PartyName in the UBL invoice XML.

When this rule fires, the invoice is non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach the buyer.

Why This Error Matters

Invoice will be rejected by PEPPOL validation. Electronic address is mandatory for PEPPOL network routing.

PEPPOL-EN16931-R010 is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.
