What is BR-10?

BR-10 is a fatal validation rule defined in the EN 16931 specification. It validates the IdentificationCode element under PostalAddress > Country 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 rejected. Buyer address is required for delivery confirmation, tax compliance, and legal validity.

BR-10 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.
