What is UBL-CR-229?
UBL-CR-229 is a fatal validation rule defined in the UBL 2.1 specification. It validates the Name 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 will be rejected by PEPPOL/EN16931 validators. Safe to remove - these elements are explicitly prohibited in EN16931 and contain no required business data.
UBL-CR-229 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.
