What is BR-FR-02?
BR-FR-02 is a fatal validation rule defined in the peppol-bis-3 specification (FRA national rules). It validates the CompanyID element under Party > PartyLegalEntity 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.
Target path: XPath: /Invoice/cac:AccountingSupplierParty/cac:Party/cac:PartyLegalEntity/cbc:CompanyID[@schemeID="0009"]
Why This Error Matters
Invalid SIRET format will cause rejection by French government systems. The Luhn checksum algorithm is used to validate SIRET numbers.
BR-FR-02 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.
