What does GR-R-006 mean? Greek Suppliers must provide the VAT number of the buyer, if the buyer is Greek

Why did my invoice fail GR-R-006?

When a Greek supplier invoices a Greek buyer, the invoice must contain the buyer's VAT number. This Peppol BIS 3.0 Greek country rule guarantees that domestic Greek transactions carry the buyer's tax identification, carried in UBL under cac:AccountingCustomerParty/cac:Party/cac:PartyTaxScheme/cbc:CompanyID.

Official rule text

Greek Suppliers must provide the VAT number of the buyer, if the buyer is Greek

Common causes

• Buyer VAT number (PartyTaxScheme/CompanyID) omitted for a domestic Greek buyer
• VAT number placed only in PartyIdentification instead of PartyTaxScheme
• Buyer country set to GR but the tax registration left empty
