What does GR-S-011 mean? Greek suppliers must provide their Seller Tax Registration Number, prefixed by the country code

Why did my invoice fail GR-S-011?

Greek suppliers must provide their Seller Tax Registration Number prefixed by the country code. In UBL this is the seller's cac:PartyTaxScheme/cbc:CompanyID; the rule requires the value to start with the country prefix so the tax registration is unambiguous across borders.

Official rule text

Greek suppliers must provide their Seller Tax Registration Number, prefixed by the country code

Common causes

• VAT/tax number given without the country code prefix (e.g. 123456789 instead of EL123456789)
• Seller PartyTaxScheme/CompanyID missing entirely
• Wrong prefix used for a Greek registration

How do I fix it?

<cac:PartyTaxScheme>
  <cbc:CompanyID>EL123456789</cbc:CompanyID>
  <cac:TaxScheme><cbc:ID>VAT</cbc:ID></cac:TaxScheme>
</cac:PartyTaxScheme>
