How to fix BR-CO-09
The Seller VAT identifier (BT-31), the Seller tax representative VAT identifier (BT-63) and the Buyer VAT identifier (BT-48) shall have a prefix in accordance with ISO code ISO 3166-1 alpha-2 by which the country of issue may be identified. Nevertheless, Greece may use the prefix 'EL'.
What this rule checks
A VAT identifier is missing the two-letter country prefix or uses an invalid one. VAT numbers must start with an ISO 3166-1 alpha-2 country code (e.g., DE, NL, FR), except Greece which uses EL instead of GR.
