Application Identifier (AI) 427 specifies an ISO-based country subdivision code (e.g. provinces, states, or cantons) indicating the region of origin of the product.
The ISO country subdivision code contains up to three alphanumeric characters based on ISO 3166-2:2007.
Note: This AI applies to a grouping of products (e.g. a carton) where the products originate from the same region.
Note: The declared region of origin is the location where the product was processed or manufactured. It is the responsibility of the brand owner to determine the correct origin.
AI 427 must always be used in conjunction with a GTIN and AI 422 (which specifies the country of origin of the product).
