Application Identifier 241 is used for the customer’s additional product identification. It may be used in situations where the customer has assigned their own internal number to a product, even though the product is already identified by a GTIN. Companies are advised not to use AI 241 unless strictly necessary, as AI 241 should be regarded as a temporary solution until GTIN product numbers are fully implemented.
AI 241 does not replace AI 01 (GTIN) as the primary identification of the product. AI 241 must always be used together with AI 01 or AI 02.
