What does the first two digits of a NIIN represent?

The first two digits of a National Item Identification Number (NIIN) represent the National Codification Bureau (NCB) code, which indicates the country responsible for the item’s identification. The NIIN is a 13-digit number where the first two digits identify the NCB; this is crucial for international logistics and inventory management, as it standardizes the identification of items across different nations. Knowing the NCB code allows personnel to quickly ascertain the logistics and supply chain information related to the particular item, ensuring accuracy in item tracking and inventory.
