What is a unique identifier assigned to a specific item in inventory known as?

The unique identifier assigned to a specific item in inventory is known as the stock number. This unique designation allows for efficient tracking, management, and retrieval of inventory items within a system. Stock numbers help avoid confusion between similar items and ensure that each product can be easily identified by personnel managing the inventory.

Other terms like "inventory label," "item code," and "product tag" may relate to inventory management as well, but they are often used in broader contexts or may not always denote the specific, standardized identifier that stock numbers represent. This clarity is essential, particularly in logistics and supply chain management, where precise identification of items is critical for inventory accuracy and operational efficiency.
