GTIN
GTIN (Global Trade Item Number) is a standardized number used worldwide to identify products in retail and e-commerce. Think of it as a product's unique passport number that helps track items across different stores, warehouses, and online platforms. It's like a more advanced version of a barcode system, and it's essential for businesses selling products online or in stores. When you see terms like UPC, EAN, or ISBN on products, these are actually different types of GTINs. This standardization helps businesses manage inventory, list products on marketplaces like Amazon or Walmart, and ensure customers get exactly what they ordered.
