Use GTINs
About GTINs
A Global Trade Item Number (GTIN) is the source of truth and used to identify trade items and products throughout the supply chain, primarily within barcodes. GTIN is a term used to describe multiple families of product identification numbers such as:
Universal Product Identifiers (UPC-E, UPC-A, GTIN-12): A 12-digit number used primarily in North America.
GTIN-14 (EAN/UCC-14 or ITF-14): A 14-digit number used to identify trade items at various packaging levels.
Data associated with a GTIN typically includes all of the details required to catalog a physical good including item name, image, description, brand, etc.
Manufacturers and brands register their product information to databases such as Gs1 to ensure that retail businesses have access to complete and accurate information about products for sale. Learn more about GTINs.
Before you begin
To use GTINs, you need access to Square Point of Sale, the Square Retail POS app, or Square Dashboard.
Once a GTIN is associated with an item, you can add the item to your customer’s cart by scanning the barcode with a compatible barcode scanner or your iOS device’s camera. Learn how to add items to a cart by scanning a GTIN.
