Global Trade Item Number (GTIN)

What is a GTIN (Global Trade Item Number)?

A Global Trade Item Number (GTIN) is a unique identifier assigned to products in the supply chain to facilitate efficient tracking and management from production to point of sale. It provides a standardized method for identifying items globally, ensuring accurate inventory control, and enabling seamless transactions between trading partners.

How to Get a GTIN Number

To obtain a GTIN, manufacturers or brand owners need to register with a GS1 Member Organization, the global standards body responsible for issuing GTINs. GS1 assigns unique identification numbers to products based on the number of items and variations. Each product variant, such as different sizes or colors, requires a unique GTIN.

How Many Digits in a GTIN Number?

A GTIN can have different formats depending on its application:

  • GTIN-12: Used primarily in North America, encoded in UPC-A format with 12 digits.
  • GTIN-13: Used globally, encoded in EAN-13 format with 13 digits.
  • GTIN-14: Used for shipping containers and pallets, encoded in ITF-14 format with 14 digits.

The digits include a company prefix, item reference, and a check digit to ensure accuracy.

GTIN vs. UPC

GTIN is a broader term that encompasses various barcode standards used worldwide, including UPC (Universal Product Code). UPC is a specific type of GTIN used predominantly in the United States and Canada, encoded in a GTIN-12 format.

What is a GTIN Exemption?

A GTIN exemption allows products that do not have a GTIN assigned to be sold on platforms like online marketplaces. These exemptions are granted under certain conditions, such as products not intended for retail sale, customized products, or items with temporary packaging variations.
