What is GTIN?

A Global Trade Item Number (GTIN) is a unique code used to identify products globally, ensuring that each item can be distinguished from others in the market. Much like a product passport, it prevents duplication and supports efficient inventory management, tracking, and checkout processes.

GTINs are commonly embedded in barcodes, such as the GS1 barcode, on product packaging. This allows businesses to scan and manage products easily, whether at retail stores or on online platforms.

The GTIN full form is Global Trade Item Number, and it plays a vital role in enabling smooth product identification across international markets. By standardising product data, GTINs help businesses manage inventory more effectively and simplify sales, tracking, and distribution worldwide.

What is the purpose of a GTIN?

The primary purpose of a GTIN is to uniquely identify products, ensuring seamless operations in global trade and commerce. By providing a standardised identification system, GTINs facilitate accurate and efficient tracking, inventory management, and sales processes. They help businesses and retailers minimise errors in product identification, reduce supply chain disruptions, and enhance data accuracy. Additionally, GTINs support regulatory compliance and enable interoperability across different systems and platforms. In eCommerce, GTINs play a vital role in product listing, helping customers find the exact items they need.  Learn about assets that businesses must manage effectively to ensure GTIN implementation success.Overall, GTINs streamline the entire product lifecycle, from production to the end consumer, enhancing operational efficiency and customer satisfaction.

Types of GTIN

There are various types of GTINs, each serving different product identification needs. Understanding these types is essential for businesses to choose the correct GTIN for their products. Entrepreneurship in global markets often involves understanding and adopting technologies like GTINs for product identification and inventory management.

GTIN-13

GTIN-13 is the most commonly used GTIN format, consisting of 13 digits. It is widely used in Europe and other regions and is often represented as an EAN-13 barcode. Cost of capital can be impacted by how effectively a company manages its product and inventory systems, such as GTIN integration, to reduce errors and improve operational efficiency.

GTIN-8

GTIN-8 is an 8-digit identifier used for smaller items with limited space for a barcode. It is mainly used in retail environments where space constraints exist.

GTIN-12

GTIN-12, also known as the Universal Product Code (UPC), consists of 12 digits and is predominantly used in North America. It is commonly seen in retail products and packaged goods.

GTIN-14

GTIN-14 is a 14-digit identifier used primarily for identifying trade items at various packaging levels, such as cartons and pallets. It is useful for managing inventory in warehouses and distribution centres.

Structure of GTIN

Global Trade Item Number barcodes are available in four formats, with lengths of 8, 12, 13, or 14 digits. Each type is designed for global use, depending on the product and its application.

GTIN 12

A GTIN 12 consists of 12 digits and is mainly used in North America. It is designed for scanning at the point of sale and is commonly associated with UPC codes. It is the only GTIN format that can be encoded in a UPC A barcode.

GTIN 14

A GTIN 14 contains 14 digits and is typically used to identify grouped trade items, such as cartons or bulk packaging. It is not intended for point of sale scanning and does not begin with a zero as the first digit.

GTIN 8

A GTIN 8 includes 8 digits and is generally used for smaller products, especially in markets outside North America. It is suitable for point of sale scanning where packaging space is limited.

GTIN 13

A GTIN 13 is 13 digits long and is widely used outside North America. It is designed for point-of-sale scanning and is equivalent to the EAN system, being the only GTIN format that can be encoded in an EAN 13 barcode.

Why are GTINs important for eCommerce?

The Global Trade Item Number (GTIN) is important in modern eCommerce as it provides a universal way to identify products across the global supply chain. Its role in eCommerce is crucial because of several benefits that help improve the efficiency, reliability, and growth of online business operations. Here is why GTINs are so important for eCommerce:


  • Drives eCommerce: GTINs play a key role in the global movement of trade items and the information needed for eCommerce. By standardising how products are identified, GTINs make it easier to find products on online platforms. This helps businesses list and sell products across various eCommerce sites and marketplaces, allowing them to reach a larger audience without needing multiple identifiers.
  • Enhances compatibility across business sectors: Using GTINs helps build trust among businesses in all sectors. This trust comes from the fact that GTINs ensure products are identified in the same way, no matter the industry or market. Such compatibility is vital for different systems to work together in a global eCommerce environment.
  • Facilitates accuracy in supply chain operations: Using GTINs at important stages in the supply chain, such as shipping, receiving, and in point-of-sale systems, helps maintain accurate stock levels and ensures timely order replenishment. This accuracy is key in eCommerce, where customers expect products to be available and delivered quickly.
  • Leverages the GS1 Global Data Synchronisation Network (GDSN): GTINs allow businesses to use the GS1 Global Data Synchronisation Network (GDSN), which helps manage product information across the supply chain. The GDSN makes sure all trading partners have the same and up-to-date product details, improving data accuracy, operational efficiency, and reducing costs related to data errors.
  • Simplifies supply chain management: GTINs make communication between supply chain partners easier by providing a unique identifier for each product. This simplification leads to better management of product and information flow, reducing errors and making the supply chain more agile. In fast-paced eCommerce, this efficiency is crucial to meet customer demand and stay competitive.
  • Improves data quality: GTINs help improve data quality in the supply chain. By ensuring consistent product information among all partners, GTINs help eliminate issues like incorrect product shipments or listings. High-quality data is essential for making better business decisions and offering accurate product information, which leads to better customer experiences and loyalty.

How do you get a GTIN number?

  • Register with GS1: Begin by registering your business with GS1, the organisation responsible for issuing GTINs.
  • Obtain a GS1 company prefix: Upon registration, you will receive a unique GS1 Company Prefix, which forms the basis of your GTINs.
  • Assign GTINs to products: Use the GS1 Company Prefix to create unique GTINs for each of your products.
  • Ensure correct formatting: Verify that your GTINs adhere to the correct format (e.g., GTIN-13, GTIN-8, etc.).
  • Label products with GTINs: Apply the GTINs to your product packaging using barcodes or QR codes.
  • Maintain records: Keep detailed records of the GTINs assigned to each product to ensure accurate tracking and inventory management.

How are GTINs used?

A GTIN can serve multiple purposes, with two key roles in business operations.

  • Its primary function is physical identification, where it is encoded into barcodes and scanned at points of sale, care, or during distribution. This enables accurate and efficient data capture across the supply chain
  • Its second role is in e commerce, where it helps ensure that the correct product is listed, picked, packed, and delivered. Since customers cannot physically inspect items online, GTINs play a critical role in maintaining accuracy and trust

In addition, GTINs are used to access standardised product information such as pricing and product details. They also support data exchange between trading partners through systems like the GS1 Global Data Synchronization Network (GDSN), Electronic Data Interchange (EDI), and GS1 XML, facilitating transactions such as purchase orders, invoices, and shipping notifications

Conclusion

GTINs are indispensable tools for businesses, enhancing product identification, tracking, and management across various sectors. Their adoption ensures efficient operations, regulatory compliance, and improved customer satisfaction. For eCommerce, GTINs are particularly vital, ensuring accurate product listings and streamlined shopping experiences. Obtaining and using GTINs correctly involves understanding their structure and application, which is crucial for maintaining effective inventory and supply chain management. As businesses seek growth and efficiency, leveraging GTINs and understanding their importance can significantly impact their success.
