Navigating the complexities of global commerce presents a formidable challenge, with businesses facing the daunting task of tracking countless products across vast supply chains. Misidentification and inefficiencies escalate costs and erode trust in the marketplace.
The solution to this pervasive issue lies in adopting the Global Trade Item Number (GTIN). GTIN is a standardised identifier that ensures every product can be uniquely recognised and tracked worldwide. They are instrumental in streamlining product tracking, inventory management, and sales processes, not just locally but on a global scale.
In this article, we’ll dive deep into the world of GTIN, unravelling its essence and significance in today’s global market. We’ll cover the different types of GTINs, delve into their operational mechanics, and guide you through creating and printing these crucial identifiers. Finally, we’ll tackle some frequently asked questions to clear up any uncertainties, ensuring you walk away with a comprehensive understanding of GTIN and its pivotal role in commerce.
So, without further ado, let’s get started!
The Global Trade Item Number, short for GTIN, is a unique numerical identifier for products and services used in business worldwide. This code is integral to various business processes, including inventory management, point-of-sale operations, and online product listings.
Adopting GTIN enables businesses to retrieve predefined information and track and manage products precisely, reducing data discrepancies and improving data quality across various markets and platforms. Additionally, GTINs streamline product recalls and compliance with regulatory standards, allowing businesses to address safety concerns and meet legal obligations quickly.
The development and standardisation of GTIN are overseen by GS1, a leading global organisation dedicated to designing and implementing universal standards in the supply chain. This ensures that GTINs maintain a consistent format and function effectively across international borders, reinforcing their value as a universal product identification and management tool.
A GTIN barcode is a visual representation of the Global Trade Item Number, encoded in a format that can be scanned electronically. This barcode is a gateway to a wealth of product information, including its origin, type, and unique identity. By embedding the GTIN within a barcode, businesses enable automated systems, such as scanners at checkout counters and inventory management tools, to quickly and accurately identify products.
The beauty of a GTIN barcode lies in its universal applicability. Whether it’s a book, clothing, or a grocery item, the GTIN barcode ensures that every product can be globally recognised and tracked. This streamlines the sales and inventory processes and enhances the accuracy of transactions in both physical and digital marketplaces.
GTIN barcodes come in various formats, including the widely recognised UPC (Universal Product Code) in North America, the EAN (European Article Number) in Europe, and other regional variants.
Despite these differences, the core purpose remains the same: to provide a standardised method for product identification that supports efficient supply chain management worldwide.

GTIN becomes crucial in businesses owing to a multitude of factors. Their invaluable contribution in helping with your business is evident from the following cases:
GTINs are a universal language for product identification, which is crucial for global commerce. They ensure that every product can be uniquely identified anywhere in the world, regardless of where it was made or is being sold.
This global standardisation simplifies international trade, allowing products to move seamlessly across borders. By adhering to a single system, businesses can efficiently communicate product information with partners, distributors, and retailers worldwide. This eliminates confusion and enhances operational efficiency.
GTINs dramatically streamline the entire supply chain, from manufacturing through to distribution. They enable precise tracking of products, facilitating efficient inventory management and reducing the likelihood of errors.
This efficiency is crucial for optimising logistics operations, ensuring that products are in the right place at the right time. By providing a clear and consistent method for identifying products, GTINs help to minimise delays, prevent stockouts, and reduce excess inventory.
GTINs are integral to both physical retail and online e-commerce platforms, simplifying transactions and product listings.
In retail stores, GTINs facilitate quick and accurate checkout processes, while in e-commerce, they enable efficient listing and cataloguing of products on various platforms. This uniform identification system helps retailers manage their product data effectively, ensuring customers receive accurate information.
For online sellers, GTINs improve the searchability and visibility of products, enhancing the customer shopping experience.
GTINs are critical in meeting regulatory requirements across various industries, ensuring products are tracked and traced for safety and compliance purposes. Governments and regulatory bodies often mandate the use of GTINs for specific products to streamline recalls, monitor distribution, and enhance public safety.
In healthcare, for example, GTINs are essential for tracking pharmaceuticals and medical devices, helping to prevent counterfeit products from entering the supply chain. Similarly, GTINs facilitate traceability from farm to table in the food industry, crucial for addressing food safety concerns.
GTINs enhance data management and analytics, enabling businesses to unify product information for better decision-making. Companies can efficiently analyse trends, manage inventory, and understand consumer behaviour across markets by standardising data collection.
This leads to optimised operations, strategic planning, and innovation. GTINs are pivotal in transforming product data into actionable insights, offering a competitive edge through informed decisions and improved market responsiveness.
The structure of a GTIN is methodical. Thus, every digit of the number has a particular specific meaning attached to it. This systematic approach ensures that each GTIN is unique and error-free, crucial for reliable product identification and tracking.
Each GTIN consists of three things, a company prefix assigned by GS1, an item reference number specific to each product, and a check digit for validation. Let’s take a look at each GTIN component in detail.
The Company Prefix is a unique sequence of numbers assigned by GS1 to each member company. A member company is defined as any business that joins GS1 to use its services, including utilising the Global Trade Item Number system. This company prefix acts as a global identifier, distinguishing the company across international markets.
GS1 ensures that each member company is assigned a distinct Company Prefix, eliminating any possibility of duplication. This exclusivity guarantees that no two companies share the same prefix, thereby maintaining the uniqueness of product identifiers across the globe.
The length of the Company Prefix is designed to be flexible, varying according to the number of items a company intends to identify. This variability allows for both flexibility and scalability in product identification, accommodating businesses of all sizes and their diverse range of products. Through this system, GS1 facilitates a structured and efficient approach to global product identification, underpinning the seamless operation of the global supply chain.
Obtaining a Company Prefix is the first step for a business to start using Global Trade Item Numbers. Here’s a detailed look at how to get a Company Prefix.
When purchasing a GS1 Company Prefix, consider your current and future product range, as the cost depends on the number of GTINs it can generate. Each unique product variation, encompassing differences in colour, size, or any other distinguishing feature, necessitates its own GTIN to ensure precise identification.
To clarify with a concrete example, consider a T-shirt that is available in four colours (red, blue, green, black) and four sizes (S, M, L, XL). This scenario demands a total of 16 unique GTINs, one for each specific combination of colour and size. For instance, a red T-shirt in a small size will have a different GTIN from a red T-shirt in a medium size, and so on for each colour across all sizes. This meticulous approach ensures that every possible variant of the T-shirt is assigned a unique identifier, facilitating precise tracking and management from the manufacturing process all the way to retail distribution.
This system underscores the importance of planning for the full range of your product variations, including those you may introduce in the future. By doing so, you can ensure that your GS1 Company Prefix provides sufficient capacity for generating GTINs, thereby streamlining your inventory management and enhancing the efficiency of your supply chain operations.
The item reference is a set of numbers that uniquely identify a product within a company’s product range. This identifier is determined internally by the company and is positioned after the GS1-issued Company Prefix.
The allocation of the item reference is directly influenced by the length of the Company Prefix. For instance, in a 13-digit GTIN framework, a company with a 5-digit prefix is left with 7 digits to assign to its product numbers (calculated as 13 – 5 prefix digits – 1 check digit = 7). Conversely, a company with a 4-digit prefix would have 8 digits available for product identification, ensuring the GTIN maintains a consistent total length.
The Check Digit is a single numeric digit at the end of the GTIN, ensuring the GTIN number’s overall integrity and accuracy. It is calculated through a specific yet straightforward algorithm, and it sums and manipulates the preceding digits in a set pattern (More on this later).
If an error occurs during data entry or scanning, a mismatch in the Check Digit highlights the mistake. This straightforward but powerful system plays a vital role in global supply chains, preventing small errors in product identification from causing major logistical issues.
GTIN is of four types.
GTIN-8 is a compact version of the Global Trade Item Number designed for smaller items, such as chewing gum and cigarette packets, that cannot accommodate larger barcodes. As the name suggests, GTIN-6 consists of an 8-digit numerical code.
The structure of GTIN-8 includes a 2- or 3-digit GS1 prefix (indicating the country of the issuing organisation), a 4- or 5-digit item reference, and a single check digit to ensure the number is correctly composed.
GTIN-12 is a 12-digit Global Trade Item Number primarily used in North America, especially for retail items. It’s widely recognised under its former name, UPC (Universal Product Code).
The structure of GTIN-12 includes a 1- or 2-digit GS1 prefix (indicating the country of the issuing organisation), a 5- or 6-digit company number, a 5-digit product number, and a single check digit to verify the accuracy of the entire number.
GTIN-13, commonly known as the European Article Number (EAN-13), is a 13-digit Global Trade Item Number used worldwide for marking products often sold at retail point of sale.
Out of 13 digits, the first 2-3 digits are the GS1 prefix assigned to national GS1 Member Organizations, followed by a sequence of 4-5 digits representing the company number, a 5-digit product reference, and ending with a single check digit for error detection.
GTIN-14 is the most extensive format in the Global Trade Item Number system, designed to accommodate the needs of various packaging levels. This 14-digit number is primarily used for cases, cartons, or pallets of products, facilitating efficient logistics and supply chain management.
The structure of GTIN-14 includes a leading “Indicator Digit” that specifies the packaging hierarchy (e.g., a single item, a case, or a pallet), followed by a GTIN-13 number. The GTIN-13 portion comprises a GS1 prefix, a company number, a product number, and a check digit. The initial digit, the Indicator, plays a crucial role in differentiating between items and their bulk packaging, allowing businesses to streamline inventory and shipping processes.
GTIN-14 is essential for wholesalers, retailers, and manufacturers dealing with bulk shipments and managing products at different packaging levels. It ensures that each packaging level is uniquely identified, improving accuracy in order tracking, stock management, and distribution.
The Global Trade Item Number (GTIN) system functions through a structured, technical process that ensures every product can be uniquely identified globally. Here’s a closer look at the technical workings behind GTIN:
To create a GTIN number for your business, you need to follow these simple steps:
First, join GS to start creating GTINs for your products. This gives you access to the GS1 system and the ability to generate unique product identifiers.
After joining GS1, you’ll receive a GS1 Company Prefix. This unique number identifies your company in the global supply chain. The length of your prefix varies based on how many products you plan to identify, allowing for a range of product numbers to be assigned under your company’s umbrella.
With your GS1 Company Prefix, assign a unique product number to each item or variant you sell. This step is crucial for differentiating your products from others in the global marketplace. The combination of your company prefix and this product number will form the basis of your GTIN, ensuring each product has a unique identifier.
Select the appropriate GTIN format for your product based on its size, packaging, and where it will be sold.
Options include GTIN-8 for smaller items, GTIN-12 primarily for North American products, GTIN-13 for international products, and GTIN-14 for items sold in bulk or in varying packaging levels.
This choice determines how your product will be identified and tracked globally.
The last step in creating your GTIN is calculating the check digit. This is the final digit of your GTIN, ensuring the number is valid and correctly composed. The check digit is calculated using a specific formula based on the preceding digits in your GTIN. This critical step helps prevent errors in the barcode scanning process, ensuring accurate product identification.
The formula to calculate the check digit for a GTIN is based on the “Modulo 10” or “Luhn” algorithm. Here’s a simplified explanation of how it works:
Here’s an example of how to create the same:
For a GTIN-12 with the digits 12345678901X (where X is the check digit we want to calculate):
This formula ensures that the GTIN is valid and helps detect errors during scanning.
Once you have your complete GTIN, including the check digit, the next step is to generate a barcode that visually represents this number and serves as a data carrier. Here’s how to do it:

Designing your barcode right is always essential. Follow GS1 standards to make sure it scans every time:
Quiet zones are the clear spaces on either side of your barcode. Think of them as margins that tell the scanner, “Hey, the barcode starts here and ends here.”
The rule of thumb is to have at least the width of two narrow bars on each side of your barcode. This might vary slightly depending on the barcode type, but it’s a good general guideline.
Without enough quiet zones, your product could face scanning issues, leading to delays and frustration at checkouts or during inventory checks.
Where you place your barcode on the product packaging is just as important as its design. A well-placed barcode ensures easy and reliable scanning. Here’s what to consider:

The Global Trade Item Number (GTIN) framework is central to the ecosystem of barcodes, providing a universal structure for uniquely identifying products.
Within this broad framework, specific barcode standards such as EAN (European Article Number) and UPC (Universal Product Code) address particular needs and regional preferences, each with its distinct characteristics and applications.
Within the GTIN family, the European Article Number (EAN) is a prominent standard primarily utilised for retail products outside of North America. Functioning as a GTIN-13, the EAN includes a country code that identifies the product’s country of origin and its manufacturer. This detail is pivotal for companies operating internationally, as it ensures their products are easily recognised and processed within global supply chains.
For a deeper understanding of the relationship between EAN and GTIN, consider exploring our detailed article on EAN vs. GTIN.
Conversely, the Universal Product Code (UPC), or GTIN-12, is specifically designed to meet the demands of the North American market. UPCs are known for their streamlined barcode format, which supports rapid scanning at retail checkout points, making them particularly suited for items with limited packaging configurations.
Despite the regional focus of UPCs, they are fully integrated into the broader GTIN framework. This integration guarantees that products labelled with UPCs are identifiable and traceable globally, bridging the gap between local market needs and international product identification standards.
