The concept of the Global Trade Item Number (GTIN) emerged from the need to standardize product identification globally. Initially, companies used different coding systems, making cross-border trade cumbersome. The GTIN standard, developed by GS1, integrates several widely used numbering formats like the European Article Number (EAN) and the Universal Product Code (UPC).
Types/Categories
GTINs are classified into four primary types based on their length:
- GTIN-8: 8 digits, typically used for small items.
- GTIN-12: 12 digits, also known as the UPC (Universal Product Code), predominantly used in North America.
- GTIN-13: 13 digits, commonly referred to as the EAN (European Article Number), used internationally.
- GTIN-14: 14 digits, used for higher-level packaging such as cases and pallets.
Key Events
- 1973: The establishment of the UPC by the Uniform Code Council (UCC) in North America.
- 1977: Introduction of the EAN system in Europe.
- 1990: GS1 was formed to oversee global trade standards, including GTIN.
- 2005: The GTIN becomes the overarching standard, incorporating EAN, UPC, and other codes.
Detailed Explanations
Mathematical Formulas/Models
GTIN-13 Check Digit Calculation
To validate a GTIN-13, the check digit is calculated using a modulo operation:
- Sum the values of all odd-positioned digits.
- Sum the values of all even-positioned digits and multiply by 3.
- Add the results of step 1 and step 2.
- The check digit is the number that, when added to the result, makes it a multiple of 10.
Example:
For GTIN 400638133393 (without check digit):
- Odd positions: 4+0+6+8+3+9 = 30
- Even positions: (0+6+3+1+3+3) * 3 = 48
- Sum: 30 + 48 = 78
- Check digit: 80 - 78 = 2
The GTIN-13 is 4006381333932.

Importance and Applicability
GTINs play a crucial role in:
- Retail: Ensuring product identification and inventory management.
- Supply Chain: Streamlining logistics and reducing errors.
- E-commerce: Facilitating product listings and integrations across platforms.
Examples
- Supermarkets: Scanning GTINs at checkout.
- Online stores: Identifying products listed on Amazon and eBay.
- Pharmaceuticals: Tracking medications through unique GTINs.
Considerations
- Accuracy: Ensure proper GTIN assignment to avoid misidentification.
- Updates: Regularly update GTINs when product packaging changes.
- Compliance: Adhere to GS1 standards.
Related Terms with Definitions
- GS1: An organization that develops and maintains global standards for business communication.
- Barcode: A visual representation of a GTIN.
- SKU: Stock Keeping Unit, an internal identifier used by companies.
Comparisons
- GTIN vs. SKU: GTIN is a standardized global identifier, whereas SKU is an internal identifier unique to a company.
- EAN vs. UPC: EAN is used internationally with 13 digits, whereas UPC is used predominantly in North America with 12 digits.
Interesting Facts
- Over 6 billion barcodes are scanned daily worldwide.
- The first product scanned using a UPC barcode was a pack of Wrigley’s gum in 1974.
Inspirational Stories
The implementation of GTINs in large retailers like Walmart and Tesco has revolutionized inventory management, reducing shrinkage and improving customer satisfaction.

FAQs
Q: How do I get a GTIN for my product?
A: Contact GS1 to obtain a GTIN for your products.
Q: Can I use a GTIN for digital products?
A: Yes, GTINs can be used for both physical and digital products.
Q: Is GTIN the same as a barcode?
A: No, GTIN is the numerical identifier, whereas a barcode is the graphical representation of that identifier.
