What is a GTIN-14?
GTIN-14 is a 14-digit Global Trade Item Number used for trade item groupings such as cases and packaging. It is common in logistics and business-to-business product data rather than at a retail point of sale.

Checks happen locally. We do not confirm product ownership or product data.This validator checks
- The number has exactly 14 digits.
- The number contains digits only after spaces and hyphens are removed.
- The final digit matches the GS1 modulo-10 check digit.
How does GTIN-14 relate to packaging?
A GTIN-14 can identify a grouping of products, for example a case containing multiple consumer units. It is often carried in an ITF-14 or GS1-128 barcode when the outer case is scanned in a logistics workflow.
What does this GTIN-14 check verify?
The validator checks the 14-digit length and the final GS1 modulo-10 check digit. It does not determine the packaging level, the case quantity, or whether the number was assigned to a real trade item.
Frequently asked questions
Is GTIN-14 used on retail products?
GTIN-14 is generally used for cases and packaging. Consumer units scanned at retail commonly use GTIN-8, GTIN-12, or GTIN-13.
Is a GTIN-14 simply an EAN-13 with a zero in front?
No. Database representations may use leading zeroes for fixed-length storage, but a GTIN-14 is its own 14-digit identifier and must have a correctly calculated check digit.
