GTIN Validator & Check Digit Calculator
Our validator works seamlessly with all major Global Trade Item Number formats – GTIN-8, GTIN-12, GTIN-13, and GTIN-14.
It checks the accuracy of your barcode numbers and instantly generates the correct check digit when required. The tool also recognises and verifies multiple barcode standards, including ISBN, ISSN, UPC, EAN, and ITF.
Whether you handle retail, manufacturing, or logistics, this ensures your product codes stay accurate, reliable, and fully compliant.
