What is a GTIN barcode?
EAN-13 is the most widely used product barcode worldwide and carries a 13-digit GTIN. It uniquely identifies items at the checkout and along the supply chain.
The last digit is a check digit that Barcode Studio calculates automatically, so you avoid typos and get a standards-compliant, scannable code.

Tips for clean printing & scanning
- Keep enough quiet zone left and right (at least 10× the module width) so checkout scanners trigger reliably.
