GS1 QR Code (Digital Link) (GS1-QR)
QR Code encoding a GS1 Digital Link standard URI, allowing single 2D codes to support point-of-sale scanning, consumer transparency, and DSCSA verification.
Governing Specification: GS1 Digital Link Standard 1.2 / ISO/IEC 18004
Data Format & Required Fields
Encodes structured web URIs following the GS1 Digital Link grammar (e.g. https://domain.com/01/{gtin}/10/{lot}/21/{serial}?17={exp}).
Allowed Character SetValid GS1 Digital Link HTTP/HTTPS URI.
Payload Length Rule Between 15 and 500 characters
Required GS1 Structure Encodes standardized GS1 Application Identifiers (AIs). Unit-level and master packaging require primary identification (e.g. GTIN-14 or SSCC-18) combined with variable batch and serialization attributes for supply chain verification.
Check Digit / Checksum Rule Requires a verified modulo-10 check digit to prevent scanner misreads and data transposition errors.
