GS1 Standards & Digital Product Passport Data Requirements

GS1 Digital Link standards underpin the DPP data architecture. GTINs, data carriers, resolver infrastructure, and structured product information formats form the backbone of DPP compliance.

Data Carrier Standards

GS1 specifies QR codes as the primary data carrier for DPPs, encoding GTINs and serial numbers in a web-resolvable URI format that links to product data endpoints.
