GS1 Digital Link is emerging as the recommended URI standard for Digital Product Passport data carriers under the ESPR. Its principle: turn a GTIN identifier into a URL. As a result, a single QR code acts as both a web link to the passport (for the consumer) and a machine identifier (at the checkout, across the supply chain).
It rests on standardized foundations — ISO/IEC 15459 for identification, ISO/IEC 18004 for the QR — and fits into a stack of EPCIS 2.0 (supply-chain data exchange) + JSON-LD (machine-readable structuring).
What it changes for you
It’s the technical bridge between the physical object and its product record. A PIM that speaks GTIN + Digital Link natively is ready to feed the passport without a bolted-on layer: the URL resolves to attributes already governed in the repository. Adopting the standard early means avoiding a full re-implementation when the mandate lands.
