What is GS1 Digital Link?
GS1 Digital Link is the URI syntax for representing GS1 identifiers such as GTINs, GLNs or SSCCs in web addresses. For Digital Product Passports, this matters because the same scan can carry product identity and lead to online information.
The current GS1 Digital Link URI standard is release 1.6.0, ratified in March 2025. It defines how GS1 keys are built into a web URI and how product, batch or serial-level granularity can be represented in that address.
Why does it matter for DPP and ESPR?
ESPR requires Digital Product Passports for covered product groups to be connected through a data carrier to a persistent unique product identifier. GS1 Digital Link is not a blanket EU mandate, but it is a practical open standard for companies that already use GS1 identifiers.
The boundary is important: GS1 Digital Link solves addressing and identification, not the entire product passport. Data models, access rights, evidence, versioning and regulatory fields still need to be governed separately.
How does Nulara use GS1 Digital Link?
In Nulara, GS1 Digital Link is treated as the identification and routing layer. A product can be addressed at model, batch or serial level; behind that URI sit structured product data, evidence, approvals and access levels.
This keeps the data carrier stable while the passport evolves. A QR code on packaging does not need to be reprinted for every data correction as long as the URI and resolver strategy are maintained over time.
- Use the GTIN for stable product identity and trade systems.
- Add batch or serial granularity only where passport data genuinely needs it.
- Version resolver rules, redirects and API endpoints so old data carriers keep working.
