What is GS1 Digital Link?
GS1 Digital Link is a standard that embeds GS1 identifiers such as GTIN, GLN or SSCC into web addresses. This lets one 2D code both identify a product and connect it to online information.
The difference from a normal QR code is semantics: the URL contains structured GS1 keys. Systems can extract the identity, resolvers can return relevant content and humans still land on a readable web address.
Why does GS1 Digital Link matter for DPP?
A Digital Product Passport needs a stable entry point. GS1 Digital Link connects that entry point with established retail and supply chain identifiers instead of creating isolated QR codes for every use case.
This is especially useful when the same physical code should serve multiple roles: consumers see care or sustainability information, retailers use master data, recyclers receive dismantling instructions and authorities verify conformity data.
- One data carrier can support multiple information targets.
- Existing GTIN and supply chain processes remain usable.
- Target content can be updated without reprinting packaging or labels.
- Resolvers can return different answers by language, role or data need.
What is a resolver?
A resolver is a service that derives the relevant information or service from a GS1 Digital Link. It can point to a consumer page, machine API, safety data sheet or protected product passport endpoint.
For DPP projects, the resolver is where technical architecture and governance meet. It must stay available, separate access cleanly and manage changes so product information remains current.
How should companies adopt GS1 Digital Link?
Adoption starts with identification strategy. Companies need to decide whether the product passport lives at model, batch, serial-number or individual-unit level and which GS1 keys already exist in their systems.
Then come URL structure, resolver rules, roles and content. Teams that make these decisions early avoid later reprints and can use the same code for retail, customer communication and compliance.
