The Digital Product Passport comes from the EU's Ecodesign for Sustainable Products Regulation. It requires certain products to carry a data carrier — in practice a QR code — linking to structured information about the product's composition, durability, repairability, and environmental characteristics.
Anyone quoting you a single hard DPP deadline for all products is oversimplifying. The dates arrive per category, through separate legal instruments, each with its own transition.
Independent of the data itself, the rules are strict about the plumbing: a persistent unique identifier, a physical data carrier, open and interoperable standards, long-term data availability, backup provisions, and explicit protection against vendor lock-in.
The regulation does not mandate GS1. It mandates open standards and interoperability. GS1 Digital Link is a strong candidate because it already satisfies the persistent-identifier and open-standard requirements and is supported across retail — but it is a choice, not a legal requirement, and any vendor telling you otherwise is selling.
