GS1 Digital Link expresses a product identifier such as a GTIN as a web URL, so a single QR or DataMatrix can point both point-of-sale systems and consumers to the right online resource, including a Digital Product Passport. It lets one carrier serve both identification and passport access.
How does GS1 Digital Link relate to the DPP?
A passport needs a persistent, resolvable link on the physical product. A GS1 Digital Link URI structured around the GTIN, and optionally a batch or serial, gives that link a standard, machine-readable form that resolvers and scanners understand, rather than a fragile ad-hoc URL.
Product, batch or serial level?
The identifier level should match the passport's granularity. A model-level passport can resolve from the GTIN, while item-level cases such as serialized industrial batteries resolve from the GTIN plus a serial. Confirm identifier ownership and the applicable product rules before labels go into production.
How does DPP Shield support it?
DPP Shield generates QR and DataMatrix carriers using GS1 Digital Link paths at the level you choose, and keeps the resolved passport URL stable across versions, so a printed label keeps working after the underlying data is updated and re-published.
Frequently asked questions
Do I need a GS1 company prefix?
To use a GTIN you need a GS1-issued company prefix. DPP Shield enforces verified prefix ownership before publishing GTIN-based identifiers.
Can one QR code do identification and the passport?
Yes. That is the purpose of GS1 Digital Link: one carrier resolves to the appropriate resource, including the passport.
