GS1 Digital Link: The Identification Standard Behind the DPP
The EU points to GS1 Digital Link as the de-facto identifier standard for the Digital Product Passport. Here is how it works, why one QR can do everything, and how Izvera uses it.

At the bottom of the DPP technology stack sits a simple but essential problem: how do you uniquely identify a product in a way that any system — a phone, a customs scanner, a recycling kiosk — can resolve? The EU Commission has converged on GS1 Digital Link as the answer.
What is GS1 Digital Link?
GS1 Digital Link makes the classic GTIN (Global Trade Item Number) machine- and human-readable through a single HTTP URL. Example:
https://id.izvera.com/01/09506000134352/21/SN123
01/09506000134352→ GTIN21/SN123→ serial number
A single QR can both take a consumer to a web page and give systems a structured product identity.
Why it matters for DPP
- One QR, many destinations — the same QR can route to a consumer page, auditor data and recycler info.
- Interoperability — GS1 is global, sector- and country-agnostic.
- Backwards compatibility — coexists with existing barcode infrastructure.
Izvera's approach
Izvera uses GS1 Digital Link as the default identifier layer for every DPP. We integrate with GS1 Turkey prefixes for Turkish manufacturers and manage the URL scheme end-to-end — from product label to API call.

Bottom line
A QR is just paint without the standard behind it. GS1 Digital Link is what turns that paint into a regulated, interoperable product identifier.
