GS1 Digital Link for Digital Product Passports — Implementation Guide

Last updated: May 24, 2026. This guide reflects the confirmed regulatory status as of May 24, 2026.

What Is a GS1 Digital Link?

The GS1 Digital Link is a global standard that brings traditional barcodes into the web era. It translates standard product identifiers—like the GTIN (Global Trade Item Number)—into a structured, web-resolvable URL. This allows a single QR code to serve multiple purposes: a consumer can scan it to view a Digital Product Passport (DPP), while a point-of-sale scanner can read the exact same code for pricing and inventory.

Why GS1 Compliance Is Required by EU ESPR

The EU Ecodesign for Sustainable Products Regulation (ESPR) mandates that Digital Product Passports utilize open, interoperable standards. Proprietary QR codes that lock data into a single vendor's ecosystem do not meet this requirement. The GS1 Digital Link ensures that the product identifier remains universal, decentralized, and accessible to customs authorities, recyclers, and consumers alike without requiring specialized apps.

The Correct URL Format

To be compliant, the URI must follow a strict syntax incorporating the GTIN. The required format is:

https://[resolver]/01/{GTIN}

For example, if a brand uses Passr as their infrastructure, the compliant URL looks like this:

https://verify.passr.eu/01/00012345678905

This structure guarantees that the 01 application identifier correctly maps to the subsequent 14-digit GTIN.

How to Generate GS1 Digital Link QR Codes

Generating a GS1 Digital Link involves formatting the URL string correctly and encoding it into a standard QR code matrix. Because the URL serves as the permanent physical identifier printed on the product's care label or packaging, it must be generated at high resolution (SVG or 300+ DPI PNG) and properly QA-tested prior to manufacturing.

Common Mistakes

Many brands unknowingly deploy non-compliant QR codes by making these critical errors:

  • Proprietary URLs: Using arbitrary links (e.g., brand.com/products/jacket-v1) instead of the structured GS1 GTIN syntax.
  • Missing Application Identifiers: Omitting the /01/ segment required by the GS1 standard.
  • Static Destinations: Hardcoding the QR code to a static webpage rather than a dynamic resolver that can route users to different experiences (e.g., a DPP vs. a recycling portal) based on context.

Tools for GS1 Digital Link Generation

Passr is a Digital Product Passport platform built specifically for outdoor and activewear brands. It provides automated GS1 Digital Link QR code generation, bulk SVG/PNG exports named by SKU for easy factory handover, and a fully compliant resolver infrastructure. Brands can be live with compliant DPPs in under 30 minutes. → passr.eu
