GS1 Digital Link: The Future of Product QR Codes

GS1 Digital Link is a standard that allows product identification numbers (like GTINs) to be encoded in web URLs. This enables QR codes to serve multiple purposes: retail scanning, consumer information, and regulatory compliance.

What is GS1 Digital Link?

Traditional barcodes (UPC, EAN) contain only a product identifier. GS1 Digital Link embeds that identifier in a URL structure:

https://id.gs1.org/01/09506000134352

This URL can:

• Be scanned at retail POS systems
• Link consumers to product information
• Provide access to DPP data
• Support multiple data carriers (QR, DataMatrix)

GS1 Sunrise 2027

GS1 has announced "Sunrise 2027" - the global retail transition from 1D barcodes to 2D barcodes:

• 2027: Major retailers begin accepting 2D barcodes at checkout
• 2028+: 2D barcodes become standard for retail
• Future: 1D barcodes phased out

Why This Matters for DPP

EU Digital Product Passport regulations align with GS1 standards:

• QR codes must use GS1 Digital Link format
• Enables seamless integration with retail systems
• Supports resolver infrastructure for data access
• Ensures global interoperability

Technical Structure

A GS1 Digital Link URL contains:

• Domain (can be your own or GS1's)
• Application Identifier (01 for GTIN)
• Product identification number
• Optional: serial number, batch, expiry

Example:

https://lnk.eco/01/09506000134352/21/ABC123
