Unique Product Identification in DPP 

What is Unique Product Identification (UPI) in DPP? 

Unique Product Identification (UPI) in Digital Product Passports (DPP) refers to assigning a distinct, persistent identifier to each product or product batch. 

This identifier enables: 

• Accurate tracking 

• Data linkage across lifecycle stages 

• Seamless access to product information 

 It acts as the digital identity of a product 

Why is Unique Product Identification important in DPP? 

UPI is critical because DPP requires: 

• Product-level traceability 

• Lifecycle transparency 

• Compliance verification 

Without UPI: 

• Data cannot be reliably linked 

• Traceability breaks 

• Compliance becomes difficult 

How does UPI work in Digital Product Passports? 

UPI works by: 

1. Assigning a unique ID to a product 

2. Linking this ID to all relevant data 

3. Storing and updating data across lifecycle stages 

4. Enabling access via QR codes or digital interfaces 

This creates a connected data ecosystem 

What types of identifiers are used in DPP? 

Common identifiers include: 

• Serial numbers 

• QR codes 

• Barcodes 

• RFID tags 

• Digital IDs 

These allow both physical and digital tracking 

What is the difference between product ID and batch ID? 

 DPP may require: 

• Item-level IDs (for high-value goods) 

• Batch-level IDs (for bulk products) 

Why does ESPR require unique product identification? 

ESPR requires UPI to: 

• Enable product lifecycle tracking 

• Support circular economy goals 

• Improve transparency 

• Ensure regulatory compliance 

 It ensures every product can be individually tracked and verified 

What data is linked to a unique product ID? 

UPI connects to: 

• Material composition 

• Manufacturing details 

• Supplier data 

• Environmental impact 

• Repair and recycling data 

 It becomes a central data reference point 

How does UPI support traceability? 

UPI enables: 

• Tracking product origin 

• Monitoring movement across supply chain 

• Linking product to suppliers 

 It ensures end-to-end traceability 

How does UPI improve compliance? 

UPI helps: 

• Validate product claims 

• Provide audit-ready data 

• Ensure regulatory reporting 

 It supports: 

• ESPR 

• ESG reporting 

• Sustainability standards 

How is UPI different from traditional barcoding? 

 UPI is more advanced and integrated 

How is UPI implemented in supply chains? 

Implementation involves: 

1. Assigning IDs at production 

2. Linking IDs to product data 

3. Integrating with digital systems 

4. Enabling access via QR or platforms 

What role does QR code play in UPI? 

QR codes: 

• Store or link to product ID 

• Provide easy access to DPP data 

• Enable scanning by stakeholders 

They are the interface for accessing product data 

What is item-level vs batch-level identification? 

• Item-level: Each product has unique ID 

• Batch-level: One ID for multiple products 

Choice depends on: 

• Product type 

• Compliance requirements 

What challenges exist in implementing UPI? 

• Data standardization 

• Integration with legacy systems 

• Cost of implementation 

• Supplier alignment 

How does UPI support the circular economy? 

UPI enables: 

• Repair tracking 

• Recycling data 

• Product lifecycle visibility 

It supports sustainability goals 

What is interoperability in UPI systems? 

Interoperability means: 

Systems can share and interpret data seamlessly 

This is essential for: 

• Multi-stakeholder supply chains 

• Regulatory compliance 

How is data secured in UPI systems? 

Through: 

• Encryption 

• Access controls 

• Secure platforms 

Ensures: 

• Data integrity 

• Privacy 

What happens without UPI in DPP? 

Without UPI: 

• Data becomes fragmented 

• Traceability breaks 

• Compliance risks increase
