1D Barcode or 2D Code? Focus on current developments.

What to consider when labelling one-way beverage packaging

Packaging labelling may be on the verge of change: A GS1 Germany initiative aims to allow manufacturers to use 2D codes (such as QR or Data Matrix) as an alternative to the traditional 1D barcode.

While this should offer new digital opportunities – such as more data in less space – it also raises important questions for deposit-bearing one-way beverage packaging and their return within the DPG system.

What would an implemantation of 2D codes mean for return processes and system reliability?

DPG operates a highly standardised return system with over 40,000 reverse vending machines that are currently designed to read traditional 1D barcodes. Introducing 2D codes can only succeed if technology, processes, and reliability remain closely aligned.

Why start thinking about it now?

Such a transition cannot happen overnight. It requires technical adaptations, clear specifications, sufficient lead time, and – above all – early coordination among all stakeholders.

DPG Whitepaper – A basis for dialogue and decision-making

To provide a fact-based foundation and enable constructive dialogue, DPG has developed a whitepaper outlining the main technical, organisational and systemic questions concerning the potential use of 2D codes within the DPG system.

The whitepaper addresses important questions:

• What technical requirements apply to reverse vending infrastructure?
• What risks are associated with the parallel use of 1D barcodes and 2D codes?
• What impact does the introduction have on printing processes and security labeling?
• What standards and transition frameworks would be required?

DPG key takeaways – realistic and forward-looking

• A full-scale rollout of 2D codes before mid-2030 would require significant technical preparation – strategic planning is therefore essential.
• Transition phases involving both barcodes and 2D codes will bring technical challenges, particularly regarding readability – but can be managed with clear standards and coordinated processes.
• Premature use of GTIN-based 2D codes (outside the DPG context) may cause reading conflicts in the future. This should be considered early, to avoid compatibility issues in future integration.
• DPG sees early coordination between industry, retail, technology providers and system partners as key to leveraging opportunities while maintaining the reliability and acceptance of the deposit system.
