GS1 2D barcodes: Prepare for the next generation of product coding
GS1 2D barcodes are set to transform product identification for UK brands. Moving beyond traditional 1D barcodes, they can hold far more data in a single code — including batch and expiry information, allergens, traceability data, recycling guidance and brand messaging.
As retailers and regulators move towards smarter, more connected packaging, GS1 2D barcodes can help brands improve traceability, support compliance and create better consumer experiences.
Linx is an official GS1 UK partner, with a range of GS1-approved technologies designed to help manufacturers implement reliable, high-quality 2D codes across production environments.
What are GS1 2D barcodes?
There are two main GS1 2D barcode formats:
GS1 DataMatrix
A compact square or rectangular code with high data density, ideal for smaller products and packaging formats, particularly in sectors such as healthcare, electronics and automotive.
GS1 Digital Link QR code
A QR code that connects products to brand-controlled digital content, such as ingredient information, promotions, recycling instructions, authentication details and other consumer-facing information.
Why are GS1 2D barcodes important?
Greater consumer transparency
Enable consumers to access product information such as allergens, provenance and sustainability messaging with a simple scan.
Improved traceability and recall management
Support more precise product tracking by encoding data such as batch numbers and expiry dates, helping brands and retailers manage recalls and stock more effectively.
Stronger regulatory readiness
Help businesses prepare for evolving packaging, traceability and digital product information requirements in the UK and across international markets.
More flexible consumer engagement
Allow brands to update linked digital content without changing the printed code, making it easier to refresh campaigns, product details and recycling information over time.
