Barcodes have been part of packaging and production for decades, but the role they play is changing quickly.

For manufacturers, a barcode is no longer just something that allows a product to scan at a checkout. It is becoming a key part of product traceability, supply chain visibility, compliance, recall readiness and consumer transparency.

That is why GS1 standards are becoming increasingly important across industries such as food, beverage, life sciences, healthcare, retail and FMCG.

At Codico, we work with manufacturers across Ireland and Northern Ireland to help them implement reliable coding, marking and labelling systems that support GS1 compliance and prepare production lines for the future of barcode technology.

What is GS1?

GS1 is the global standards organisation behind many of the barcode and product identification systems used throughout retail, healthcare, manufacturing and supply chains.

GS1 standards help businesses identify products consistently using codes such as GTINs, GS1 DataMatrix codes, linear barcodes and GS1 QR codes.

For manufacturers, this matters because accurate product identification can support better traceability, easier recall management, stronger compliance and greater visibility across the supply chain.

Why GS1 compliance matters

Manufacturers are under growing pressure to provide accurate product information at every stage of the supply chain.

Retailers, regulators and customers all expect products to be clearly identifiable and traceable. This is especially important in sectors where batch numbers, expiry dates, serialisation or product authentication are required.

GS1-compliant coding and labelling can help support:

• Product traceability
• Batch and lot tracking
• Recall readiness
• Retail compliance
• Supply chain visibility
• Consumer transparency
• Product authentication

Getting this right depends on more than simply adding a barcode to packaging. The code must be printed clearly, positioned correctly, compatible with the packaging material and suitable for the production environment.

Preparing for the future of barcodes

One of the biggest changes manufacturers need to be aware of is the move towards next-generation 2D codes, including QR codes powered by GS1.

Through GS1’s Ambition 2027 initiative, the industry is preparing for wider use of 2D barcodes that can carry more data than traditional linear barcodes. These codes can help connect product packaging to richer information such as batch details, expiry dates, product data, supply chain information or consumer-facing content.

For manufacturers, this creates an opportunity to improve traceability and product communication. However, it also means production lines need to be ready to print high-quality, scannable codes consistently.

Common GS1 code types

There are several GS1 code types that manufacturers may need to consider, depending on their industry and application.

GTIN
A Global Trade Item Number is used to uniquely identify a product.

GS1 DataMatrix
Often used in healthcare, life sciences and regulated industries where compact codes and traceability are required.

GS1 QR codes
Next-generation codes that can store more structured product and traceability information.

Linear barcodes
Traditional barcode formats that are still widely used across retail, logistics and manufacturing.

The right solution will depend on the product, packaging material, production line, industry requirements and how the code needs to be used.

How Codico supports GS1 implementation

As a GS1 Ireland Gold Partner, Codico helps manufacturers choose and implement coding, marking and labelling systems that support GS1-ready production.

Our team can support with:

• Barcode and QR code printing systems
• Variable data and serialisation printing
• Production line integration
• Print quality considerations
• Code placement guidance
• Traceability support
• Technical consultation and aftersales support

We work with a wide range of technologies, including inkjet, laser, thermal transfer, print and apply labelling, outer case coding and automated coding solutions.

Key considerations before implementing GS1 codes

Before introducing or upgrading a barcode or QR code solution, manufacturers should consider a few important factors.

The first is print quality. Poor print quality can lead to scanning issues, rejected products or compliance problems.

The second is substrate compatibility. A solution that works on cardboard may not be suitable for foil, plastic, glass, metal or flexible packaging.

The third is production line integration. The coding system must be able to keep up with line speeds and fit into the existing production process.

Finally, manufacturers should consider verification and future requirements. As 2D codes become more widely adopted, it is important to make sure your production line is prepared for what retailers, regulators and supply chain partners may expect next.

Speak to Codico

GS1 compliance and 2D barcode adoption do not need to be overcomplicated, but they do need to be planned correctly.

Whether you are reviewing your current barcode setup, preparing for QR code adoption or looking to improve traceability across your production line, Codico can help.
