According to PKN Packaging News , the adoption of 2D barcodes in packaging is accelerating as regulators and retailers demand greater product traceability and data transparency. Unlike traditional 1D barcodes, 2D variants such as QR codes and Data Matrix codes can store significantly more information—including batch numbers, expiry dates, and serial numbers—within a single scannable symbol.
The shift is largely driven by compliance requirements in industries like food, pharmaceuticals, and healthcare, where regulations such as the FDA's Drug Supply Chain Security Act (DSCSA) and EU Falsified Medicines Directive mandate unique product identifiers. Standards bodies like GS1 are promoting the transition to 2D codes, enabling brands to embed GS1 Digital Link URLs that connect physical products to digital information, such as recall notices or recycling instructions.
For packagers and manufacturers, adopting 2D barcodes means upgrading printing and scanning infrastructure, but the long-term benefits include reduced counterfeiting, improved recall efficiency, and enhanced consumer engagement. As more countries enforce traceability mandates, 2D barcodes are expected to become a standard feature on most consumer goods packaging within the next few years.
