For decades, traditional 1D barcodes have helped retailers identify products quickly at checkout. But modern supply chains require more than simple identification. The GS1 Sunrise 2027 initiative introduces the transition from 1D barcodes to 2D codes such as GS1 DataMatrix and QR Code, enabling far richer product information to be accessed with a single scan.
Unlike traditional barcodes that only identify the product type (GTIN), 2D codes can include batch numbers, expiration dates, and even unique serial numbers. During the transition, most brands will use dual-marking, placing both 1D and 2D codes on packaging so existing retail systems continue to work while new systems begin using enhanced data.
But the real opportunity goes beyond adding more data to a barcode.
By assigning a unique serial number to every individual product, companies can create full visibility across their supply chains.
Serialization enables:
Programs such as Amazon Transparency already use serialization to verify product authenticity before items reach customers.
The shift to 2D barcodes also creates new opportunities across industries. Retailers can manage expiration dates more efficiently, while sectors like apparel are preparing for initiatives such as Digital Product Passports, giving consumers insight into product origin and sustainability.
Technologies like GS1 Digital Link make it possible for a single scan to serve multiple purposes—from logistics and retail operations to consumer engagement.
Sunrise 2027 is often viewed as a technical deadline. In reality, it is a strategic opportunity.
Companies that simply update their packaging will meet the requirement.
Companies that implement end-to-end track and trace will gain full supply chain visibility, stronger brand protection, and greater consumer trust.
In a world where supply chains are becoming increasingly transparent, this transition is not just about barcodes—it’s about building the digital foundation for the next generation of connected products.
