2D Migration

Paving the way for a global migration to 2D barcodes

2D barcodes connect business people and consumers to the information they need for inventory management, traceability programmes, sustainability initiatives and other engagement actions that will dramatically enhance the experiences for all.

Enable consumers to connect with your products and brand

As technology has evolved, so have consumer expectations. Some 2D barcodes allow consumers to use their smartphones to connect directly to the brand to enhance consumer engagement.


GS1 is partnering with industry leaders to harness the power of 2D barcodes to not only meet but exceed the increasing demands beyond the “beep” at the checkout.

With limitless, brand-authorized content at their fingertips, consumers have access to real-time information like product recalls, allergens information, promotions, reviews and instructions.

First-generation barcodes, currently used for over 1 billion products, contain a unique product identifier (GTIN). Thanks to GS1 standards, a simple scan connects each of these products to digital information that flows seamlessly across the supply chain. Now, 50 years after the first barcode was introduced, GS1 is launching two-dimensional (2D) barcodes capable of carrying additional data that can be shared beyond the “beep” at the checkout.

These new 2D barcodes are being used in manufacturing, warehousing, logistics and healthcare. They connect businesspeople to the information they need for inventory management, traceability programmer, sustainability initiatives, consumer engagement actions and more.

Brand owners can tap even more fully into their power and flexibility by encoding them with a GS1 Digital Link: in the same way a URL points to a website, a GS1 Digital Link enables connections to all types of business-to-business and business-to-consumer information.

GS1 is supporting industry with an ambition to read 2D barcodes at retail points of sale around the world by the end of 2027.

Because 2D barcodes enhance the experiences and capabilities of people up and down the supply chain, GS1 is working with industry to support the ambition to have all retailers able to read 2D barcodes at their points of sale by the end of 2027. One-dimensional barcodes will not completely go away: we expect 1D, QR and Data Matrix codes to coexist in the retail landscape.

During the last year, our teams have made tremendous progress in launching a framework to manage and support this global migration to 2D. An industry-led Mission-Specific Work Group successfully developed a future-state agreement that maps out how 2D barcodes could be used, and then group members prepared the necessary changes to the GS1 General Specifications.

We are testing scanner capabilities in a lab environment and collaborating with solution providers on algorithms and logic to read items with multiple barcodes at optimum performance scan rates. We are also continually adding to our library of resources and tools to support industry on this journey.


Two-dimensional (2D) barcodes look like squares or rectangles that contain many small, individual dots.

A single 2D barcode can hold a significant amount of information and may remain legible even when printed at a small size or etched onto a product. 2D barcodes are used in a wide range of industries, from manufacturing and warehousing to logistics and healthcare.
