1D vs 2D Barcodes: A Quick Comparison Table for Easy Understanding

1D-vs-2D-Flyer-lowres

For decades, the one-dimensional (1D) barcode has been essential for price lookups, but it’s no longer enough to meet today’s demands for transparency, traceability, and authentication. That’s why the global supply chain is shifting toward two-dimensional (2D) barcodes, which can hold significantly more information such as best-before dates/batch number, weblinks, price and more.

With the “Sunrise 2027” initiative, the industry aims to make GS1 2D barcodes scannable at retail point-of-sale (POS) by 2027. By then, retailers will need to ensure their POS systems can scan both 1D and 2D barcodes. This shift is already in progress, with support from major retailers and brand owners across 48 countries, representing 88% of the world’s GDP.
