GS1's Sunrise 2027 initiative sets a hard deadline: by the end of 2027, retail point-of-sale systems across participating markets are expected to read GS1-compliant 2D barcodes, according to Forbes. The move replaces the UPC-A and EAN linear barcode formats that have powered retail scanning since the 1970s. The new standard allows brands to encode far more data in the same footprint—batch numbers, expiration dates, serial numbers, and URLs—while maintaining backward compatibility during the transition.

The mechanism is straightforward. Legacy one-dimensional barcodes hold **12-14 digits**. GS1 DataMatrix and QR codes carry **hundreds of characters** in the same square centimeter, readable by the same camera-based scanners retailers are already installing for self-checkout and mobile apps. Participating retailers—Walmart, Target, Tesco, and Carrefour among them—are upgrading POS firmware to parse the expanded data schema. Brands print the new codes alongside legacy UPCs during the transition window, then drop the old format once scanner penetration crosses the threshold.

Why it works: the expanded payload solves problems linear barcodes could not touch. A cosmetics brand can encode a manufacturing date and let the POS reject expired stock at scan. A supplement company can serialize every bottle and verify authenticity against a registry when a consumer scans the code with their phone. A prepared-food producer can embed a traceability link that shows the grocer—and the customer—exactly which facility packed the item and when. All without changing the physical package footprint or adding a second label.

The broader win is operational. Retailers gain lot-level recall precision: pull **batch 4472** from the shelf, leave the rest. Brands gain first-party customer access: the same QR code that rings up at Target also delivers a loyalty signup or recipe page when scanned at home. The code becomes the bridge between the shelf and the brand's owned channel, with no intermediary.

The steal for a small physical-product brand runs in three steps. First, register your Global Trade Item Numbers with a GS1 member organization if you have not already—cost is typically **under $300 annually** for a small catalog. Second, generate GS1 DataMatrix or QR codes using a compliant encoder; free tools include GS1's own barcode generator and open-source libraries like ZXing. Encode your GTIN, batch number, and a short URL pointing to a product page or verification endpoint. Third, update your packaging artwork to include both the legacy UPC and the new 2D code through **Q4 2027**, then retire the UPC in your next print run.

Execution detail: position the 2D code near the existing barcode or replace it outright if your retailer confirms scanner readiness. Test the code with a smartphone QR reader before approving the proof—if your phone cannot parse it, neither will the scanner. For serialization, connect the code to a simple database or spreadsheet that logs each code's print date and batch; even a Google Sheet behind a short URL works for a **sub-1,000-unit run**. The marginal cost is zero if you are already reprinting labels; the upside is a direct line to the customer and a recall process that does not require pulling every unit.

The next move: test your 2D barcode at a participating retailer's self-checkout **before November 2027**. If the scanner reads it and the item rings up, your package is compliant. If not, you have twelve months to fix the artwork and avoid being the brand that cannot check out when the deadline hits.

## The takeaway

Encode batch, date, and URL into a GS1 2D barcode by end of 2027; backward-compatible now, mandatory at checkout then.
