GS1's implementation guideline says retail POS systems should be able to read and process GTINs from both linear and GS1-compliant 2D barcodes by the end of 2027.
What changed
GS1's guideline covers the voluntary transition from linear codes to GS1-compliant 2D barcodes at retail POS. It notes that not every imaging scanner is automatically ready and that scanner output, the host system, code placement, data syntax, and operating processes all affect readiness.
Buyer and integrator analysis
Scanner capability alone is not enough. Retailers should validate decoding modes, host-system data handling, barcode placement, fallback behavior, and store-level rollout before claiming 2D readiness.
Project checklist
- Inventory scanner models, firmware, decode modes, and the data each device can transmit.
- Test GTIN plus attributes through POS, middleware, ERP, promotion, recall, and receipt workflows.
- Pilot linear and 2D co-location, scan speed, exception handling, and staff procedures before rollout.
