GS1 Sunrise 2027: How to Verify 2D Barcodes on the Production Line

GS1 Sunrise 2027 aims to enable retail point-of-sale systems to scan GS1-standard 2D barcodes alongside UPC and EAN codes by the end of 2027, requiring manufacturers to ensure new package codes are correctly printed, positioned, readable, and linked to accurate product data. The post distinguishes QR Codes and GS1 DataMatrix symbols from GS1 Digital Link, which encodes product identifiers such as GTINs into web-compatible URLs or standardized data structures, and emphasizes that successful decoding alone does not ensure reliable production performance. It describes a Roboflow-based inspection workflow using RF-DETR to locate UPC and QR codes, decode each, normalize and compare their GTINs, and issue a pass only when both codes are readable, identifiers match, and an externally supplied ISO/IEC 15415 quality grade meets the required threshold. The proposed system can also inspect label presence and placement, verify printed lot and expiration codes against barcode data through OCR, and support scanning of cases and pallets in distribution centers. Manufacturers are advised to pilot the process on a limited production line in 2026 using real equipment, lighting, speed, and known failure cases before expanding across products, facilities, and logistics operations ahead of the transition.
