Check GTIN, EAN, UPC, SSCC, GLN and GS1 Application Identifier data locally, with no account, server or cloud. GTIN SSCC Barcode Preflight helps logistics, retail, warehouse, ERP and marketplace teams catch formal barcode-data errors before product upload, WMS entry, label print, EDI preparation or shipment processing. Paste barcode text, read the clipboard, check selected text, scan the visible page, or open a larger workbench. The extension reviews GTIN/EAN/UPC codes, SSCC-18 shipment container codes, GLN-13 location numbers and common GS1 Application Identifier element strings. Local checks include: - GTIN-8, GTIN-12/UPC, GTIN-13/EAN and GTIN-14 check digits - SSCC-18 check digits - GLN-13 check digits - GS1 AI 00 SSCC - GS1 AI 01/02 GTIN - GS1 AI 11/13/15/17 YYMMDD dates - GS1 AI 310n/320n net weight decoding - GS1 AI 10 batch/lot and AI 21 serial detection - all-zero identifier rejection - duplicate valid code warnings Everything runs locally in your browser. There is no GS1 registry lookup, marketplace lookup, product catalog lookup, label-print integration, server, login, analytics or remote code. Important: this is a formal local preflight. It does not confirm product ownership, GS1 prefix ownership, product existence, marketplace acceptance, label print quality, barcode scan quality, regulatory compliance or legal compliance.
