Sunrise 2027 is the global retail initiative transitioning point-of-sale systems from traditional 1D EAN/UPC barcodes to 2D barcodes (QR codes with GS1 Digital Link and GS1 DataMatrix). How are variable-length GS1 Application Identifiers separated? Variable-length elements (like Lot number AI 10 and Serial number AI 21) use the ASCII 29 group separator ( or FNC1) to signal the end of data when followed by another AI. How do I decode a GS1 barcode online for free? Paste the raw scanner output into the GS1 decoder on this page and submit it. The engine maps every Application Identifier to a named field, validates GTIN and SSCC Modulo-10 check digits, and returns typed JSON in under 2ms. Can I scan a GS1 DataMatrix with a phone? Yes. Any camera-based scanner app that reads GS1 DataMatrix or QR can produce the raw payload, which you then paste into the decoder. GS1-128 and DataMatrix use FNC1 (ASCII 29) to delimit variable-length AIs, while GS1 Digital Link QR encodes the same AIs as a web URI. What is the FNC1 / ASCII 29 separator? FNC1 is a non-data symbol used in GS1-128 and DataMatrix to mark the end of a variable-length Application Identifier. It is transmitted as ASCII 29 (GS, 0x1D). Without it, a parser cannot tell where a variable-length value such as AI (10) batch/lot ends and the next AI begins. ## Complementary Enterprise APIs Seamlessly orchestrate data pipelines across adjacent financial, regulatory, and supply-chain protocols: [FDA DSCSA Drug Serialization → — Parse GS1 DataMatrix barcodes with NDC conversion for FDA DSCSA pharma compliance.](/tools/pharma-dscsa/)[FDA AccessGUDID & IMDRF UDI Decoder → — Decode unique device identification barcodes for hospital asset tracking and EU MDR.](/tools/udi-decoder/)[ISO 6346 Intermodal Container Validator → — Validate BIC container prefixes and check digits on freight packaging and pallets.](/tools/container-validator/)
