GS1-128 / GS1 DataMatrix Application Identifier Builder
Build GS1-128 (or GS1 DataMatrix) data strings interactively. Add Application Identifiers — (01) GTIN, (10) lot, (17) expiry, (21) serial, (00) SSCC — and get a validated, FNC1-separated encoding ready for DSCSA, FDA UDI, EU FMD, and Walmart shipping labels.
Working on DSCSA, FDA UDI, or EU FMD compliance? Read the DSCSA 2026 compliance checklist or the EPCIS supply-chain visibility primer. Render the encoded string as GS1-128 (Code 128) or GS1 DataMatrix.
