CheckBarcode

CheckBarcode is a web-based utility that provides GTIN and barcode validation for EAN-8, UPC-E, UPC-A, EAN-13, and GTIN-14 formats. The platform allows B2B users to verify barcode structural integrity using GS1 check-digit algorithms and perform GS1 prefix lookups to identify issuing jurisdictions. It operates as a static-first tool with no server-side data retention, serving catalog management, operations, and engineering teams.
