GS1 syntax utilities
GS1 Digital Link & data tools
Move from a validated trade-item identifier to structured GS1 data, a web-resolvable URI and a dependable QR payload. Complex syntax is processed with the official GS1 Barcode Syntax Engine.

Build links that preserve the right distinctions
A GS1 Digital Link URI carries GS1 identifiers and data in a web address. A syntactically valid URI is not, by itself, proof that its hostname operates a conformant resolver or that the identifier belongs to a particular organization.
These tools validate encoded data locally and clearly separate syntax results from ownership, web destination, resolver and barcode print-quality questions.
