GS1 Digital Link
A GS1 standard for encoding product identifiers in a web URL inside a QR code.
GS1 Digital Link is a standard for expressing GS1 identifiers — such as a GTIN, the number behind a retail barcode — as a structured web URL, so that one QR code can serve both retail scanning and consumer-facing content.
Shape. The identifier appears as a path, for example
https://example.com/01/09506000134352, where 01 is the GS1
application identifier for a GTIN. Batch, serial and expiry can follow in the same
structured form.
Why it exists. Retail is migrating from the one-dimensional barcode to two-dimensional codes. A Digital Link code can be read at a checkout for the product identifier and by a shopper's phone for provenance, allergens, recycling or instructions — replacing two separate marks with one.
Relevance. Mostly for packaged goods entering retail distribution. For a café menu or a yard sign it is unnecessary complexity.
In practice
A food producer replaces the barcode and a separate marketing QR code with one Digital Link
code: https://brand.example/01/09506000134352/10/BATCH42. The checkout reads
01 as the GTIN; a shopper's phone loads a page showing allergens, origin and
recycling guidance for that specific batch.
One printed mark, two audiences, and batch-level traceability that a plain barcode cannot carry. The cost is coordination — GS1 registration, a resolver, and packaging artwork changes — which is why this is a packaged-goods concern rather than a café one.
Questions
Do I need GS1 membership?
To use a GTIN you already have, no. To obtain GTINs for new products, yes — they are issued by GS1 member organisations.
Is this replacing barcodes?
Gradually. GS1 has coordinated an industry transition toward 2D codes at point of sale, but rollout depends on retailers upgrading scanners, so both will coexist for years.
