GS1 Digital Link

Connect your customers and trading partners to the product information they want and need. Our digital link factsheet has everything you need to know about using GS1 Digital Link barcode.

What is GS1 Digital Link?

GS1 Digital Link turns your product barcode into a powerful communication channel that customers can scan and be directed to a wealth of digital information about your brand and product.

It works by providing a simple, standards-based structure for the encoded data in a barcode, which connects consumers and patients to online information about the product.

Information from the digital link code can include use-by dates, nutritional information, medical product data, troubleshooting instructions, social media links, and more.

  • Digital Link web-enables barcodes
  • Can be used no matter what data carrier is used, even if it doesn’t include a URL
  • Can be used for B2B and B2C information
  • Works with a single scan of a barcode or tag
  • Uses global standards


  • No need for additional barcodes to connect consumers to more product information
  • Simplifies product packaging
  • Enhances the shopping experience
  • Strengthens consumer loyalty to brands and retailers
  • Improves supply chain efficiencies
  • Enhances traceability and speeds up recalls through the identification of specific product batches

Breaking it down - GS1 Digital Link

  1. A single, globally-recognised code that can be used by consumers, POS and the supply chain.
  2. Encoded within the barcode is a unique resource identifier (URI), which acts like a URL and other possible data fields including a GTIN, batch numbers, use-by date, etc.
  3. “Resolver” functionality acts like a look-up tool to provide information directly or redirect requests to related resources. This means information does not all need to be held in one place.
  4. Links to specific product information, e.g. instruction manuals, after-care information, traceability information, warranty, safety instructions, nutritional information, user forums, and more
  5. Works with all kinds of 1D and 2D barcodes, RFID tags, NFC and other technologies

Common scenario examples

  • Enhancing the consumer experience
  • Providing Healthcare information
  • Supply chain efficiencies
Enhancing the consumer experience

A consumer wants detailed nutritional information and additional recipes for the product. They use their smartphone to scan the QR code on the packaging that contains a GS1 Digital Link Uniform Resource Identifier (URI). This points them to a brand web page filled with recipes, nutritional information and more content. The consumer can also use a retailer app to scan the same barcode and be connected to different experiences, like ordering products, collecting loyalty points, price matching, and sharing on social media.

Providing Healthcare information

The consumer uses an app to read the pharmaceutical product’s GTIN, which is encoded in the GS1 DataMatrix barcode. Because the app knows the GS1 Digital Link standard, it uses the data in the barcode to connect to an industry-agreed “resolver” service to find the source of an electronic patient information leaflet and redirects the consumer to the leaflet in their preferred language.

Supply chain efficiencies

GS1 Digital Link can help trading partners access important safety information hazardous substances and medical products, as well as advice on safe handling, transportation and disposal of the product. Photographic evidence of supply chain events can be captured, proving that the right items were packed in the right quantity at a specific time and location.

  • When using QR codes, ensure they are encoded with a GS1 Digital Link-formatted URI.
  • Leverage your existing apps to read and use GS1 Digital Link-enabled barcodes.
  • Use resolver capabilities to connect your product identifiers to your data, wherever it is stored.
  • Only one barcode required
