GS1 Digital Link

Also called: Digital Link, GS1 Digital Link URI

Definition

GS1 Digital Link is a GS1 standard for writing product identifiers such as the GTIN as a web address. Encoded in a QR code, one symbol can serve both a checkout scanner and a phone.

What a GS1 Digital Link looks like

A GS1 Digital Link is an ordinary https web address with GS1 identifiers arranged in its path. The numbers in the path are GS1 Application Identifiers followed by their values, so a scanner that understands the standard can pull out the GTIN, batch or serial number without asking a server.

For example, https://id.gs1.org/01/09506000134352/10/ABC123 means GTIN 09506000134352, batch ABC123. A brand can also use its own domain, such as https://example.com/01/09506000134352, as long as the path follows the standard.

  • /01/ followed by the GTIN (the primary key)
  • /10/ batch or lot, /21/ serial number (qualifiers in the path)
  • Other attributes, such as ?17=271231 for an expiry date, in the query string

One code for checkout and consumers

The main benefit is that one QR code can do two jobs. A point-of-sale scanner reads the GTIN from the address and rings up the item, while a shopper’s phone opens the address as a web page with product details, instructions or recycling information.

A resolver behind the domain can send different requests to different destinations, for example product information, a recall notice or a manual, based on the link type requested. This is why GS1 Digital Link is central to GS1 Sunrise 2027 and to many Digital Product Passport plans.

Frequently asked questions

Can a regular phone camera read a GS1 Digital Link QR code?

Yes. It is a normal web address inside a normal QR code, so any phone that scans QR codes can open it.

Do I need to use id.gs1.org in the link?

No. The standard allows your own domain, as long as the path follows GS1 Digital Link syntax. id.gs1.org is GS1’s own resolver.

Will a GS1 Digital Link QR code scan at the checkout?

Only on scanners that support 2D codes and GS1 Digital Link. Retail scanner upgrades are under way, which is the goal of GS1 Sunrise 2027.
