What is GS1 Digital Link and how to use it

Most brands selling into retail know a barcode change is coming. Far fewer know what GS1 Digital Link actually is, what it does at the checkout versus what it does on the web, and where to even begin setting one up. The confusion is understandable. The phrase gets used to mean a barcode, a web address, and a whole data system, often in the same sentence. That muddle is exactly why packaging teams stall.

This article fixes that. By the end you will know what GS1 Digital Link is in plain terms, who it applies to, how the URI works at point of sale, what a resolver adds on top, and the practical steps to put one on your packaging before the end of 2027. You will also see how one Australian wine brand used it to solve a real export rejection. No jargon, no hand-waving, and a clear separation between what the barcode does on its own and what the wider system unlocks once it is connected.

What is GS1 Digital Link?

GS1 Digital Link is a web-friendly way of writing a product identifier so a single QR code can carry both the GTIN a checkout needs and a web address a phone can open. It turns the barcode into a structured URL. One code holds the product ID, and optionally the batch, expiry, and serial, in a format both a till and a browser understand.

Think of it as one carrier doing two jobs. The 1D barcode that has run retail for fifty years holds a GTIN and nothing else. GS1 Digital Link keeps that GTIN but writes it inside a URL structure, so the same square of ink can identify the product at a till and open a web page on a phone. For a fuller breakdown of the syntax and link types, see our overview of the GS1 Digital Link standard and our explainer on how 1D and 2D barcodes differ.

The identifier sits in a defined path, usually in the form id.yourdomain.com/01/[GTIN]. The 01 is the GS1 application identifier for a GTIN. Add more application identifiers and the same code can carry a batch or lot number, an expiry date, and a serial number. This is what lets a wine producer, a baby food maker, or a honey exporter encode compliance-grade detail without printing a second code. If you need serial-level detail, our guide to serialised QR codes covers when and why brands add a unique serial.

How does a GS1 Digital Link work at the checkout?

A point-of-sale scanner reads the GTIN directly from the GS1 Digital Link URI structure without ever opening the web address. Checkout works offline. No internet connection, no resolver, and no external lookup are involved. The GS1 standard states that identifiers can be extracted from the code with no need for an online connection.

This is the single most misunderstood part of the whole transition, so it is worth being exact. The till does not visit a website. It parses the GTIN out of the URL the same way it would read a plain number, then it prices the item and moves on. Everything a checkout needs is in the structure of the code itself.

That matters for two reasons. First, it means a properly built GS1 Digital Link QR code satisfies point-of-sale requirements on its own, with no dependency on your servers being up. Second, it separates checkout from everything that happens when a shopper, a regulator, or an AI agent opens that same web address on a connected device. The resolver, which we cover next, handles that second layer. It plays no part in pricing your product at the till.

‍

What is a resolver and why does it matter?

A resolver is the web service that decides what a scan returns once the URL is opened on a connected device. It is not involved in checkout. It handles everything beyond the till, including consumer content, traceability data, compliance responses, AI agent queries, and routing by audience, geography, or batch.

The distinction is simple once you hold it clearly. The URI structure handles point of sale. The resolver handles the web layer. A GS1 Digital Link QR code with a valid URI is enough for basic GS1 Sunrise 2027 checkout compliance. You only need a resolver the moment you want the code to do anything past pricing, which for most brands is the entire reason to switch in the first place.

This is where context-aware routing lives. The same physical code can return EU wine labelling content when scanned in Stockholm and a marketing experience when scanned in Sydney. It can serve a regulator a compliance response and a shopper a recipe. Our piece on GS1 Digital Link link types explains how a single code maps to different destinations.

Our co-founder James Williamson is direct about timing here. His position is that the resolver is coming, not fully arrived. As he puts it, structured data using GS1 link types with the GS1 resolver is not fully in play yet, and as brands adopt 2D barcodes and the resolver system, this is what will start to pay even bigger dividends for accessing authoritative product data.

Who does the GS1 Sunrise 2027 transition apply to?

GS1 Sunrise 2027 applies to retailers and brand manufacturers across all consumer goods categories worldwide. It is an industry-led initiative, not a government mandate. Retailers will require 2D barcodes on-pack to support smarter scanning and traceability, and point-of-sale systems globally are being updated to read 2D codes by the end of 2027.

Because it is industry-led, enforcement comes from buyers rather than regulators. That changes how the deadline behaves. A retailer can decide it wants every ranged product carrying a scannable 2D code well before any formal date, and a brand that cannot supply one risks delays, rejected shipments, or lost shelf space.

The momentum is already measurable. GS1 is supporting pilots in 48 countries, covering 88 per cent of global GDP, with major brands and retailers including Walmart, Amazon, PepsiCo and L'Oréal already using QR codes powered by GS1. In the UK, GS1 UK research found that 11 per cent of its roughly 60,000 members had already implemented the technology, with a further 33 per cent planning to within 12 months. That means nearly half of its member base could be using QR codes powered by GS1 as early as 2026.

How do brands prepare, and what does it look like in practice?

Preparation is more straightforward than most teams fear, and it does not require a packaging redesign. The core steps are to generate a GS1-compliant 2D barcode, host it on your own domain in the id.yourdomain.com/[GTIN] structure, attach your GTIN, and send it to your printer. A single permanent code can then carry checkout data, compliance disclosures, and consumer content at once.

The redesign fear is the biggest blocker, and it is misplaced. You are swapping one code for a smarter one, not reworking your artwork. James makes the design case plainly. Many brands currently carry more than one code on a pack, often a retail barcode alongside a marketing QR or a batch code, and each one takes up space. Consolidating onto a single 2D barcode gives that space back to the people designing the packaging.

Small Things Wine, founded by winemaker Ian Batt, is a clear worked example. A Swedish customer rejected one of their labels because the QR code led to a single global page with marketing content that did not meet that market's rules. Adopting GS1 2D barcodes let one code serve different, compliant content per market. For food and drink specifically, our guide to QR codes on food packaging walks through the on-pack practicalities.

How does Orijin Plus help with GS1 Digital Link?

Orijin Plus is a GS1 Alliance Partner that handles GS1 Digital Link end to end. The platform generates GS1-compliant QR codes with Digital Link URIs on every plan tier, manages the resolver, and connects each scan to dynamic brand, compliance, and consumer content. The URI satisfies checkout. The managed resolver adds the contextual routing brands actually want.

The split matters in how the product is built. Every Orijin Plus QR code encodes the GTIN in a valid Digital Link URI, so it is ready for point of sale on its own. The managed resolver is what serves different content to different audiences from the same code, by market, batch, or scan context. That is how a single code can answer a regulator, a shopper, and increasingly an AI shopping agent looking for authoritative product data. You can see the wider transition framing on our GS1 Sunrise 2027 solution page, and explore dynamic routing in our explainer on dynamic QR codes. Brands looking further ahead at structured product data should also read what a Digital Product Passport is.

FAQ

Is GS1 Digital Link the same as a QR code?

No. A QR code is the physical symbol that gets scanned. GS1 Digital Link is the way the data inside it is written, as a structured web address that carries the GTIN. A GS1 Digital Link is usually encoded as a QR code, but the term refers to the URL format and identifier syntax, not the square pattern itself.

Do I need a resolver to comply with GS1 Sunrise 2027 at checkout?

No. A point-of-sale scanner reads the GTIN straight from the GS1 Digital Link URI without opening the web address, so checkout works offline with no resolver involved. You only need a resolver when you want the code to serve consumer content, compliance responses, or market-specific routing once it is scanned on a connected device.

Does switching to a GS1 Digital Link mean redesigning my packaging?

No. You replace your existing barcode with a GS1 Digital Link 2D barcode over time, not overnight. During the changeover many packs carry the original 1D barcode and the new 2D code together, so tills that cannot yet read 2D still work, and you retire the 1D barcode once retailers' point-of-sale systems read 2D codes. No full artwork redesign is needed. Longer term the switch can even free up space, because one 2D code can replace the separate marketing, authentication, and batch codes a pack often carries.

What is a GTIN and where does it sit in the link?

A GTIN is the Global Trade Item Number that uniquely identifies your product, the same number behind a traditional barcode. In a GS1 Digital Link it sits after the application identifier 01, in the form id.yourdomain.com/01/[GTIN]. Additional identifiers can be added for batch, expiry, and serial number.

When do I actually need to be ready?

The global target is for all point-of-sale systems to scan QR codes powered by GS1 by the end of 2027. In practice, individual retailers set their own timelines and can require a scannable 2D code before then as a condition of supply, so readiness is driven by your buyers rather than a single fixed date.

Can one GS1 Digital Link serve different content in different countries?

Yes, through a resolver. The barcode itself is fixed, but the resolver can route a scan to different destinations based on where it happens. The same code can return regulated wine labelling content in the EU and a marketing experience elsewhere, which is how exporters meet multiple markets' rules with one code.

Does Orijin Plus generate GS1 DataMatrix barcodes?

No. Orijin Plus generates QR codes using GS1 Digital Link URI syntax. It does not produce GS1 DataMatrix symbols. The QR code encodes the GTIN in a valid Digital Link structure for checkout and connects to the managed resolver for everything beyond it.
