GS1 Digital Link for Brand Managers
Key Takeaways
- GS1 Digital Link converts a product's GTIN into a structured URL — one code that serves retail checkout scanners and consumer smartphones simultaneously.
- Sunrise 2027 (January 2027) is the global POS readiness deadline: any new packaging designed from late 2025 onward should carry a GS1 Digital Link 2D barcode.
- A properly structured GS1 Digital Link also serves as the technical carrier for EU Digital Product Passport data under ESPR — two compliance obligations, one code.
- Fewer than 15% of packaging teams currently understand the full commercial implications of GS1 Digital Link for brand engagement and first-party data.
Your barcode has always been a number. GS1 Digital Link makes it a web address.
That sounds like a technical footnote. It isn't. It is a structural change to how products carry information — one that collapses the distance between physical packaging and digital experience, between retail checkout and customer relationship, between product compliance and brand engagement. And it is arriving on a fixed timeline that your packaging team is already working to.
Most brand managers are hearing about GS1 Digital Link from their supply chain or compliance teams first. That is the wrong department to own it. The implications for customer experience, marketing, and product lifecycle are as significant as the operational ones. This article is the briefing brand teams should have received eighteen months ago.
| Metric | Impact |
|---|---|
| Barcode transition deadline | Sunrise 2027 (Jan 2027 POS capability required) |

| Operational cost of dual codes | Extra packaging real estate, duplicate scan validation |
| DPP carrier alignment | GS1 Digital Link is ESPR-preferred mechanism |
| Retailer readiness | Major retailers (Walmart, Carrefour, Kroger) active participants |
| Brand teams informed | <15% of packaging teams understand GS1 Digital Link implications |
Competitors: BrandedMark (GS1 native), generic QR platforms
GS1 Digital Link is not a competitive product — it's a global standard. But compliance with the standard is rare. Most QR platforms generate links that don't parse correctly in GS1 resolvers. BrandedMark is built as GS1-native from the ground up: resolver domain registered with GS1, AI encoding enforced, ESPR-compatible data schema. Generic QR generators (Bitly, QR code libraries) can generate a link that looks like GS1 Digital Link but doesn't validate structurally — and will fail retail scanning post-2027. For brand teams, choosing a GS1-compliant platform now (like BrandedMark) versus retrofitting later is the difference between Sunrise 2027 looking like a compliance project versus a crisis.
The 30-Second Version
Here is what GS1 Digital Link is, stripped of jargon.
Today, the barcode on your product (the UPC or EAN) encodes a GTIN — a Global Trade Item Number. That number tells a retail scanner how much the product costs and updates stock levels. It does exactly one job: point-of-sale identification. It has done that job since 1974.
GS1 Digital Link converts that GTIN into a URL. Instead of just encoding 0123456789012, the barcode encodes https://brandedmark.com/01/0123456789012 — a web address that conforms to the GS1 Digital Link standard. A retail scanner reads the GTIN from that URL exactly as before. But a smartphone camera reads it as a link and opens a web experience.
One code. Two audiences. No conflict.
The brand can add more data to that URL — serial number, batch or lot, expiry date, country of origin. Each piece of data follows the GS1 standard structure, which means it is machine-readable by any GS1-compliant system in any market. The same 2D barcode that clears checkout in London, tracks provenance in a retailer's warehouse in Chicago, and activates a customer warranty page on a phone in Tokyo — all from one print on your packaging.
This is the architecture. Sunrise 2027 is the deadline.
What's Changing at Retail
The Move From 1D to 2D
Linear barcodes — the familiar row of black and white stripes — encode between 8 and 14 digits. They have served global retail for over fifty years, but they are at their information capacity ceiling (GS1 Global Office, "Sunrise 2027: Moving to 2D Barcodes," 2023). A 2D barcode (QR code, DataMatrix, or similar) encodes thousands of characters in the same or smaller physical space.
GS1, the global standards body that governs product identification, has been working with major retailers — Walmart, Target, Kroger, Carrefour, and others — on a coordinated global transition from 1D to 2D barcodes at point of sale. The programme is called Sunrise 2027.
The Sunrise 2027 Deadline
From January 2027, point-of-sale scanners at participating retailers are expected to be capable of reading GS1 2D barcodes. For brand managers, the practical implication is this: any product packaging designed or refreshed from late 2025 onward should carry a 2D barcode that complies with the GS1 Digital Link standard, because retailers will begin retiring 1D-only scanning equipment from 2027.
This is not a regulatory deadline in the way that EU DPP compliance is regulatory — there is no fine for missing it. But a product that cannot be scanned at checkout is a product that cannot be sold. The operational risk of missing Sunrise 2027 is supply chain disruption, not a regulatory penalty.
For most brands, the packaging redesign cycle means decisions made today will still be on shelf in 2027. The deadline is effectively now.
What "2D Barcode" Means in Practice
Not all QR codes are GS1 Digital Link compliant. A QR code that points to https://yourbrand.com/register is a QR code. A QR code that encodes https://id.brandedmark.com/01/09506000164996/21/A123456 — where 01 is the GS1 Application Identifier for GTIN, 21 is the AI for serial number, and the domain is a registered GS1 resolver — is a GS1 Digital Link.
The distinction matters at retail. Standard QR codes return a URL. GS1 Digital Link QR codes return a structured data payload that retail scanning systems can parse for GTIN, price lookup, and inventory management. Without that structure, the barcode does not clear a GS1-compliant checkout.
What This Means for Brand Managers
One Code, Multiple Jobs
The most important commercial implication of GS1 Digital Link is that your retail barcode and your customer engagement QR code are now the same object.
Today, many brands print a linear barcode for retail and a separate, marketing QR code linking to their website or a registration page. Two codes, two jobs, two potential consumer touchpoints, two sets of placement constraints on already crowded packaging. Sunrise 2027 makes this duplication unnecessary. A single GS1 Digital Link 2D barcode handles retail scanning and resolves to a rich web experience for consumers — simultaneously, from the same print.
This has direct implications for connected packaging strategy: the QR code you place on packaging for consumer engagement is no longer a discretionary addition that might be removed in the next packaging refresh. It is the barcode. It is structurally embedded in packaging compliance.
Brand teams that treat this as a passive compliance exercise will end up with a barcode that clears checkout and opens a generic product page. Brand teams that engage now will end up with a barcode that clears checkout, opens a personalised post-purchase journey, captures warranty registration, delivers EU Digital Product Passport data, and feeds a first-party customer database — from one code.
The QR Code Is Now the Front Door
Once the GS1 Digital Link barcode is the standard product identifier, every consumer interaction that previously required a separate QR code now happens through the same code that your retail partners are scanning at checkout. That convergence changes the conversation about QR code placement.
The question is no longer "should we add a QR code?" The question is "what experience does our required barcode unlock for consumers?"
The answer can be a dynamic QR landing page that changes based on who is scanning (retail system vs. consumer phone), when they are scanning (pre-purchase in-store vs. post-purchase at home), and which specific unit they have (via serial number). A parent scanning at a pharmacy gets product safety information. A consumer scanning at home during setup gets onboarding and warranty registration. A service technician scanning during a repair gets the service manual and parts diagram. Same barcode. Different resolver destinations.
The DPP Connection
GS1 Digital Link is also the primary technical carrier for EU Digital Product Passport data under ESPR (Ecodesign for Sustainable Products Regulation). The Digital Product Passport requires that each product carry a machine-readable link to its product data (European Commission ESPR Delegated Regulation Working Document, 2024) — traceability, materials, repairability, sustainability information. GS1 Digital Link is the GS1-endorsed mechanism for carrying that link.
This means that a brand building GS1 Digital Link infrastructure for Sunrise 2027 is simultaneously building the technical foundation for Digital Product Passport compliance. These are not two separate initiatives. They are the same infrastructure serving two regulatory and commercial requirements.
10 Questions to Ask Your QR Platform
Not all QR code or product experience platforms are built for GS1 Digital Link. Before committing to a platform for your post-2026 packaging, these are the questions that separate compliant, scalable infrastructure from a QR code generator with a nice dashboard.
1. Do you support GS1 Digital Link URI syntax? The platform must generate URLs that conform to GS1 Digital Link structure — correct Application Identifier prefixes, correctly encoded GTIN and serial data, and a resolver domain registered under GS1's Digital Link resolver network. Ask to see a sample URI.
2. What is the resolver architecture? GS1 Digital Link works through a chain of resolvers: a global GS1 resolver routes to a brand-level resolver, which routes to the experience. Where is the brand-level resolver hosted? What is the SLA for uptime? A resolver that goes down takes every product's QR code with it.
3. Can you serve different content to different audiences from the same code? The same code must serve retail scanners (GTIN data) and consumers (web experience). Can the platform detect the scanning context and route accordingly? Can it serve different content based on geographic location, scan timing, or consumer-provided data?
4. Do you support item-level serialisation? A GS1 Digital Link barcode without a serial number is a product-level code. Every unit carries the same URL. Useful for basic product information; not useful for individual warranty registration, anti-counterfeiting, or lifecycle tracking. Confirm whether the platform supports unique serial numbers per unit and at what cost.
5. Is the platform DPP-compatible? Can it expose product data in the data formats required for EU Digital Product Passport — including the specific data elements ESPR will mandate for your product category? Does it support the Digital Product Passport schema standards currently being finalised by GS1 and the European Commission?
6. What is the data ownership model? Scan data is first-party customer data. Who owns it — you or the platform? Can you export the full dataset at any time? Is scan data used for the platform's own analytics or cross-brand profiling? Understand this before your packaging goes to print.
7. Can you handle our volume? If you ship 500,000 units per year across 50 SKUs, each with a unique serial number, you need 500,000 unique QR codes generated and live in the resolver before shipping. What are the generation and resolver query limits? What is the latency at peak scan volumes?
8. How do you handle content versioning? Product information changes: regulatory updates, safety notices, recalls, seasonal promotions. The platform must support updating the destination of a live code without changing the code itself. Confirm that content updates are versioned, auditable, and applied without service disruption.
9. What is the minimum viable setup for retail compliance? If your primary urgency is Sunrise 2027 checkout compliance, what is the minimum configuration needed to get a GS1 Digital Link barcode that passes retail scanning? Some platforms require full onboarding and subscription before generating a single compliant barcode; others offer a lighter compliance-first path.
10. What does migration look like? Switching QR platforms after packaging has been printed is not straightforward. The resolver domain is embedded in the code. Understand upfront what a platform migration entails — whether you retain your resolver domain, whether historical scan data is exportable, and what contractual lock-in looks like.
What to Ask Your Packaging Team
Brand managers who engage early with their packaging team avoid the last-minute compliance scrambles that produce poor print quality and missed deadlines. These are the practical questions to raise now.
Print quality and contrast. GS1 Digital Link QR codes must meet GS1's print quality grade requirements (minimum ISO/IEC 15415 Grade C for most applications, Grade B for serialised codes). Ask your print supplier whether they are scanning and grading finished codes, not just visually inspecting them. A code that looks clean to the eye can fail a scanner.
Minimum size. The minimum recommended size for a GS1 Digital Link QR code intended for consumer scanning is 10mm x 10mm, with a quiet zone (white border) of at least 4 modules on all sides. For retail scanning, larger is generally better. Confirm that packaging layout accommodates these minimums before finalising dielines.
Placement. Retail scanners typically scan the primary barcode face. Consumer scanning happens in-context — during unboxing, setup, or product use. These are often different surfaces of the same package. For Sunrise 2027 compliance, the 2D barcode should replace or accompany the primary 1D barcode on the retail-facing panel. For consumer engagement, placement on the product itself (not just the box) extends the code's useful life beyond the initial unboxing moment.
Serialisation workflow. If you are implementing item-level serialisation, the production line must receive unique codes per unit — either pre-printed inserts, in-line label printing, or laser engraving. This is a packaging engineering and supply chain question, not just a design question. The earlier your operations team is involved, the smoother the implementation.
Testing at launch. Before printing the full production run, test a sample of codes across multiple devices (iPhone, Android, older models), in multiple lighting conditions, and at the intended scan distances. Test retail scanner compatibility with your retail partners directly if possible. Document and retain scan test results as part of your quality assurance record.
Month-by-Month Action Timeline to 2027
Brand managers who treat Sunrise 2027 as a single deadline will miss it. It is a sequence of decisions, each with lead times. Here is a realistic timeline for a brand that has not yet started.
April–June 2026: Strategy and platform selection Audit current barcode and QR infrastructure. Identify all active SKUs and their packaging refresh cycles. Define what you want the consumer experience to do (registration, DPP, support, commerce). Select and onboard a GS1 Digital Link-compatible platform. Obtain your GS1 Company Prefix if you do not already have one.
July–September 2026: Pilot implementation Implement GS1 Digital Link on one or two SKUs — ideally products with an upcoming packaging refresh. Generate serialised codes. Test retail scanner compatibility with at least two major retail partners. Build and test the consumer experience linked to the codes. Confirm DPP data structure if applicable to your product category.
October–December 2026: Rollout planning Based on pilot results, define the rollout scope and sequence for remaining SKUs. Establish serial number generation and management workflows with your packaging suppliers. Brief retail partners on the transition from 1D to 2D barcodes. Train internal teams on the platform and reporting.
January–March 2027: Active rollout All new packaging designs carry GS1 Digital Link 2D barcodes. Existing packaging still in production continues on existing codes until the next refresh. Monitor scan data and resolver performance. Address any retail scanner compatibility issues as they arise.
Q2 2027 and beyond: Optimisation With the baseline infrastructure live, the focus shifts from compliance to experience. A/B test consumer landing page content. Build registration and engagement flows on top of the resolver infrastructure. Begin implementing DPP data requirements as category-specific ESPR regulations are finalised.
The Brands That Move First Win Twice
GS1 Digital Link is not optional for any brand with significant retail presence — Sunrise 2027 makes that clear. But the brands approaching it only as a compliance exercise will build exactly that: a compliant barcode that does nothing more than it must.
The brands that engage now — that treat the required 2D barcode as the front door to a connected product strategy — get something far more valuable. They get a permanent, standards-compliant, scalable channel to every customer who has ever bought their product. Not through a retailer's CRM. Not through an app with a 12% install rate. Through a code that is already on the product, already visible during unboxing, already trusted by retail infrastructure worldwide.
That is not a compliance outcome. That is a competitive position.
The connected packaging checklist covers the broader packaging and experience decisions that sit alongside GS1 Digital Link implementation. The Digital Product Passport overview covers what DPP compliance will require once ESPR category regulations are finalised. For a deeper look at the Sunrise 2027 timeline and retailer readiness, see our GS1 Sunrise 2027 briefing.
The standard is set. The timeline is fixed. The only question is whether your brand uses it to do the minimum — or to build something that outlasts the deadline.

FAQ
If we're already printing QR codes on packaging for marketing, can't we just repurpose those for GS1 Digital Link?
No — repurposing a generic QR code as a GS1 Digital Link requires changing the encoding structure (to conform to GS1 Application Identifier syntax) and registering your resolver domain with GS1's resolver network. Generic QR codes pointing to yourbrand.com/product will scan on consumer phones but will fail retail scanning systems expecting GS1 Digital Link structure post-2027. You cannot simply slap a GS1 resolver domain on your existing code. The structure has to be rebuilt from the encoding layer up.
We don't ship to EU markets yet — does Sunrise 2027 still apply to us?
Sunrise 2027 is global from the perspective of retail infrastructure. If you have any products scanned at US retailers using GS1-compliant POS systems, those systems are upgrading to 2D capability. That said, the obligation to print 2D is enforced by retailer requirements, not by regulation. If your retailers don't require 2D by 2027, you have more time. But if you sell into any territory with major retailers (Walmart, Carrefour equivalents), assume they will require it. Better to plan now than negotiate under deadline.
How do we avoid our GS1 Digital Link barcode becoming obsolete if we switch platforms down the line?
This is why resolver domain ownership matters. When you implement GS1 Digital Link, you should own or have contractual rights to the resolver domain — the part of the URL before the product data. If your platform is BrandedMark and we're providing the resolver, you have a contractual right to data portability and domain control. If a vendor-specific resolver domain gets baked into your codes and that vendor goes out of business or you want to switch, you're stuck. This is a due-diligence question for any GS1 Digital Link platform: who owns the resolver domain, and what happens if the vendor relationship ends?
