GS1 Sunrise 2027: A Practical Guide for Brands

By 2027, retailers around the world will start scanning QR codes at the checkout register instead of traditional 1D barcodes. This transition, called Sunrise 2027, is the largest change to the global retail supply chain in 50 years. Every consumer-packaged-goods brand, retailer, and product manufacturer needs to understand it.

GS1 — the international standards body that manages the GTIN (the number behind every UPC barcode) — has been working with retailers (Walmart, Tesco, Carrefour, Kroger) for years on this transition. The goal: replace 1D barcodes with 2D barcodes (QR codes or DataMatrix codes) that carry far more product information beyond just identification.

This guide covers what Sunrise 2027 actually requires, what kind of QR codes work for compliance, and the practical steps brands should take in 2026 to prepare.

What Is GS1 Sunrise 2027

GS1 Sunrise 2027 is the agreed-upon target date when major retailers will be able to accept 2D barcodes (specifically GS1-formatted QR codes and DataMatrix codes) for point-of-sale scanning, in addition to or instead of traditional 1D UPC barcodes.

The "sunrise" framing comes from previous standards transitions (like Sunrise 2005, when 13-digit GTINs replaced 12-digit UPCs at North American retailers). It signals the date by which retail systems will be ready to read the new format. Brands that switch sooner can start using 2D codes immediately; brands that wait can continue using traditional 1D barcodes alongside or instead.

Why the Industry Is Making This Change

• Richer product data at scan. A QR code can encode hundreds of times more data than a 1D barcode. Beyond GTIN, it can include batch number, expiration date, country of origin, and a unique serial number per product.
• Consumer engagement. Consumers can scan the same QR code with their phone and reach the brand's product page, recipe ideas, recall notices, sustainability info, and authenticated proof. One code serves both retail systems and consumers.
• Recall efficiency. When a product is recalled, the QR code can encode batch-specific data, letting retailers and consumers identify exactly which units are affected without recalling the entire product line.
• Counterfeit reduction. Unique serialized QR codes per product enable authentication — counterfeit products without valid serial numbers can be detected at the register or by consumers.
• Regulatory compliance. Increasing regulation around food traceability (FDA Food Safety Modernization Act, EU Farm-to-Fork) requires lot-level identification that 1D barcodes cannot carry.

What Is GS1 Digital Link

GS1 Digital Link is the technical standard that defines how QR codes carry GS1 data. It uses standard URL syntax with GS1 application identifiers (AIs) embedded as URL path segments.

A GS1 Digital Link QR code looks like: https://example.com/01/9780123456789/10/A1B2C3

Where 01 is the GTIN application identifier, 9780123456789 is the product GTIN, 10 is the batch number AI, and A1B2C3 is the actual batch number. Retail POS systems read the GS1 data; consumers' phones see the URL and can be redirected to a product landing page.

Timeline and Adoption

• 2025 (now). Many major retailers (Walmart, Tesco, Carrefour) accept 2D barcodes alongside 1D. Some POS systems can read both.
• 2026. Industry-wide adoption accelerating. Most major retailers globally have 2D-capable scanners. Brands begin transitioning packaging.
• 2027 (Sunrise target). Industry-wide commitment for 2D barcode acceptance at major retailers. Some retailers may begin requiring 2D for new products.
• Post-2027. Gradual phase-out of 1D-only barcodes for new products. 1D barcodes likely remain readable for years for legacy SKUs.

What This Means for Your Brand

If you sell consumer products that go through retail checkouts, you need to start planning now. Three categories of decisions:

• Packaging refresh cycles. Most brands refresh packaging every 18–36 months. Plan to incorporate GS1 Digital Link QR codes in your next refresh — earliest to launch, latest to comply.
• Data infrastructure. Decide what data to encode beyond GTIN. Batch numbers, expiration dates, and serial numbers require connecting your QR generation pipeline to your manufacturing/ERP systems.
• Consumer-facing landing pages. Decide what consumers see when they scan. The same QR code that retail systems read can show consumers a branded product page, allergen info, recall notices, or anything else.

Steps to Take in 2026

1. Inventory your SKUs. List every product you make, where it's sold, and which retailers carry it. Prioritize the highest-volume SKUs for early conversion.
2. Engage your major retail buyers. Ask each retailer what their 2D barcode requirements and timelines are. Walmart, Kroger, Costco, Target, Albertsons all have specific guidance.
3. Audit your packaging artwork process. Confirm your printers can produce QR codes at the required print quality. Most modern printers can; some legacy systems cannot.
4. Choose a QR code generation platform that supports GS1 Digital Link format. Both static (per-SKU) and dynamic (per-batch) approaches are viable.
5. Connect your manufacturing systems if you need batch-level or serialized QR codes. This is the biggest infrastructure project — give it 6–12 months.
6. Design the consumer experience. What landing page do consumers see when they scan? Generic product page? Allergen info? Recipe ideas? This is also a brand opportunity.
7. Pilot with one SKU. Launch GS1 QR codes on a single product line, monitor scan data and retailer feedback, refine before rolling out across the catalog.
8. Track timeline against retailer milestones. Some retailers will mandate 2D in 2026, others 2027, others later. Plan against the earliest mandate.

Static vs Dynamic GS1 QR Codes

For products without batch-specific data, a static GS1 QR code per SKU works fine. The QR is generated once with the GTIN and never needs updating.

For products with batch-level data (food, pharmaceuticals, cosmetics with expiration dates), each batch needs its own QR code. This requires either:

• Print-on-demand QR generation integrated with your manufacturing line — each unit gets a unique QR with its serial/batch encoded.
• Dynamic QR codes where one printed QR redirects to a database lookup based on the production batch — more flexible but requires backend infrastructure.

How QRCodeStack Helps

QRCodeStack supports GS1 Digital Link format for products that need GS1 compliance. Generate static GS1 QR codes per SKU, integrate via API for batch-level dynamic generation, or use bulk CSV import for catalog-wide rollouts.

Combined with QRCodeStack's analytics, brands can see which products are being scanned at retail, which consumer-facing landing pages convert best, and how scan patterns vary by region. This data informs both compliance and marketing strategy.
