A packaging manager at a food brand told us he’d printed 200,000 units with a static QR code pointing to a product page. Two months later, the page URL changed after a website migration. Result: 200,000 packages in circulation scanning to a 404 error, with no way to fix it.
That’s exactly the kind of situation a dynamic QR code on packaging prevents. In 2026, a QR code on your packaging isn’t a novelty. It’s a direct channel between your brand and your customer, and increasingly, a regulatory requirement.
This guide covers the practical use cases, how to set it up, and the mistakes that cost brands time and money.
Why Packaging Is Adopting QR Codes in 2026
Three things are accelerating adoption this year.
GS1 Sunrise 2027. The global organisation behind barcodes is driving the transition to QR code-based GS1 Digital Links. By 2027, a single QR code on packaging will be able to replace the traditional barcode while offering additional functionality: product information, traceability, promotions. Brands that start now will be ahead when the deadline hits.
The EU Digital Product Passport (DPP). European regulation will progressively require a digital passport for certain product categories. The QR code on packaging is the natural vehicle: origin, composition, carbon footprint, recycling instructions, all accessible with a scan.
Consumer behaviour. Recent studies show over 60% of consumers regularly scan QR codes on products they buy. The question isn’t whether your customers will scan. It’s what they’ll find when they do.
7 Practical Use Cases for QR Codes on Packaging
1. Traceability and product origin
The QR code links to a page detailing the product journey: manufacturing location, production date, batch number, certifications. Particularly relevant in food and beverage, cosmetics, and pharmaceuticals, where transparency drives purchasing decisions.
2. Post-purchase consumer engagement
The product is in the customer’s hands. That’s the highest-intent moment for interaction: recipes, usage tutorials, loyalty programme sign-up, referral offers. The QR code turns packaging into an entry point to your brand’s digital world.
3. Authentication and anti-counterfeiting
Each product receives a unique QR code. The consumer scans to verify authenticity. Critical for luxury brands, spirits, pharmaceuticals, and electronics, where counterfeiting represents significant revenue loss.
4. Technical documentation and after-sales
For industrial or electronic products, the QR code gives access to user manuals, installation guides, safety data sheets, or warranty registration forms. No more printing multilingual paper manuals: everything is online, in the consumer’s language.
5. Regulatory compliance and legal information
Limited space on the pack? The QR code links to complete nutritional information, allergens, usage conditions, or legal notices. It lets you meet regulatory obligations without cluttering the packaging design.
6. Data collection and analytics
Every scan generates data: location, time, device, frequency. These analytics reveal where, when, and how consumers interact with your products. Information that’s impossible to get from traditional packaging.
7. Multi-market management
The same packaging distributed across multiple countries can use a single dynamic QR code that redirects to content adapted to the consumer’s language or country. This simplifies production and logistics while delivering a localised experience.
How to Set Up QR Codes on Your Packaging
The setup follows four steps.
Step 1: Define the objective. What do you want the consumer to do after scanning? View a product page, sign up for a newsletter, verify authenticity, access a tutorial? The objective determines the content type and landing page.
Step 2: Create a dynamic QR code. Unlike a static QR code (which hardcodes a URL directly into the pattern), a dynamic QR code routes through a redirect server. You can change the destination at any time without reprinting. This is essential for packaging, where print runs are long and expensive.
Step 3: Customise and integrate into the design. The QR code should blend into the packaging design: brand colours, logo in the centre, frame with a call to action (“Scan to discover the origin”). A well-integrated QR code gets scanned 30% more often than a generic black-and-white code.
Step 4: Connect your analytics. Every scan should feed into your reporting tools. Set up tracking from the start to measure engagement, identify your most-scanned products, and optimise campaigns.
On Unitag, all four steps happen from a single interface. The QR code is created with your custom domain, styled to your brand, and analytics are available in real time.
Mistakes to Avoid
Using a static QR code. If the URL changes (site redesign, new campaign, error correction), you can’t update a static QR code. On packaging printed in large volumes, that’s a serious risk.
Ignoring size and placement. The QR code should be at least 1 cm x 1 cm, placed on a flat surface, with sufficient contrast against the background. A QR code that’s too small or poorly placed simply won’t get scanned.
Forgetting the call to action. A QR code without context gets ignored. Always add a line explaining what the consumer will find: “Scan to verify authenticity”, “Discover the recipe”, “Access your warranty”.
Not measuring. Without analytics, you don’t know whether your QR code gets scanned 10 times or 10,000 times. It’s like running an ad campaign without tracking the results.
FAQ
What’s the difference between a static and dynamic QR code?
A static QR code encodes the URL directly into the code pattern. It can’t be changed after printing. A dynamic QR code redirects through a server: the destination can be updated at any time without changing the printed code. For packaging, dynamic is essential.
What’s the minimum size for a QR code on packaging?
Minimum 1 cm x 1 cm, ideally between 1.5 and 2 cm per side. Size also depends on the intended scan distance and code complexity. Always test on the actual packaging material before committing to a full print run.
Do QR codes work on all smartphones?
Yes. Since 2017, both iOS and Android devices include a native QR code reader in the camera app. No third-party app is needed.
How do I prepare for GS1 Sunrise 2027 compliance?
Start with an audit of your current barcodes. Identify priority products for migration to QR code-based GS1 Digital Links. A dynamic QR code platform like Unitag lets you manage this transition progressively.
How much does it cost to add QR codes to packaging?
The printing cost of the QR code itself is negligible (it’s ink on packaging you’re already printing). The main cost is the dynamic QR code management platform, which varies by volume and features. Unitag offers plans suited to businesses of all sizes.
