GS1 Digital Link Explained: What Every Brand Needs to Know Before Sunrise 2027

I'll be honest — I ignored Sunrise 2027 for a long time. Two years, roughly. The barcode industry kept talking about it at every trade show, every webinar, every LinkedIn post from people with "supply chain" in their title. And every time I thought: that's a Unilever problem. A Procter & Gamble problem. Not a problem for a company running forty SKUs out of a warehouse on an industrial estate.

Then I watched a Carrefour store in France swap out its checkout scanners. Not some pilot program. The actual store, the actual checkout lanes. And that's when it stopped being abstract.

If you put a product on a shelf — any shelf, any country — keep reading.

Give me the short version

Alright. By late 2027, most big-name retailers will be able to scan a QR code at the till instead of (or alongside) the traditional barcode. That QR code carries way more data than those old black lines ever could. And eventually — not tomorrow, but eventually — retailers will stop asking nicely and start requiring it.

That's the whole thing. Everything below is the how and the why.

The barcode's fifty-year run is winding down

The barcode on your cereal box? Invented in 1974. It does one thing: encodes a number. The cash register looks that number up in a database. Price, name, tax category. Done.

Fifty years. That's how long we've been scanning those lines. And for most of that time, a number was all anyone needed.

But think about what a modern supply chain actually wants to know. Where was this thing manufactured? Which batch? When does it expire? Has it been recalled? What allergens? What's the carbon footprint of the packaging? (Yeah, that last one is a thing now — the EU's Digital Product Passport isn't messing around.)

A traditional barcode can't carry any of that. It's literally just a number dressed up as lines. A dumb key to a dumb lock — I keep coming back to that metaphor because nothing else captures it as well.

A 2D code — a QR code built on GS1's data structure — can carry all of it. Inside the code itself. Not in some database that might be down, stale, or locked behind someone else's login.

So what is GS1 Digital Link, exactly?

Okay, I'm going to explain this the way I wish someone had explained it to me, because the official GS1 documentation reads like it was written by a committee. (It was.)

GS1 Digital Link turns your product's barcode data into a web address. That's the core idea.

Instead of encoding just 5901234123457 — a plain EAN-13 number — a Digital Link QR code encodes a URL:

https://id.gs1.org/01/05901234123457/10/ABC123/21/12345

Break it apart:

• 01/05901234123457 — the GTIN. Same number that's on your barcode today.
• 10/ABC123 — batch or lot number.
• 21/12345 — a serial number unique to this individual unit.

When a retail scanner hits that code, it strips out the GTIN and rings up the sale. Business as usual. But when a shopper scans the exact same code with their phone camera — they get sent to a web page. Product info, sustainability data, recipe ideas, allergen lists, whatever the brand wants to show.

One code, two completely different experiences depending on who's scanning. That's genuinely clever, and it's the reason the whole industry is getting behind it.

"Hold on — I already have QR codes on my packaging"

Maybe you do. And I'd bet they link to your website homepage or — let's be real — an Instagram page that hasn't been updated since March.

That's a marketing QR code. It is not a GS1 Digital Link.

The difference is structure. A Digital Link follows a specific URI format with your GTIN baked in. A POS scanner can parse it and extract the product number. A random QR code pointing to yoursite.com/summer-sale? The checkout scanner looks at it and goes — I have no idea what product this is. It just… ignores it.

So no. Slapping a QR code on the box and moving on won't work here. The code needs GS1 Digital Link syntax or it's invisible at the till.

What "Sunrise 2027" actually is (and isn't)

I want to be direct about this because there's a lot of FUD floating around.

It is not a law. There is no regulation. Nobody's going to fine you on January 1st, 2028 because your cereal box still has an EAN-13 and nothing else. Breathe.

It is an industry commitment. GS1 and the world's biggest retailers — Walmart, Carrefour, Tesco, Kroger, Woolworths, and a growing list — have agreed that by end of 2027, their POS systems will be capable of reading 2D codes. The hardware will be there. The software will be there.

And then what? Well, this is how these things always play out. First the capability exists. Then "guidelines" appear. Then the guidelines quietly become requirements. And one morning you get an email from a category buyer at Tesco saying "we need a GS1 Digital Link QR on the next packaging run or we're reviewing the listing."

I've seen this pattern play out with nutrition labeling, with allergen declarations, with FSMA compliance. It always starts as "optional" and ends as table stakes. Plan accordingly.

The practical bit: what to actually do

Right, enough context. Here's what I'd do — and I'm writing this specifically for small and mid-sized brands without a dedicated packaging engineer or a compliance department. If that's you, this section is the one to bookmark.

Between now and the end of 2026

Start with your GTINs. Seriously, before anything else. Do you actually have properly registered GS1 numbers for every product? Or did you buy a batch of "cheap barcodes" from some reseller eight years ago and never think about it again? Because if it's the latter — and I say this without judgment, a lot of people did it — those numbers don't trace back to you in the GS1 database. Fix it now while there's no pressure. (Here's the full walkthrough on getting a GS1 prefix.)

Get your batch data under control. Lot numbers, expiry dates — if they're living in a spreadsheet that Karen updates when she remembers, that's not going to cut it when you need to encode them into every QR code on every unit. Pick a system. Any system. Just make it consistent.

Call your packaging supplier. Not email — call. Ask how much lead time a layout change needs. I was stunned to learn mine needed fourteen weeks for a flexo print change. Fourteen weeks! If you're planning a packaging refresh anyway, this is the time to work the QR placement into the design.

And check your scanners, if you run a shop floor or your own fulfilment. Laser scanners — the classic red-line ones — physically cannot read a QR code. You need an image-based reader. (This piece explains the difference.)

Early 2027: put it on the packaging

Generate your QR codes with GTIN data embedded. You can do this on BarcodeReady — export as SVG or PDF so the print stays razor-sharp at any scale. Don't use a PNG screenshot you grabbed from somewhere. Please.

During the transition — and this will last a while — use dual marking. Both the old 1D barcode and the new 2D code, right there on the same panel. Your product needs to scan at stores that have upgraded and stores that haven't. GS1 says keep them within 50mm of each other to avoid double-ring situations at checkout.

Late 2027 and beyond

Once the basic QR-with-GTIN is working, start layering in additional data — batch numbers, serial numbers, expiration dates. The beauty of Digital Link is that you can add these progressively. You don't have to do everything on day one.

Build a resolver. (Fancy word for: make the URL in your QR code actually go somewhere useful.) Product pages, ingredient lists, sustainability reports, recall notices. If someone scans your code and gets a 404 error… yeah. Don't be that brand.

And stay in touch with your retail buyers. Each chain will set its own timeline for when 2D becomes required. There won't be one universal date — it'll be a rolling wave.

"This doesn't apply to me. I'm small."

I hear this a lot. "I sell handmade candles on Etsy and at the farmers' market. I'm not going into Walmart."

And look — if that's genuinely your plan, you're right. This doesn't affect you yet. Keep using Code 128 with your internal SKUs, keep printing labels on your Dymo, and sleep easy. (Quick guide on choosing the right barcode format here.)

But if there's even a 20% chance you'll pitch to a regional chain someday — a small grocery group, a gift shop distributor, anyone with a POS system — do yourself a favour and get ahead of this. The brand that walks in with GS1 Digital Link–ready packaging is going to look sharp next to the one still explaining why their barcodes are from a reseller that went dark in 2019.

Buyers notice that stuff. Trust me.

So — bottom line?

Sunrise 2027 isn't a fire alarm. It's a weather forecast. The storm is coming, but you've got time to board up the windows.

Get your GTINs clean. Get your GS1 registration legit. Start tracking batches properly. And make sure your next packaging run has room for a QR code — even if you don't fill it yet.

When the switch flips, you'll be the one who saw it coming.
