GS1 Digital Link QR codes on your own domain

A GS1 Digital Link is a web address that carries barcode data. The GTIN your product already has goes into the path, optional details such as a batch number or serial follow it, and dates or weights ride along as query parameters. Encode that address in a QR code and one symbol serves two readers at once.

The numbers in brackets are GS1 Application Identifiers, the same ones used inside every retail barcode today. A register that supports 2D codes reads the GTIN out of the path and rings the item up. A phone opens the address, and the resolver behind it decides what the shopper sees.

This is the part that changes packaging. Today a pack carries a linear barcode for the register and, often, a separate QR code for marketing. A digital link folds both into one symbol. The register never follows the link, it only needs the GTIN. The phone never sees the GTIN, it only follows the link. Each reader takes the half it understands.

Because the destination lives behind the resolver rather than inside the code, the page a shopper lands on can change for as long as the product is on shelves. Recall notices, seasonal campaigns, a new instructions page, a per-country variant: none of it needs a reprint.

KuikPage · link · PDF · rules

Turn on GS1 Digital Link in the editor, enter the GTIN, and the code updates as you type. Everything below is part of that one destination type.

GTIN validated as you type

GTIN-8, 12, 13 and 14 with the check digit verified live, normalised to the 14-digit form the standard expects.

Batch, serial and variant

Lot (10), serial (21) and consumer product variant (22) in the order the standard mandates, each one optional.

Application Identifier attributes

Expiry, packaging, best-before and sell-by dates, country of origin, net weight, item count, and any custom AI you need, each checked against its GS1 format as you type.

Human-readable line, on by default

The (01)09506000134352 line GS1 requires next to the symbol prints under the code as part of its frame, so a cashier can key it in if the scan fails.

Your own host

An included GS1 host on kuikco.de from the first code, or your branded subdomain and custom domain. The GTIN is unique inside your workspace, never shared with strangers on a common domain.

Editable phone destination

A link, a KuikPage you build here, a PDF, or smart rules by country, language, device and time. Change it after printing. The register never notices.

Bulk from a CSV

One row per product with GTIN, qualifiers and attribute columns. Every row is validated, duplicates are caught before anything is created, and the whole batch shares one design.

EAN-13 and Data Matrix companions

Download the linear barcode and the GS1 Data Matrix of the same GTIN beside the QR, for the panels and labels that still need them.

Analytics and webhooks

Every phone scan lands in realtime analytics with city, device and language, and can be forwarded to your systems through scan webhooks.

GS1 Digital Link QR

Phones and 2D registers. The one that carries your brand.

EAN-13

The same GTIN as a linear barcode, for lanes that still read 1D.

GS1 Data Matrix

Element strings for regulated labelling and supply chain marks.

A digital link is only as useful as the resolver behind it. Retailer apps, marketplaces and partner systems do not want a redirect, they want to ask a product what links it offers. KuikCode's resolver answers in the standard way on every host you own.

Every redirect carries a Link header listing the same typed links, and each host publishes its resolver description at /.well-known/gs1resolver. Those responses are public, so a buyer or a compliance team can verify them without an account. Machine requests for the linkset are never counted as scans, so your analytics keep measuring people.

GS1's Sunrise 2027 programme asks retailers to be able to read 2D barcodes at the point of sale by the end of 2027. It does not order anyone to remove linear barcodes, and GS1 itself describes the transition as an ambition for the industry rather than a switch-off date. What it does mean is that packaging designed today should carry a 2D code that registers can use, and that code should be a GS1 Digital Link so the same symbol works for shoppers.

Grocery chains in Australia, convenience stores in Thailand and delis in Brazil have already rung up digital links at the register. The sensible path for a brand is the one those pilots took: put the digital link next to the existing barcode on a few products, confirm your scanners read it, then widen the rollout as packaging cycles come up.

Consumer packaged goods, food and beverage, cosmetics and household brands that print barcodes on packaging and want the marketing side of the same symbol. Manufacturers with batch and serial traceability requirements. Healthcare and pharma teams, where the GS1 Data Matrix companion carries the same element strings for regulated labelling. Agencies and packaging studios doing this for several clients from one workspace.
