GS1 QR Code Ultimate Guide: Everything You Should Know

The GS1 QR code is a standardized two-dimensional barcode that conforms to GS1—an international organization that provides reliable, universally-recognized barcodes.

Two-dimensional barcodes, such as QR codes, have been popular for decades in many industries now, especially in logistics, manufacturing, and CPG (Consumer Packaged Goods).

Industries selling products must get a unique identification number from GS1 to sell products, whether online or in-store.

In this ultimate guide, we will dissect this technology to understand how a GS1 digital link QR code generator works and why it matters.

What does GS1 mean?

GS1 stands for Global Standards 1. It is an international non-profit organization that focuses on developing and maintaining global barcode standards and provides reliable, unique product identifiers.

These standards ensure that products, services, and information are identified consistently, making supply chain processes more efficient and transparent.

They are the official global provider of GTINs (Global Trade Item Number), EANs (European Article Number), and UPCs (Universal Product Code).

Understanding the GS1 digital link: Everything you need to know

GS1 digital link is a superset of product data. It is a combination of all unique product data, forming a unique product code link stored in a 2D barcode, following the global standard.

When you create a GS1 barcode, the input data is combined into one unique code. This is then stored in a QR code or data matrix barcode.

Now, let's dissect the digital link to further understand how do QR codes work when data is stored.

GS1 digital link follows a standard structure—the Uniform Resource Identifier (URI) syntax. Now, what does this even mean?

Well, technically, a single GS1 code comprises of these data:

  • Domain
  • Primary Identification Key
  • Key Qualifiers
  • Data Attributes

Once you input all these data, you can get your GS1 digital link with the combined data.

GS1 QR code example

Here’s a GS1 digital link example:

Gs1 QR code

This combined GS1 digital link is then encoded to a data carrier, such as a QR code or data matrix barcode. Once scanned, the resolver receives the URI, leading you to the stored information.

Using the GS1 QR code or data matrix barcode, you’re not just giving your product a unique digital identity but also creating a handy digital portal for your brand and new consumer experiences.

And this is the power of 2D barcodes, especially QR codes. In a quick scan using a smartphone, you can unlock invaluable information.

These tiny codes can deliver more than a handful of information right at your fingertips in just a snap.

GS1 digital link layer cake

Let’s dive into the technicalities and uncover the layered architecture behind a GS1 digital link. This will help us understand how the link is created and converted into a scannable code to retrieve the stored data.

A single GS1 QR code or barcode combines several data, including:

GS1 digital link URI structure

A GS1 digital link relies on a Uniform Resource Identifier (URI) to connect physical products with online information.

A URI is a set of unique product values. It follows a standard structure to form a distinct link address:

  • Web domain

This refers to your website link or web address.

  • Product primary identification key

This refers to the Application Identifier (AI). Examples include GTIN, SSCC (Serial Shipping Container Code), and GCN (Global Coupon Number). It serves as the initial code attached to the website link address.

  • Unique identifier

This unique digit value refers to the product’s unique identification number based on the AI key.

  • Product’s key qualifiers

Depending on the AI key, this one’s an optional addition to specify products accurately.

For GTINs, it includes consumer product variants, batch or lot numbers, and serial numbers.

  • Data attributes

This refers to particular product specifications such as dimension, weight, expiration, manufacturing date, and more.

Once you have entered all values into the system, you can then extract the combined web address.

Link types

Link type simply refers to the information or content type based on the topic or category. Examples of link types include:

  • Product information page
  • Nutritional facts
  • Digital product passport
  • Inventory status
  • Usage instructions
  • Product guide
  • Clinical information


Resolvers are the translators or decoders of the digital link or URI. Technically, they are servers in charge of bridging the product and digital information.

Upon scanning a GS1 digital link QR code, the resolvers decode the URI and analyze the unique product identity based on the identifiers.

Resolvers perform these functions:

  • Decompress data
  • Validate product identifiers
  • Translate the stored information

Simply put, resolvers provide access to multiple, relevant content. They redirect the scanner to the appropriate link or content based on the digital link behavior (who, where, and how they scanned).

With a resolver, you can link to different links or content all at once. So, a single GS1 digital link can work for various purposes, thanks to the resolver services.

To understand it better, here’s a scenario:

When a cashier scans a GS1 digital link QR code at checkout, the resolver leads to pricing and inventory information.

But when scanned by a consumer using a smartphone, the resolver leads to the product video or special offer.

Your QR code won’t need a resolver. However, the digital link can only redirect to a single piece of information.

Data carriers

Once you generate the GS1 digital link URI, you must encode this to an optical data carrier to attach it to the products.

You can use QR codes or a data matrix—popular 2D barcode types. Data-wise, QR codes can store bigger data sizes since they have bigger size ranges.

The minimum QR code size has 21×21 cells, while a data matrix has 10×10 cells.

A maximum QR code size with 177×177 modules can contain 7,089 numeric characters or 4,269 alphanumeric ones. Meanwhile, a maximum data matrix code size only has 144×144 cells.

Plus, QR codes are omnidirectional and super easy to access using a smartphone—no specialized devices are needed.

That’s why QR codes are the ideal choice. On top of that, QR codes can now contain more than just links.

QR TIGER’s dynamic QR codes can also store files like videos, audio, images, and documents. You can even create your customized landing page and store it within the code.


All users, including businesses or organizations, can use third-party applications or software. They can also develop their own digital link-based applications to serve their unique business purposes.

Linked data

It refers to the data source or the information stored in the data carrier, such as the product identifier, key qualifiers, and attributes.

Since the product data is compressed in a single code, of course, they need to be translated into a human-readable resource.

This data is structured following the GS1 standards, so they’re machine-readable.

What is the purpose of the GS1 barcode?

The GS1 2D barcodes serve as unique identifiers for products. They streamline supply chain operations, minimizing errors and enhancing traceability.

GS1 barcodes, including GS1 data matrix and QR codes, are universally recognized and globally renowned product codes.

They allow users, businesses, and organizations to automatically identify, track, and manage their products throughout the supply chain more efficiently. These boost the supply chain’s transparency, efficiency, and accuracy.

These advanced capacities have led to GS1’s conception of the Sunrise 2027 project, which aims to provide standardized 2D barcodes that are more effective for the supply chain and consumers.

One-dimensional barcode has offered price lookup functionality for decades. However, it no longer meets today’s growing demands for greater product information transparency, traceability, and authentication,” GS1 clarifies.

With GS1’s initiative and the skyrocketing QR code usage statistics, it’s now much more possible that QR codes will replace barcodes in the coming years.

What makes QR codes ideal for businesses


With QR codes, you don’t need to use a specialized device or scanner. If you have a smartphone—which almost everyone now has—you’re good to go.

BankMyCell’s January 2024 report revealed that there are 6.93 billion smartphone users worldwide—that’s 85.74% of the world’s population.

With this high number, it’s imperative for industries to adopt a mobile-first strategy.

This is the advantage of QR code technology: People can access information using smartphones in just a few seconds.
