Securely exchange, synchronize and benefit from data with GDSN®.

You have a good product that wants to go on sale? Then it's high time to give it a place in the front ranks. But whether you want to place your product in retail, online marketplaces, in Germany, or Spain: What you need is a platform for product content that enables digital data exchange via GDSN®. With GDSN®, master data can be efficiently exchanged between business partners around the globe and automatically kept in sync.

This saves time, reduces costs and avoids errors.

GS1 GDSN®- the network for product information

The GS1 Global Data Synchronization Network( GS1 GDSN®) has been in existence since 2004 and is the world's largest network for product information. Taking into account mandatory legal requirements, the GS1 GDSN® enables any company in any market to seamlessly exchange high-quality product information. All data is stored centrally in a GS1 GDSN® data pool and can be synchronized via this. This benefits both the data sender and the data recipient, and of course the shopper as well.

Manufacturers record their product information once in a single, central data pool - even if the items are to be placed in Spain or overseas. In addition, suppliers create a central catalog for quality-checked product data within the company.

All product master data is made available to retailers at a central location - and this is completely independent of the manufacturer. This data can then be retrieved for a wide variety of purposes (e-commerce, retail, app, print, etc.).

Secure success thanks to established standards.

Retailers need product information such as designation, dimensions and weight for all business processes (purchasing, logistics, disposition, sales, etc.). And in addition, legal requirements must be met, which neither young start-ups nor large brand manufacturers can avoid. Therefore, product master data must be prepared and optimized in such a way that it complies with EU regulations and at the same time satisfies customers and retailers.

The GDSN is a globally operating standardized network around which a number of GS1-certified data pools revolve. In these data pools, the data is ready for digital exchange via GS1 GDSN. To ensure that everything runs smoothly, the data pools have standardized data sets. This ensures that data senders and data receivers can exchange and synchronize relevant information in real time anywhere in the world: If, for example, a data sender changes the dimensions of its product, the data recipient (e.g. a retail company) is informed immediately.

Data acquisition on demand, atrify

Article information is essential in many respects

Let's take a look at logistics in retail. Here, the central role of item information quickly becomes apparent: Every day, trucks are loaded to supply the grocery trade with new goods. And each time, it is calculated exactly how much transport capacity is available. For this purpose, information regarding the dimensions is required, from which the volume and thus the exact number of trucks required can be calculated. Inaccurate measurements or missing information are fatal for route planning and often end in additional tours or transport areas remain unused.

More efficiency: standardized information in use globally

With the globalization of trade and the economy, new markets are opening up for companies. Thus, not only one target market can be supplied, but many. The international GS1 standard offers a strong and solid foundation here, so that your product data can be exchanged across countries and in a comprehensible way. From a technical point of view, the GS1 GDSN works with standardized information units (so-called attributes) such as the "item description". This way, every manufacturer and retailer worldwide knows that this is the description of the product - and not, for example, a marketing text. There are also industry-specific attributes, for example for the food industry. In this case, these would be attributes for certain types of nutrition, defining values such as gluten-free, vegan, vegetarian, suitable for diabetics, but also halal or kosher.

Global Registry: Search and find articles worldwide.

When all supermarket chains store their products in a data pool, the result is a gigantic directory of articles, data senders and data recipients. And to make searching for a specific item as easy as possible, there is the Global Registry. A gigantic directory of information that, like a worldwide telephone book, uniquely identifies every single article and every party.

To determine the uniqueness of registered items and parties, a few identifiers (key information) are sufficient:

the Global Location Number (GLN)

The GLN is a thirteen-digit GS1 identification number. It is individual like a corporate fingerprint that can be used to uniquely identify each location in the supply chain. The Global Location Number can be assigned to a physical location (such as a production facility) or to a legal entity, such as a manufacturer.

Structure & composition of the GLN

  • GS1 company prefix: this is assigned by GS1 member organization
  • Location reference: it is assigned to companies to a specific location
  • Check digit: the digit is calculated according to a standard algorithm. It helps to ensure that the uniqueness.
the Global Trade Item Number (GTIN, formerly EAN)

The GTIN is a unique product ID. It consists of 14 numeric characters that identify not only the article itself, but also its packaging units. In other words, the basic article, the carton or the pallet. Important to know: A GTIN can be used to map separate item entries for the same product at different packaging levels. The GTIN can be encoded by barcode or RFID tag. By reading the barcode or RFID tag, companies are able to process information about products efficiently and centrally. For example, in the logistics area or at the checkout in the supermarket.

GTIN structure & layout

  • Indicator digit: used to indicate the level of packaging (1 digit).
  • Company Prefix: this is the Global Company Prefix, CCP.
  • Article reference number: created by the company
  • Check digit: the last digit to ensure the uniqueness of the GTIN.
the Target Market (country code for target market)

The Target Market is a country code. This identifies the country in which the article is sold. Why is this number required? Some products are sold in different countries and use the same barcodes. Yet there are product differences for the specific target markets. This is exactly what the Target Market is all about.

  • Identifies the country where the item is to be traded.
  • ISO 3166-1 Country Code List (3-digit number e.g. 756=Switzerland)
  • Enables the implementation of target market specific validations.
the Global Product Classification code (GPC code)

Each product class is identified by a unique GPC code. The Global Product Classification (GPC) standard helps trading partners group products in the same way anywhere in the world. The standard is clear and internationally understandable.

GS1 GDSN Glossary

What is article master data?

Article master data is information about products and their properties that is exchanged between trading partners. In a modern logistics chain, master data in electronic form is indispensable and a prerequisite for the product listing process of most retail companies - in other words, for being included in the range of products offered by a retail chain.

How is article master data transmitted?

atrify uses the Global Data Synchronization Network - GDSN for short - to transmit master data. All product data is stored, managed and released centrally in a data pool. You can make your product information available to all connected trading partners or select individual ones (for example, by target market or GLN).

What is the GDSN?

GDSN stands for Global Data Synchronisation Network (GDSN). With the GDSN, product master data is exchanged globally between manufacturers and distributors. The data only needs to be entered into one single data pool. The GDSN connects 30 certified data pools worldwide to which almost 25,000 companies are connected. There are key fields to uniquely identify articles in the GDSN. Some of these key fields are the GTIN, the GLN (Global Location Number), the Target Market (TM), and the Global Product Classification (GPC).

What is a product listing?

A product listing is an entry in the catalogue of a retailer. Nowadays, master data is provided almost exclusively in electronic form. This is usually a prerequisite for a listing with large retail chains in order to be included in the goods catalog. With atrify publishing you can provide the trade with the data in the desired form centrally with only one database.

What is a GTIN and where can I get it?

The GTIN is a unique product ID. It consists of 14 numeric characters that identify not only the article itself, but also its packaging units. This means the basic article, the carton or the pallet. Important to know: With a GTIN, separate article entries for the same product can be displayed on different packaging levels. The GTIN is encoded by barcode. By reading the barcode, companies are able to process information about products efficiently and centrally. You need a GTIN for the electronic master data exchange and is required by many retail chains for a listing.

A GTIN can be ordered quickly and easily on the GS1 Germany website.

What is a target market?

A Target Market is a clearly delineated area and defines where a manufacturer places its products on the market. To identify which country an article should be traded in, a country code is used, the so-called Target Market.
