The Global Data Synchonization Network, or GDSN, is an online network that allows partners to exchange product information in real time. The existence of the GDSN provides an authoritative data source, allowing trading partners to be confident that the data they have is up-to-date. The GDSN is made up of multiple master data pools, all of which are governed by GS1 standards. The network is supported by the GS1 Global Registry, which serves as a data directory and facilitates synchronisation.

GLN stands for Global Location Number. A GLN is an identification number used by companies in national and international business transactions. The GLN makes it possible to identify companies and parts of companies (such as locations and warehouses) worldwide, uniquely and without overlap. The GLN itself consists of 13 digits. This number can be used to call up company information via GS1 databases.

GS1 is a global, non-profit organisation that develops and maintains standards for electronic data interchange (EDI) in various industries, including retail, healthcare, and logistics. GS1's EDI standards are a set of globally recognised and adopted specifications that enable businesses to exchange standardised electronic messages, such as purchase orders, invoices, and shipment notices, with their trading partners. These standards are designed to ensure seamless and accurate data exchange, improve supply chain efficiency, and enhance business processes.

GTIN is the abbreviation for Global Trade Item Number. Colloquially, a GTIN is often referred to as a product's "article number". GTINs can be 8, 12, 13 or 14 digits long and are typically located below the barcode on products. The GTIN system was developed by GS1.
