The Electronic Product Code
(EPC) recognizes several EPC identities for the unique identification of goods, transport units or services. The Global Location Number (GLN), created by Global Standard One (GS1) Germany, formerly European Article Number
(EAN), and the Uniform Code Council, can be used to define the local, functional or physical unit within the EPC data frame. The Global Location Number is used in the Global Data Synchronization (GDS) and consists of 13 digits and indicates the trading location.
The first seven digits are assigned to the company, the following five identify the trading location and the last digit forms the checksum. The GLN code can be used to identify an infinite number of products, trading partners and their locations. It supports business to business (B2B) and business to consumer (B2C) concerns.
