The Global Location Number (GLN) is used to identify physical locations or legal entities. This unique identifier is comprised of a GS1 Company Prefix, Location Reference, and Check Digit.
As a GS1 Identification Key, the GLN will always be unique, thereby allowing trading parties to exchange GLN data for location identification with no danger of number duplication. A GLN can be assigned by a GS1 Company Prefix licensee anywhere in the world and can be used throughout the world.
