Guiding principles
The GLN Management Rules provide an industry standard to create practical business value, specifically, when there is a need to identify a party or location for the first time or when predefined information changes that is associated to an existing party or location.
The following guiding principles should be considered when developing a GLN allocation strategy or when introducing changes to an existing party or location:

Does a stakeholder need to distinguish the changed or new party/location from previous/current party/location?

Is there a regulatory/liability disclosure requirement by the stakeholder?

Is there a substantial impact to the supply chain (e.g., where (or to/from whom) the product is shipped, stored, and/or received)?
At least one of the guiding principles must apply to require a new GLN to be allocated.
