GS1 Global Location Number (GLN)

GS1 Global Location Number                                                     CAS * 


The GS1 Global Location Number (GLN) is a 13-digit globally unique identification code that is assigned by GS1 Canada to identify:

  • Legal entities, such as provincial health authority, hospitals, manufacturers, or shared services organizations, among many others.
  • Functions within legal entities, such as hospital pharmacy or accounting departments; and
  • Physical locations, such as a hospital wing, nursing station or manufacturer’s warehouse, or delivery point address.
  • Type of location, such as a health system, clinic, manufacturing centre.

The GLN is designed to improve the accuracy and efficiency of communication between and within organizations, and as such, add value to these organizations through improving operational efficiencies, cost savings, as well as to increase patient safety.

The use of GLNs help healthcare organizations to:

  • Improve staff productivity by transitioning from maintenance of proprietary identification codes thus enabling staff to spend more time with patients and less time on manual documentation.
  • Improve information quality by providing unique party/location identifier that can be used in both internal and external documents and processes.
  • Enhance product recall and traceability by uniquely identifying the location of each product.
  • Improve process inefficiencies.

* Status Definitions

Canadian Draft for Use (CDFU) - The standard has been developed but it may or may not be implemented or be in use. The standard is considered ready to be used by early adopters: however, change is probable as stakeholders begin using the standard in implementations.

Canadian Approved Standards (CAS) - The standard is in use for the purpose(s) or context(s) for which it was intended. Only those parts of the standard that have been implemented or are in use can progress for consideration as CAS. This decision point signifies that the standard has reached a level of stability and is comprehensive enough such that major changes are not expected.
