New Zealand Business Number is a GLN

Each kiwi business is identified with a New Zealand Business Number (NZBN), which is a GLN. The GLN was chosen as the unique identifier by the Government as it's an ISO (International Organisation for Standardisation) standard, and part of a credible international system used in international trade, supply chain logistics, and eCommerce.

In addition to helping businesses automate exchanges of information, the NZBN is now deployed in e-invoicing and e-procurement.
