Currently, a GLN that has been previously used and has become obsolete must not be reused for another location until at least 48 months have elapsed, except for locations used in the healthcare supply chain, where issuers of GLNs must ensure that GLNs shall never be reused, e.g., locations where treatment of patients takes place etc.
From July 2022 onwards, GLN Non-reuse will be applicable to ALL industries. An alert/notification (as per below) will be included in the next version of the General Specification in January 2022, giving all stakeholders time to update their systems and processes.
Important: The standard for GLN reuse will be changed on 1 July 2022. On that date, a GLN allocated to a party and/or location SHALL NOT be reallocated to another party and/or location. It is recommended that GLN reuse cease in advance of 1 July 2022 as soon as companies can transition their practices. If reuse is not currently occurring, it SHOULD not be started.
The only exceptions to the GLN non-reuse rules will include:
If the GLN was never published in an externally accessible manner (e.g., to a registry or directly to a trading partner), it may be reused immediately.
Parties and/or locations that have been withdrawn and are reintroduced may use the original GLN if they are reintroduced without any modifications or changes that require a new GLN as specified by the GS1 GLN Allocation Rules Standard.
