Yes, there are two exceptions.
1. If a GTIN has been assigned to an item, which was then never actually produced, the GTIN may be deleted from any catalog immediately without first being marked as discontinued. In this exceptional case, the GTIN may be reused 12 months after deletion from the seller’s catalog.
2. Trade items that have been withdrawn from the market and are reintroduced may use the original GTIN if they are reintroduced without any modifications or changes that require a new GTIN as specified by the GTIN Management Standard.
