Definition & Explanation

The Goods Declaration Reference Number (GDRN) is the key that links a submitted customs declaration to all subsequent actions in the electronic customs system. Assigned automatically upon registration, it appears on every official communication tied to that filing—queries, inspection notices, rulings, and the final release document. In cross-border shipments, freight forwarders and consignees use the GDRN to coordinate with customs and avoid hold-ups caused by missing references. It should not be confused with the MRN (Movement Reference Number), which serves a distinct role in transit procedures under European customs law.
