MRN number – What you need to know about the Movement Reference Number in transport
In the world of international trade and transport, the Movement Reference Number (MRN number) is an essential part of the customs process. The MRN is important for a proper customs declaration and delivery.
What is an MRN number?
An MRN number is a unique identification number assigned to a customs declaration. It is automatically generated when you register a shipment in the customs system. This number is important for tracking your shipments and managing customs procedures. The MRN number enables customs authorities to check and verify the customs status of shipments.
Why is the MRN number important?
- Efficient Customs Declaration: When submitting a customs declaration for export or transit, the MRN number is required. It helps to register the shipment in the customs database, which can significantly reduce processing time.
- Tracking Shipments: With the MRN number, both importers and exporters can track their shipments in real-time. This number is vital for monitoring the status of goods during customs transit.
- Control of Taxes and Duties: The MRN number is essential for calculating import duties and taxes associated with the shipment. This makes it important to ensure that everything is correctly registered.
- Country Code and Customs Requirements: The MRN number contains information about the country code and other details relevant to customs in the destination country, which helps in complying with local customs requirements.
How does the MRN number work?
When submitting a customs declaration for shipments, such as by truck, container, or trailer, the customs system automatically generates an MRN number. This number must be stated on various customs documents to ensure smooth processing. For example, if you are shipping goods from the United Kingdom to the European Union, the MRN number is an important part of the export procedure.
Checking an MRN number
You can easily check the MRN number via official customs websites or by contacting your customs agent. This allows you to verify the status of your shipment and ensure that everything has been handled correctly. Checking an MRN number can also be useful for detecting any potential customs issues early on.
