What is a Goods Movement Reference (GMR)?
A Goods Movement Reference (GMR) is a unique reference number used in the UK’s Goods Vehicle Movement Service (GVMS) to link all customs declarations for goods in a single vehicle. It is required for moving goods through roll-on/roll-off (RoRo) ports and must be created before arrival at the port.
In practical terms, a GMR acts as a single digital reference for an entire load, allowing it to move efficiently through UK border controls.
At Efret, we help clients navigate UK customs requirements every day. This guide explains everything you need to know about GMRs in a clear, practical way.
Why is a GMR important?
A GMR is critical because it enables:
- Faster processing at UK ports
- Pre-lodged customs clearance before arrival
- Reduced congestion at key crossings like Dover and Eurotunnel
- Seamless handling of multiple consignments in one vehicle
Without a valid GMR, vehicles are typically refused boarding, causing costly delays.
Who is responsible for creating a GMR?
Responsibility usually sits with the European transport provider moving the goods.
This could include:
- Freight forwarders
- Transport operators managing cross-border shipments
At Efret, we often support customers by coordinating this process to ensure compliance.
What information is needed to create a GMR?
To generate a GMR, you’ll need:
- Customs declaration references (MRNs)
- Transit document references (if applicable)
- Vehicle registration number (VRN) or trailer ID / plate number
- Crossing details (port and route)
A single GMR can cover multiple consignments, provided they are all on the same vehicle.
How is a GMR created?
GMRs are created via the GVMS platform managed by HM Revenue & Customs.
Step-by-step:
- Register for GVMS
- Log into the system
- Input all declaration references (MRNs, transit docs)
- Enter vehicle or trailer details
- Generate the GMR
The system will produce a barcode, which the driver presents at the port.
When should a GMR be created?
Timing is crucial.
- Exports from the UK: Create before arriving at the port
- Imports into the UK: Create before boarding in the EU
If the GMR is not valid at check-in, the vehicle will not be allowed to travel.
What happens after a GMR is submitted?
Once a GMR is created and used at check-in:
- GVMS links all declarations to the vehicle
- UK border systems assess the shipment automatically
- The driver is instructed to either:
- Proceed directly, or
- Report for inspection
This process reduces the need for manual document checks at the border.
What happens if a GMR is missing or incorrect?
Failure to provide a valid GMR can result in:
- Refusal of boarding at the port
- Significant shipment delays
- Additional storage and transport costs
- Potential compliance penalties
Accuracy is essential - small errors can disrupt entire supply chains.
What is the difference between a GMR and an MRN?
Understanding the distinction is key:
- MRN (Movement Reference Number):
A reference for an individual customs declaration - GMR (Goods Movement Reference):
A single reference linking all declarations for one vehicle
Think of the GMR as the umbrella reference for the entire journey.
Which ports require a GMR?
GMRs are required at many major UK ports operating under GVMS, including:
- Dover, Eurotunnel (Folkestone), Newhaven, Holyhead, Liverpool*

Do all shipments need a GMR?
No. GMRs are mainly required for roll-on/roll-off (RoRo) traffic.
They are typically not required for:
- Container shipping via non-GVMS ports
- Air freight
- Inventory-linked port movements
