France's ELO (Obligatory Logistics Envelope): The Mandatory Port Pass for GB–FR Freight
Cross-channel trade has faced its biggest operational shift since Brexit. Since 20 April 2026, France has strictly enforced the Obligatory Logistics Envelope (ELO) for freight crossing the Smart Border between Great Britain and France, in both directions.
The system was available for optional use from April 2025, and the move to a mandatory requirement marked a critical turning point. If you are a haulier, freight forwarder or customs agent, the "wait and see" period is over.
This guide covers everything you need to know about the ELO, how it compares to GVMS, and the steps you must take to ensure your vehicles aren't stuck at the border.
What is the Obligatory Logistics Envelope (ELO)?
Think of the ELO as a digital port pass for France. It is designed to bundle every piece of data French customs requires into a single, scannable barcode.
Before the ELO, drivers often presented a patchwork of paper documents, MRNs and safety references. The ELO consolidates all of this into one digital "envelope". It acts as the French equivalent to the UK's Goods Vehicle Movement Service (GVMS).
The ELO serves two main functions:
- Validation: It ensures all customs processes (including Safety & Security declarations) are complete before the vehicle arrives at the port.
- Trigger: It automatically updates the status of customs procedures upon arrival, replacing manual questions at the check-in booth.
Key dates: when did ELO become mandatory?
- Available since April 2025: The ELO online service opened on 28 April 2025, and early adopters used it to streamline crossings.
- Mandatory since 20 April 2026: From this date onward, the ELO is no longer optional. Vehicles without a valid ELO barcode may be refused boarding or face significant delays at French RoRo ports (such as Calais, Dunkirk, Le Havre and the Channel Tunnel).

Tip: If you haven't set up ELO yet, do it before your next crossing. Getting used to the system early lets you troubleshoot issues before they hold up a vehicle.
How the ELO process works
The ELO is part of France's "Smart Border" system. It integrates directly with ICS2 (Import Control System 2), meaning strict data alignment is required. Here is the workflow:
1. Creation (pre-journey)
An authorised party (haulier, forwarder or customs broker) logs into the French customs portal. They must link the following data to a specific vehicle:
- Vehicle and driver details.
- Customs declaration references (import/transit).
- ENS (Entry Summary Declaration): For loaded vehicles entering France, the ELO requires an ICS2 ENS filing (only ICS2 ENS filings can be added). We recommend using ENS Ready to create the ICS2 declaration.
2. The check-in
When the driver arrives at the ferry terminal or shuttle, they present two barcodes:
- The GMR (for UK customs).
- The ELO (for French customs).
Because the data is pre-validated, the driver no longer needs to answer complex questions from ferry operators regarding the cargo status.
3. The crossing and risk analysis
While the vessel is crossing the Channel, French authorities perform a risk analysis based on the ELO data.
4. Arrival (green vs orange lane)
Upon disembarking in France, the driver looks for their status on the digital screens:
- 🟢 Green lane: No risks identified. The vehicle is cleared to exit the port and continue its journey.
- 🟠 Orange lane: Documents need checking or a physical inspection is required. The driver must report to the customs office at the point of entry.
Why is France introducing ELO?
While it requires new administrative workflows, the ELO is designed to solve the congestion caused by post-Brexit border checks.
- Speed: By removing manual document checks at the entry booth, queue times are drastically reduced.
- Accuracy: The system "pairs" documents digitally. This prevents the common error of drivers presenting the wrong paperwork for the wrong load.
- Visibility: The ELO creator gets enhanced visibility into the shipment's progress (pairing, embarkation and disembarkation), though they must still communicate with the driver to know if they hit the orange or green lane.
How to prepare your business
The smartest operators treat the ELO as a standard operating procedure for every crossing.
- Appoint an ELO creator: Decide who is responsible. Is it your internal logistics team or your customs broker?
- Ensure ICS2 compliance: Since the ELO relies on Safety & Security data, you must be fully compliant with ICS2 filing requirements.
- Train your drivers: Drivers need to understand that the ELO barcode is as vital as their passport. They must know how to present it alongside their GMR.
- Digitise your workflow: If you are still relying on physical paperwork to track shipments, the ELO will be difficult to manage. Move to digital record-keeping to ensure reference numbers are easily accessible for the envelope creation.
Questions
What is the ELO?
The Obligatory Logistics Envelope (ELO) is French Customs' digital port pass. It bundles the customs and safety and security references for one vehicle into a single, scannable barcode, which the driver presents at check-in alongside the GMR.
When did the ELO become mandatory?
The ELO has been available since April 2025 and became mandatory on 20 April 2026. A vehicle without one can be refused boarding or sent to the orange lane on arrival in France.
Does the ELO need an ICS2 ENS?
Yes, for loaded vehicles entering France. Only ICS2 ENS filings can be added to an ELO, so the ENS must be filed in ICS2 before the envelope is completed.
