EORI NUMBERS: WHAT’S CHANGING IN 2025

March 26, 2025 | Theme: Regulation

2025 marks a key stage in the evolution of French customs procedures, with the widespread introduction of the EORI-SIREN number and the new DELTA I/E system. These changes are designed to simplify customs formalities, improve the traceability of trade and enhance the digitization of procedures. What do you need to anticipate to ensure a smooth transition?

A COMPULSORY VISIT TO EORI-SIREN

Until now, the EORI number assigned in France was based on the SIRET, which meant that a company could have several EORI numbers if it had several establishments. From 2025, customs identification of companies will be simplified with the EORI-SIREN, a unique identifier linked to the company’s SIREN.

Key stages in this transition:

Since November 2023: possibility of requesting an EORI-SIREN on the Customs portal.
March 18, 2024: automatic deletion of EORI-SIRET numbers of closed establishments.
During 2025: transition period allowing companies to adapt their processes and obtain their EORI-SIREN before it becomes mandatory.
January 1, 2026: only the EORI-SIREN is valid for customs formalities.

Note that AEO (Authorized Economic Operator) certified operators do not need to do anything, as their EORI is already attached to their SIREN.

On the other hand, companies trading with the UK and Ireland need to be extra vigilant. Customs formalities with these countries require a valid EORI-SIREN number, for both exports and imports.

DELTA I/E: THE NEW ONLINE CUSTOMS DECLARATION PLATFORM

Another major development in 2025 is the introduction of DELTA I/E, which will gradually replace the DELTA G and X systems currently used for imports and exports. The objectives of DELTA I/E are to dematerialize and simplify customs procedures, reinforce interconnection with tax bases and other European customs systems, and improve the fluidity and traceability of commercial exchanges.

SUMMARY OF ACTIONS TO BE TAKEN NOW

The year 2025 is therefore a transitional phase, and from 2026 onwards, only EORI-SIREN numbers will be accepted, and DELTA I/E will become the standard for all customs operations.
Companies located in France (including DROM COM), importing or exporting goods and services outside the EU must therefore now :

Check whether they already have an EORI-SIREN.
Apply via the Customs portal if necessary.
Anticipate the changes linked to DELTA I/E to avoid any disruption to their trade. For companies, the transition to DELTA I (import) must be completed by May 31, 2025, while the deadline for switching to DELTA E (export) is currently December 14, 2025. The Delta I/E customs clearance system, whose import section now operates primarily with the EORI SIREN number but, failing that, with the EORI-SIRET number, will continue to be valid during this December 2025 transition period. In fact, no EORI-SIRET number will be deactivated before the end of the IT transition period, except in the case of a number attached to an inactive establishment.
