Quick summary: An EORI number plays an important role in identifying businesses involved in EU customs activities. Discover how EORI requirements relate to EUDR economic operators, customs declarations, Due Diligence Statements, and the information businesses need to prepare for compliant EU trade.
An EORI (Economic Operators Registration and Identification) number for economic operators is the EU customs identifier used to identify economic operators and certain other persons for customs purposes. The European Commission states that an EORI number is mandatory for customs clearance in the EU, including import, export and transit. It is therefore important for businesses that combine EUDR compliance with EU customs processes.
As businesses prepare for EUDR implementation, much of the focus is on due diligence, geolocation, deforestation checks, legality evidence and Due Diligence Statements (DDS). But there is another important identifier that connects an economic operator with EU customs: the EORI number.
The EORI number is a unique identifier assigned by an EU Member State customs authority. It allows customs authorities to identify an economic operator consistently across EU customs operations. An operator can have only one valid EORI number at a time, and the number is used in communications with EU customs authorities where a customs identifier is required.
The European Commission states that an EORI number consists of the two-letter country code of the issuing EU country followed by an identifier of up to 15 alphanumeric characters. EORI numbers do not have a normal expiry date, although they can be invalidated in certain circumstances.
The EORI number is not an EUDR due-diligence requirement by itself, and it does not replace a DDS. Its importance comes from the connection between customs identity and the EUDR Information System.
Under the current EUDR Regulation, for operators placing relevant products under the customs procedure ‘release for free circulation’ or ‘export’, the EORI number established under the Union Customs Code must be included in the operator’s registration profile in the EUDR Information System.
This creates an important operational connection: the company’s customs identity, EUDR registration and DDS workflow need to be aligned. For technology teams, EORI should therefore be treated as important organisation master data rather than as an isolated customs number.

The European Commission identifies several categories of persons who may need an EORI number:

| Identifier | Purpose | EUDR relevance |
|---|---|---|
| EORI number | Identifies the economic operator for EU customs purposes. | Included in relevant EUDR Information System registration profiles for operators using release for free circulation or export. |
| DDS reference number | Identifies a submitted Due Diligence Statement. | Connects the relevant product or shipment to the submitted due diligence statement. |
| DDS verification number | Supports verification of a DDS. | Used for verification where applicable; it is not the EORI number. |
| Simplified Declaration identifier | Identifies a simplified declaration. | Relevant where the simplified declaration regime applies. |
A common question is whether a non-EU supplier automatically needs an EORI number simply because it supplies an EUDR-relevant product to an EU customer. The requirement depends on its customs activities.
The European Commission states that non-EU economic operators may need an EORI when they lodge customs declarations, entry summary declarations, exit summary declarations, declarations for temporary storage, or act as a carrier.
Therefore, an EU importer should distinguish between a supplier’s commercial role and its role in the EU customs process. An EORI requirement should be assessed based on the actual customs activity rather than assumed solely because the supplier is outside the EU.
These identifiers have different purposes. The EORI identifies the economic operator for customs purposes. A DDS reference number identifies a submitted Due Diligence Statement. A DDS verification number is associated with verification of the statement and is not the same thing as an EORI number. A simplified declaration has its own declaration identifier.
A practical rule is: EORI identifies the business; the DDS reference identifies the due diligence statement. Businesses should keep these fields separate in their compliance systems.
Learn how to manage DDS reference numbers, declaration identifiers, verification details and downstream traceability without losing track of the compliance trail.

For businesses managing EUDR through software, EORI should be part of organisation and compliance master data. A robust workflow should connect the EORI with the legal entity, EUDR role, customs activity, products, shipments and DDS records.
Technology should be able to maintain EORI against the correct legal entity, validate that it is present where required, keep EORI separate from DDS references and verification numbers, connect product and shipment information with the relevant EUDR record, maintain an audit trail when registration data changes, and support role-based workflows for operators, downstream operators, traders and authorised representatives.
TraceX EUDR Solutions helps businesses connect EUDR compliance data with the operational supply chain. EORI can be managed as part of organisation and customs master data, while supplier information, production locations, geolocation, legality evidence, risk assessment, traceability and DDS workflows remain connected in the same compliance process.
This matters because EUDR compliance does not stop when the DDS is submitted. Businesses also need to connect the right product and shipment to the right compliance record and, where applicable, provide the required EUDR information through the customs process. A connected technology workflow reduces the risk of treating customs identifiers, EUDR references and supplier evidence as separate spreadsheets.
EUDR compliance involves more than collecting supplier data and submitting a DDS. Businesses need to connect economic operators, products, geolocation, due diligence evidence, DDS references and customs information in one traceable workflow.
No. The EORI identifies the economic operator for customs purposes. The DDS reference identifies a submitted Due Diligence Statement.
No. EORI is a customs identification number. It does not prove that a product is deforestation-free, legally produced or covered by a valid due diligence process.
Not automatically. The requirement depends on the supplier’s customs activities and establishment status.
For operators placing relevant products under release for free circulation or export, the EUDR Regulation requires the EORI number to be included in the operator’s Information System registration profile.
The Commission states that, at any point in time, a person can have only one valid EORI number. Specific rules apply to non-EU operators with multiple permanent establishments in the EU.
The European Commission provides an EORI validation service for checking whether an EORI number or registered person is valid.
