Quick summary: EUDR Reference Number Management helps link DDS records to products, shipments, suppliers, evidence, and downstream traceability for audit-ready compliance.
A practical guide to tracking, connecting and retaining EUDR submission records
EUDR Reference Number management an operational traceability task not simply an administrative activity. An EUDR Due Diligence Statement (DDS) does not end when the submission is accepted. The reference number generated by the EUDR Information System becomes an important link between the submitted due-diligence record and the relevant product moving through the supply chain.
The European Commission states that once a DDS has been accepted in the Information System, the operator may place the product on the market or export it, and the operator must pass the DDS number to its direct downstream buyer for traceability.
The real value of an EUDR Reference Number is not the number itself. It is the ability to connect that number to the product, shipment, supplier, due-diligence evidence and downstream transaction it represents.
The bigger takeaway: An EUDR reference number isn’t just a submission ID, it should be the gateway to the complete compliance record behind that submission.
An EUDR Reference Number is the identifier generated by the EUDR Information System for an accepted Due Diligence Statement. It provides a reference to the submitted statement and supports traceability between upstream due diligence and relevant products moving downstream.
The European Commission’s Information System allows operators and authorised representatives to create, submit and manage DDSs and simplified declarations. The system assigns the relevant reference number or declaration identifier to the submitted record.
It is important to distinguish a DDS reference number from a simplified declaration identifier. Micro and small primary operators using the simplified declaration process receive a declaration identifier rather than a standard DDS reference number.
Filing a DDS is more than entering information into the EUDR Information System. Your submission depends on having accurate product data, supplier information, geolocation, risk assessment and supporting evidence ready beforehand.
In a complex supply chain, one company may handle many suppliers, commodities, batches, products and shipments. A single DDS can potentially cover multiple shipments or batches, while one customs declaration can also contain multiple DDS reference numbers or declaration identifiers, subject to the applicable requirements.
This creates a record-management challenge.
Without a structured approach, teams can end up maintaining reference numbers in spreadsheets, emails, ERP notes and shipment folders making reconciliation difficult.
A useful model is:
Supplier → Plot → Commodity → Purchase → Batch → Product → Shipment → DDS → EUDR Reference Number → Downstream Record
The reference number should sit within this chain rather than outside it.
That makes it possible to move in both directions: from a shipment back to the DDS and supporting evidence, or from a DDS forward to the products and transactions it supports.

The first step is to create a controlled register of submitted DDSs and their identifiers.
The exact fields should reflect the organisation’s compliance process and applicable EUDR requirements.
A reference number has limited operational value if it is stored without product context.
Businesses should establish a relationship between the EUDR Reference Number and the relevant product, commodity and quantity. This is particularly important when a company manages multiple similar products or shipments from different sourcing origins.
The EUDR Information System itself supports viewing and managing DDSs through a dashboard, while bulk management is also available through an API.
The next level of traceability is connecting the DDS to the physical movement of goods.
For example:
DDS → Reference Number → Shipment → Batch → Finished Product
This allows logistics, customs and compliance teams to work from the same traceability relationship.
For imports, the DDS reference number or simplified declaration identifier must be available to customs authorities through the customs declaration. The Commission states that due diligence and submission must occur before the customs declaration is lodged for the relevant product.
EUDR traceability requires more than knowing who your supplier is. Businesses need to connect origin, farm geolocation, suppliers, transactions, batches and products to build a defensible compliance trail.
Businesses should not automatically assume that every shipment requires a unique DDS.
The Commission states that where a DDS covers multiple shipments or batches, the same DDS reference number can be referred to in several customs declarations, provided the legal requirements of the EUDR are respected. Multiple reference numbers or declaration identifiers can also be included in one customs declaration.
This makes relationship management more important than simple one-to-one numbering.
DDS consolidation can help simplify compliance when multiple transactions or product flows need to be managed across the same supply chain. Learn how to organise DDS records, connect submissions with underlying traceability data, and maintain a clear compliance trail.
Reference numbers also have a role beyond the organisation that submitted the DDS.
Operators must pass the DDS number generated by the Information System to their direct downstream buyers for traceability.
Under the current Commission guidance, the first downstream operator or trader must collect and keep DDS reference numbers or simplified declaration identifiers for at least five years, but does not need to pass those numbers or identifiers to its own buyers. citeturn0search0
This makes it important to distinguish the different roles in the supply chain rather than assuming every company has the same reference-number obligation.
Downstream operators face specific responsibilities when placing or making relevant products available on the EU market. Understanding how supplier information, Due Diligence Statements, traceability records and risk information flow through your supply chain is critical.
A reference number should lead back to the evidence supporting the due-diligence decision.
That can include:
The Commission states that operators must maintain their due-diligence system and retain documents related to due diligence for five years from the date the product is placed on the EU market or exported.
A good EUDR Reference Number management process should distinguish between different submission states.
The EUDR Information System provides a dashboard for viewing and managing submissions, with status updates as records are processed.
Keeping internal workflow status aligned with the official submission status can reduce confusion when several teams are working on the same transaction.
Spreadsheets can be useful for an initial register, but they become harder to control as transaction volumes grow.
Common problems include:
A digital traceability layer can reduce these risks by making the reference number part of the product and transaction record.
TraceX EUDR Solutions can help organisations connect EUDR submission records with the broader supply-chain data behind them.
The objective is not to create another reference-number spreadsheet. It is to make the EUDR Reference Number part of a connected traceability record.
The biggest mistake businesses can make is treating the EUDR Reference Number as a standalone compliance field.
A number without context does not tell your team which product it supports, where the commodity originated, which supplier provided it or what evidence was used to reach the due-diligence conclusion.
The better approach is to treat the reference number as a digital link:
SOURCE → PLOT → COMMODITY → BATCH → PRODUCT → SHIPMENT → DDS → REFERENCE NUMBER
This turns reference-number management into a traceability capability rather than an administrative exercise.
EUDR Reference Number management is becoming an important part of supply-chain traceability. The reference number connects the formal due-diligence submission with the products, shipments and downstream relationships that depend on it.
The strongest approach is therefore not to maintain a list of numbers, but to build a connected record around every number linking it to the product, source, batch, shipment, evidence and relevant downstream transaction.
It is the identifier generated by the EUDR Information System for an accepted Due Diligence Statement. It supports traceability between the submitted statement and relevant products in the supply chain.
The EUDR Information System generates the reference number for a DDS submitted through the system. For products requiring a DDS, due diligence and submission must be completed before the relevant product is placed on the EU market or exported.
The operator receives the reference number and must pass it to the direct downstream buyer for traceability. The first downstream operator or trader must collect and retain applicable DDS reference numbers or simplified declaration identifiers for at least five years.
Yes, where a DDS covers multiple shipments or batches, the same reference number can be used in several customs declarations provided the EUDR’s legal requirements are met.
Operators must keep documents related to due diligence for five years from the date the relevant product is placed on the EU market or exported. First downstream operators or traders must also keep applicable DDS reference numbers or simplified declaration identifiers for at least five years
A DDS reference number identifies a submitted Due Diligence Statement. A simplified declaration identifier is generated for the simplified declaration process available to eligible micro and small primary operators.
