The French EPR IDU Number Explained: A Complete Guide for Foreign Companies

If you sell into France from outside the European Union, sooner or later a marketplace, a customs officer, or an inspection authority will ask you for your IDU. If you do not have one, your listings come down, your shipment is held, or your file goes to an enforcement queue. This article is a working reference on what the IDU is, where it comes from, where to display it, and what to do when it changes.

The IDU is not optional and it is not a marketplace artefact. It is a French government identifier, issued by ADEME under Article L. 541-10-13 of the Code de l'environnement, and it travels with you across providers, marketplaces, and time.

What IDU stands for and what it actually is

IDU stands for Identifiant Unique — Unique Identifier in English. It is a producer identifier issued by ADEME, the French environment agency, through a teleservice called SYDEREP. Every producer of products falling under a French EPR stream must have one IDU per stream they operate in.

Concretely, an IDU is a 9-character code. The first two characters identify the stream (for example FR012345678 for household packaging, with a stream-specific prefix). The remaining characters are a sequence number unique to your registration in that stream. The IDU is permanent for the life of your registration. It does not expire annually. It is revoked only if the underlying registration is terminated (by you, by your eco-organism for serious breach, or by ADEME for fraud).

The IDU is attached to the producer, not to the authorized representative. If you change French representatives, your IDU stays with you. If you terminate your representation altogether (because you have established an EU subsidiary, for example), your IDU continues to belong to you and your replacement registration uses it.

Where the IDU comes from

The legal source is Article L. 541-10-13 of the Code de l'environnement, introduced by the AGEC law of 10 February 2020. It establishes a national producer registry, managed by ADEME, and requires every entity placing products on the French market under an EPR stream to be registered in it.

The operational path runs as follows:

1. You sign a mandate with a French authorized representative (or, if you are EU-incorporated, you skip this step)
2. Your representative submits your membership application to the relevant eco-organism (Citeo for household packaging, Ecosystem for WEEE, Refashion for textile, and so on)
3. The eco-organism processes the application, typically within 1 to 5 business days, and issues a membership certificate (attestation d'adhésion)
4. The eco-organism transmits your registration data to ADEME
5. ADEME issues your IDU through SYDEREP within 2 to 3 weeks of the eco-organism membership

In total, a clean process delivers your IDU within 2 to 3 weeks from mandate signature. The first 48 to 72 hours after mandate produces the eco-organism membership certificate, which is usually sufficient to unlock a suspended Amazon France or ManoMano account pending the formal IDU.

One IDU per stream, not one IDU per company

This is the most common confusion among non-EU sellers, and it costs people money.

The French system assigns IDUs at the stream level, not at the company level. A non-EU seller of electronic devices with retail packaging needs at least three IDUs:

• One for WEEE (issued by Ecosystem or Ecologic)
• One for batteries (issued by Corepile or Screlec)
• One for household packaging (issued by Citeo, Léko, or Adelphe)

Each IDU has its own renewal cycle, its own declaration deadline, and its own marketplace registration field. Sellers who register only for one stream, thinking it covers everything, regularly face partial suspensions: their packaging IDU is good, but they still get blocked because their WEEE IDU is missing.

Map your products carefully against the ten French EPR streams before any registration. Most non-EU e-commerce sellers end up needing two to four IDUs.

Where to display the IDU

Five places matter:

Amazon Seller Central. Under Account Health → Compliance, there is a section for "Extended Producer Responsibility" (EPR). For each French EPR stream, you upload your IDU and the corresponding eco-organism. Amazon France verifies the IDU automatically on submission and periodically thereafter. Missing or invalid IDU triggers listing suspension.

ManoMano, Cdiscount, Fnac Marketplace, TikTok Shop France. Each has its own compliance portal but expects the same artefact: IDU per stream, with the eco-organism named. The verification logic is broadly similar to Amazon's.

Your invoices and commercial documents. Article L. 541-10-13 requires producers to make their IDU available. In practice, including it as a footnote on invoices and order confirmations is sufficient. For larger B2B clients, the IDU often appears in supplier compliance documentation.

Your terms of sale (CGV). Add a clause referencing your French EPR compliance, listing your IDU(s) and the eco-organism(s) you adhere to. This protects you against customer challenges and demonstrates due diligence in marketplace audits.

The product page or product packaging itself. For certain streams (notably household packaging), French regulation requires the Triman logo and Info-tri sorting instructions on the packaging itself. The IDU does not generally need to appear on the product, but the Triman compliance does.

What you do not need: posting the IDU on your homepage or in a public registry. The IDU is administrative, not marketing.

What happens when something changes

Several events trigger IDU-related work. None of them are catastrophic if you handle them in sequence.

You change French representative. Your IDU stays. The old representative withdraws their mandate notification with the eco-organism. The new representative re-registers as your authorized representative against your existing IDU. The eco-organism membership continues; only the contact-of-record changes. Marketplaces continue to verify against the same IDU.

You switch eco-organism within a stream. For example, you move from Citeo to Léko for household packaging. This is permitted; both are agreed eco-organisms in the same stream. The process is: terminate the Citeo membership, sign with Léko, and Léko notifies ADEME. The IDU may be reissued or kept depending on ADEME's process at the time; either way, you must update marketplaces with the new eco-organism and possibly new IDU.

You add a new product category. If your new product triggers a new stream (for example, you start selling battery-powered toys when you previously sold non-battery toys), you need to register in the additional stream. This produces an additional IDU. Add it to marketplaces.

You lose marketplace certification despite a valid IDU. This happens when the marketplace's verification system desyncs from ADEME's data, or when your eco-organism membership is in a transitional state. Provide the eco-organism membership certificate as a backup, and ask your representative to escalate with the eco-organism if needed.

Your registration is terminated by the eco-organism. This is rare and serious. It usually indicates a major declaration breach, unpaid contributions, or fraud. Termination triggers IDU revocation. Marketplaces detect the revocation within days and suspend listings. Recovery requires re-application from scratch and is significantly slower than initial registration.

What marketplaces actually check

Marketplace verification of IDUs runs in three layers, in roughly this order:

Layer 1: format check. Is the IDU well-formed (correct length, correct prefix for the stated stream)? This is automated and instant.

Layer 2: registry cross-check. Is the IDU present in ADEME's public registry, or in the eco-organism's data feed to the marketplace? Most marketplaces have direct or indirect access to ADEME's data, usually updated daily or weekly.

Layer 3: stream match. Does the IDU correspond to the stream(s) of the products you are listing? A WEEE IDU does not unlock packaging-only listings. A battery IDU does not unlock furniture listings. This check is increasingly automated but can be manual for complex multi-stream portfolios.

When a verification fails, the marketplace sends a compliance notice via Seller Central or its equivalent. You typically have 7 to 14 days to remediate before listings are removed. Once listings are removed, recovery is harder than prevention; respond to the initial notice promptly.

How to obtain your IDU as a non-EU seller

The fast path:

1. Designate an authorized representative. A French entity with eco-organism relationships. The mandate is signed under Articles 1984 and 1998 of the Code civil. Post-EcoDDS regime: no subrogation.

2. Eco-organism membership. Your representative submits your application. Membership certificate arrives within 1 to 5 business days.

3. ADEME registration. The eco-organism transmits to ADEME. ADEME issues IDU via SYDEREP within 2 to 3 weeks.

4. Marketplace update. As soon as you have the IDU (or the membership certificate as an interim), update Seller Central and equivalent on every French marketplace where you sell.

The slow path (going alone from outside France):

1. Establish a French postal address that can receive registered mail
2. Open a French bank account, or arrange a SEPA-capable European account
3. Translate your corporate documents (statutes, registration certificate) into French
4. Submit eco-organism applications directly, often with multiple rounds of clarification
5. Register on SYDEREP yourself, in French

Timeline for the slow path: typically 6 to 12 weeks. This is why most non-EU sellers, particularly under marketplace suspension pressure, take the representative path.

Frequently asked questions

Is the IDU public information? The producer registry maintained by ADEME under Article L. 541-10-13 is partially public. Your name and IDU per stream are visible. Marketplaces and inspection authorities use this for verification.

Can two companies share one IDU? No. The IDU is tied to one legal entity, identified by its registration documents. Two related companies under the same group must each have their own IDU per stream.

What if I have multiple legal entities selling into France? Each entity that independently places products on the French market needs its own IDU per applicable stream. This often surprises non-EU sellers with multi-entity structures (for example, a Chinese parent company plus a Hong Kong sales subsidiary both shipping to France).

Does the IDU need to appear on the product itself? No. The IDU is an administrative identifier, not a product marking. The product marking obligations (Triman logo, Info-tri sorting instructions) are separate from the IDU.

Is the IDU number transferable in case of company acquisition? The IDU travels with the legal entity. If you acquire another company that has its own IDU, the acquired entity keeps its IDU. If you merge entities, the surviving entity takes one IDU and the absorbed entity's IDU is terminated; declarations from prior years remain attached to the historical registrations.
