Your IDU is not on Amazon.
7 reasons it happens and how to fix each one.

Before retrying or contacting Amazon, do this one check. Go to syderep.ademe.fr and search for your IDU. If it appears, copy the legal name exactly as displayed. If it does not appear, you are not actually registered yet from Amazon’s perspective, every IDU diagnosis starts here.

No identifier at all yet, and Amazon is asking for one? This page is for an IDU you already hold. Start with how to get a French IDU for Amazon France instead, or, for other platforms, your marketplace asks for a French EPR number.

Amazon verifies your IDU by querying SYDEREP, the public registry maintained by ADEME. The platform does not call the eco-organism, does not check internal documents, and does not look at your filings. If SYDEREP does not return a match, Amazon rejects. The 7 reasons below all reduce to a SYDEREP-side problem or an Amazon-side data entry problem.

1. Is the IDU published on SYDEREP yet?

The most common cause. Your eco-organism (Citeo, Refashion, Ecosystem…) confirmed registration by email, sometimes even gave you the IDU number, but ADEME has not yet made it visible on the public SYDEREP teleservice.

Fix: Wait. Search SYDEREP weekly until the IDU appears. Do not retry uploading on Amazon during the wait, repeated failed attempts can flag your account.

2. Does the legal name on SYDEREP match Amazon Seller Central?

Your Amazon legal entity reads “Acme Limited”. SYDEREP reads “ACME LIMITED HK” (the eco-organism added a country suffix). The string comparison fails. Same root cause as on Cdiscount.

Fix: Update your Amazon Seller Central business name to match SYDEREP exactly. Changing SYDEREP is slower (requires re-filing with the eco-organism). It is almost always faster to edit the Amazon side.

3. Does the listing also need a WEEE or battery IDU?

Amazon parses your listing taxonomy and demands one IDU per applicable stream. A Bluetooth speaker triggers packaging (the box) + WEEE (the electronics) + batteries (the embedded battery). Three IDUs, three filings. Sellers regularly upload one IDU thinking it covers everything.

Fix: Audit your catalog against the 19 EPR streams. File a separate dossier with each relevant eco-organism. The representative mandate covers any number of streams under one umbrella.

4. You pasted the IDU into the wrong field in Seller Central

Amazon has stream-specific fields under Compliance → Extended Producer Responsibility. You must paste the IDU into the field matching that stream, pasting a Citeo packaging IDU into the WEEE field returns “invalid”. Amazon checks not only that the IDU exists but that it covers the right stream.

Fix: In Seller Central, go to Settings → Compliance → EPR France. Confirm each IDU is in the correct stream row before saving. The IDU prefix (the first 4 characters) typically signals the stream, your representative can map them for you.

5. Amazon has not refreshed its check yet

After you submit a valid IDU, Amazon caches its SYDEREP lookup and refreshes it on its own schedule. Your listings will not re-activate instantly even on a successful submission.

Fix: Allow a few business days. If listings are still down, open a case in Seller Central referencing the IDU and ASKING for cache refresh. Templates and timelines in our Amazon suspension recovery guide.

6. The IDU was revoked

IDUs are not permanent. The eco-organism can revoke your IDU if you miss a declaration, fail to pay eco-contributions, or breach your contract. Once SYDEREP reflects the revocation, Amazon returns “IDU not found” on a number it accepted six months ago.

Fix: Contact your eco-organism (or your representative) to understand which obligation triggered the revocation, then settle it. Note: this is a known pain point, so set up reminders for each declaration. Most streams are declared once a year; Ecomaison, Valdelia, Ecominéro and Ecosystem electrical equipment more often.

7. You operate multiple Amazon seller accounts on the same IDU

Each legal entity gets one IDU per stream. If you operate two separate Amazon Seller Central accounts under two different legal entities, you need two registrations, one IDU per entity per stream. Reusing the same IDU across entities will pass on one account and fail on the other.

Fix: File a separate registration for each legal entity. The representative can group them under one mandate but the eco-organism dossiers are separate.

How do I find which cause applies?

Run the seven checks below in order. The first one that fails is your cause.

If three or more of these come back unclear, a representative can read your SYDEREP record and tell you which item is breaking the verification. See our pricing or request a written quote with the rejection screenshot.
