Amazon GB - Follow-up needed: Amazon EAN & SKU correction

Dear WakeCommerce Team, I need your support on a high-priority Amazon catalog issue that requires immediate follow-up on Amazon GB (I already handled Amazon BE). Context of the issue - I initially opened Amazon cases requesting EAN and SKU changes for several ASINs. - Amazon already changed the SKUs, but EAN changes are still pending. - After internal alignment, we confirmed that the new EANs and SKUs represent new product IDs, meaning they must be created as new ASINs, not updated on existing ones. - Because of this, I asked Amazon to stop the EAN changes and to revert the SKUs back to the original ones (provided in the spreadsheet I'm sharing with you), but this has not yet been fully corrected. - Currently, the incorrect SKU setup is blocking the creation of the new ASINs, due to external product ID conflicts. What we need you to do Please open a new case on Amazon GB (except Amazon BE) with the following request: - Ask Amazon to update the existing ASINs with the OLD EANs and OLD SKUs, exactly as shown in the spreadsheet I will share with you. - Clearly state that the EANs and SKUs in the spreadsheet are the correct and final identifiers for those ASINs. - Explain that this correction is required because the new products include some updates and therefore need to be listed under new ASINs (these represent the new versions of the older ASINs), allowing us to create them separately with the new EAN and SKU references without conflicts. Important - This is a high-priority issue. - Amazon needs to fully correct both EANs and SKUs according to the spreadsheet. - Please monitor the cases closely and follow up until Amazon confirms the correction. I will share with you the spreadsheet containing only the old EANs and SKUs to be used as reference in each case. Thank you in advance for your support and close follow-up on this. Kind regards, Gabriela
