We’re facing an ongoing issue with 7 of our parent-child listings that were originally created in 2022 using UPC codes purchased from a third-party website. In December 2023, we received error code 8572, instructing us to repurchase UPCs for these ASINs directly from GS1.
To comply, we purchased new UPC codes from GS1 and applied them to the physical products stored in our warehouse. However, Amazon is not allowing us to update the listings with the new GS1 UPCs. When we attempt to do so, the system throws an error stating that the UPC in the catalog does not match the one we're trying to add — which is precisely the issue we’re trying to fix.
Despite months of back-and-forth with Seller Support (mostly receiving copy-paste responses), we were finally informed that the old UPCs had been de-associated and that we could assign the new ones after 72 hours. However, even after waiting and trying again multiple times over the past few weeks, the same error continues to appear.
We have tried everything — using flat file uploads, deleting and relisting the ASINs — but the issue remains unresolved. We've opened multiple cases, yet the support team seems unable to understand the core of the problem. We're now incurring storage fees on unsellable FBA inventory, and losing potential sales since the listings can't be updated or sold under a single variation family.
Can anyone here help resolve this issue or advise how we can get in touch with Amazon's technical support team directly? We really need a resolution at this point.
Thanks
