After trying to update images via a flatfile, 3 of my products have become stranded with listing error shown on the fix stranded page. I was advised to delete the sku and relist, but it has not worked. Now it just says create listing, but it does not work and I get this error:
The product data you are submitting has changed such that your product or SKU will be associated with a different product in the Amazon catalog using this ASIN if this data is processed. Before we can process this product data, you must first remove any active offers for this product from Amazon.
Tried via flatfile and get this error:
You are attempting to change an identity attribute for this SKU. To proceed, please delete this SKU and recreate the SKU with the appropriate identity attribute. For more information and detailed instructions, see: 23191
It has passed 24hrs and I am still unable to relist the 3 products. I have lots of inventory at FBA and I am losing sales.
Please does anyone have any solutions to this? Do I need to wait longer?
This usually happens when Amazon locks an identity attribute like ASIN, UPC, or brand during a flatfile update, and once that conflict is triggered, simply deleting and recreating the SKU often won’t clear it immediately.
The standard fix is to fully delete the SKU and ASIN from your account, wait at least 24–48 hours for the system to purge the backend connection, and then re-upload the product with a fresh SKU through a flatfile or manual creation. If it still doesn’t work after that timeframe, you’ll need to open a case with Seller Support and explicitly request a “catalog team override” because only they can reset the listing identity attributes when inventory is stranded in FBA.
To speed this up, provide them with your flatfile, the error code (23191), and proof that you already have stock in Amazon’s warehouse, which should push them to escalate it. In the meantime, do not keep trying to re-upload the same SKU repeatedly, as that can extend the lockout period.
You mentioned needing to delete the entire ASIN. Do you mean all of the SKUs? (We have both FBM and FBA SKUs.)
If we delete them, will the ASIN and its data/reviews still remain on Amazon?
What do you mean by a “fresh SKU”? The only way I can fix the stranded inventory is by reactivating the same SKU that is linked to the FNSKU of the existing inventory.
This issue was caused by accidentally uploading my UK flat file to the US marketplace. The products have the same SKU in both marketplaces, but obviously different ASINs.
When you get the 23191 error it means Amazon sees a conflict in the “identity attributes” (ASIN, UPC, Brand, etc.) for that SKU, and once that happens the SKU itself is effectively corrupted and can’t be reused until the backend clears.
Deleting the SKU means deleting both your FBM and FBA offers for that ASIN in that marketplace, but the ASIN itself and its reviews remain intact in Amazon’s catalog because those are tied to the catalog entry, not your offer.
A “fresh SKU” simply means creating a brand-new seller SKU (different text string than before) so Amazon generates a new FNSKU label, and then mapping that fresh SKU back to your existing FBA inventory through a stranded inventory fix request with Seller Support.
Since your stock is already sitting at Amazon under the old FNSKU, you’ll need to open a case with the FBA team, give them the shipment IDs and old FNSKUs, and ask them to relink the units to your newly created SKU.
If you keep trying to re-activate the old SKU, the system will keep blocking it, so the workaround is to abandon that SKU and have support remap the stranded inventory. Accidentally uploading the UK flat file to the US created the identity clash, and only Amazon’s catalog or FBA team can override it, so deleting the old offers, waiting 24–48 hours, and then uploading a new SKU with correct ASIN mapping is the way forward.
I have tried the delete and relist and it just doesn’t work as I get the same error saying I can’t reuse the SKU.
I have created a new SKU, and I’ve tried to request FBA team to remap the old FNSKU to the new FNSKU - but they say it’s not possible? Can it definitely be done? Then I’ll keep requesting it until someone does it.
Any idea if we need to delete the SKU’s in other marketplaces outside of US/Canada/Mexico - as we use the same SKU’s globally. As far as I am aware, there should not be any connections between SKU’s in other marketplaces.
