Hi, I’d like to know if there’s a way to permanently delete a listing from my Seller Central account as well as from the Amazon catalogue. I’m planning to relist the item with improved variation options and would like to reuse the existing barcodes.

Not that I'm aware of. You can delete the SKU from seller central - but the ASIN itself on amazon won't disappear.

But what do you mean by improved variation options but reuse the existing barcodes?

• If the product is the same - you would use the same barcode and would just need to update the listing
• If the product is different, then you'd need a different barcode

A little more info about what you are doing would be useful.
