Dealing with Conflicting Values When Adding Products on Amazon

When listing products on Amazon, you might encounter the error: “The value specified conflicts with the value for ASIN in the Amazon catalog.” This typically occurs when either:

You’ve already listed a product with the same UPC.
Another seller has improperly used your unique barcode.

Amazon’s system doesn’t clear old listings, which can lead to “tombstoned” ASINs tied to old, incorrect GTINs. Unfortunately, Amazon doesn’t purge these listings, causing complications.
