One product, three SKUs, scattered stock and split ad data — how duplicate SKUs happen on Amazon, what they break, and how to see one product again.

Duplicate SKUs happen because Amazon identifies the product by ASIN but your account tracks offers by SKU — relist the same product with a new SKU name and you've created an alias, not a new product. The units, sales history, and ad data split across aliases, making one healthy product look like several weak ones. Amazon has no "merge SKUs" button; the fix is consolidating your view and future stock, not deleting history.

## FAQ

Q: Can Amazon merge my duplicate SKUs into one?
A: No — SKUs are permanent identifiers in your account. You can consolidate stock into one going forward and let the others empty out, but the merge happens in your management view, not in Amazon's ledger.

Q: Should I delete the old duplicate listings?
A: Not while any FBA units remain behind them (deletion strands the units), and generally not at all — closed SKUs keep history attached. Zero them out and stop using them instead.

Q: Do duplicate SKUs hurt my ranking?
A: Ranking is per-ASIN, so aliases don't split rank. They split YOUR data — stock views, ad reporting, profitability — which leads to worse decisions, which eventually hurts rank the honest way.
