SKU
SKU (Stock Keeping Unit) is an internal identifier used by sellers to track, manage, and organize products and variations within their own inventory systems.
What is a SKU?
A SKU, or Stock Keeping Unit, is a unique code created by the seller to identify and manage products internally. Unlike ASINs, SKUs are customizable and help sellers track inventory, variations, and fulfillment performance.
Why SKUs Are Important
- Helps organize inventory across multiple marketplaces
- Tracks product variations such as size or color
- Simplifies fulfillment and accounting processes
- Reduces inventory and fulfillment errors
- Essential for internal reporting and analysis
SKU vs ASIN
While ASINs are assigned by Amazon and are public, SKUs are created by sellers and are only visible within Seller Central. Multiple sellers can have different SKUs for the same ASIN.
