What is a seller sku on amazon?

A Seller SKU (Stock Keeping Unit) on Amazon is a unique identifier used by third-party sellers to track and manage their inventory. It is an alphanumeric code assigned to each product a seller offers on the Amazon platform.

Key points about a Seller SKU on Amazon:

1. Uniqueness: Each product offered by a seller on Amazon must have a unique Seller SKU. This helps sellers maintain control and visibility over their inventory.

2. Customization: Sellers have the flexibility to create their own Seller SKU, allowing them to organize and categorize their products based on their own inventory management system.

3. Differentiation: Seller SKUs can be different from Amazon's standard product identifier, such as UPC or EAN. This allows sellers to distinguish their version of a product from others in the marketplace.

4. Inventory Management: Seller SKUs enable sellers to keep track of their stock levels, monitor sales performance, and replenish inventory efficiently.

5. Product Variation: When a seller offers variations of a product (e.g., different sizes or colors), they can assign unique Seller SKUs to each variation to manage them separately.

6. Multi-Channel Selling: Seller SKUs are not limited to Amazon's platform. If sellers list their products on other online marketplaces or their own website, they can use the same Seller SKU across multiple channels to streamline inventory management.

7. Internal Reference: Besides helping sellers manage inventory, Seller SKUs can also serve as internal references for various business operations, such as customer service, order management, and accounting.

It is worth noting that Amazon has its own Product ASIN (Amazon Standard Identification Number) to uniquely identify products in its catalog. While Seller SKUs and ASINs can be linked, they are not the same thing.
