What Is Seller Sku On Amazon

Are you looking to sell your products on Amazon? If so, understanding the concept of Seller SKU is crucial for effective inventory management and streamlined operations.

In this blog post, we will delve into the world of Seller SKU on Amazon and explore its significance in the e-commerce landscape.

A Seller SKU, or Stock Keeping Unit, is a unique identifier assigned to each product listing created by a seller on Amazon. It differentiates your product from others and aids in tracking and managing your inventory efficiently. Unlike the Amazon Standard Identification Number (ASIN), which is assigned by Amazon, the Seller SKU is generated by the seller.

By creating a Seller SKU, you can easily track your products, monitor stock levels, and fulfill orders accurately. It also allows you to create variations of a product and manage them separately.

In this blog post, we will guide you through the process of creating a Seller SKU on Amazon and highlight the benefits it offers for your business.

Different Between ASIN and SKU

When it comes to selling products on Amazon, two important identifiers come into play: ASIN (Amazon Standard Identification Number) and Seller SKU (Stock Keeping Unit). While both serve the purpose of identifying products, there are key differences between them.

ASIN (Amazon Standard Identification Number)

  • Assigned by Amazon: ASINs are unique identifiers assigned by Amazon to each product listed on their platform.
  • Universal Identification: ASINs are universal and apply to all sellers offering the same product. This means that multiple sellers listing the same product will have the same ASIN.
  • Product Details: ASINs are tied to specific product details, such as the brand, model, and edition. This ensures consistency across listings for the same product.

Seller SKU (Stock Keeping Unit)

  • Assigned by Sellers: Seller SKUs are unique identifiers created by individual sellers for their product listings on Amazon.
  • Seller-Specific: Each seller can assign their own Seller SKU to a product, allowing them to differentiate their listings and track inventory according to their own system.
  • Variations and Management: Seller SKUs enable sellers to create variations of a product, such as different sizes or colors, and manage them separately.

Importance of Seller SKU on Amazon

Seller SKU plays a crucial role in managing inventory and optimizing operations on Amazon. Here are some key reasons why Seller SKU is important:

  • Efficient Inventory Management: By assigning unique Seller SKUs to each product, sellers can easily track and manage their inventory levels. This helps in avoiding stockouts, ensuring timely replenishment, and optimizing the overall supply chain.
  • Accurate Order Fulfillment: Seller SKU enables sellers to accurately pick and pack the right products for each order. It eliminates confusion and minimizes the chances of shipping incorrect items to customers, leading to improved customer satisfaction.
  • Simplified Product Identification: With a well-structured Seller SKU system, sellers can quickly identify and locate specific products within their inventory. This saves time and effort, especially when dealing with a large number of SKUs.
  • Streamlined Sales Tracking: Seller SKU allows sellers to track the performance of individual products. By analyzing sales data associated with each SKU, sellers can make informed decisions regarding pricing, promotions, and inventory restocking.
