SKU (Stock Keeping Unit) — A unique code assigned to a specific product variant, used to track it separately from other products.
What Is a SKU?
Each variant of a product — a different size or color, for example — usually gets its own SKU. That lets a store track which specific version is actually selling, not just the product as a whole.
Why SKUs Matter for Dropshippers
Even without holding inventory, organized SKUs matter once a catalog grows past a handful of products. Without them, it becomes hard to see which specific variant is worth promoting more.
FAQ
Does a dropshipping store need to assign its own SKUs?
Many store platforms generate SKUs automatically, but assigning clear, organized SKUs matters especially once a catalog grows past a handful of products.
Is a SKU the same as a product ID?
They’re related but not always identical — a SKU is usually a human-readable code a business assigns, while a product ID may be a platform-generated identifier behind the scenes.
Why do variants need separate SKUs?
Separate SKUs per variant, like size or color, make it possible to see which specific version of a product is actually selling, rather than just the product as a whole.
