Hi @owlnest
In WooCommerce, the SKU and Product ID are two different entities. SKU is a unique identifier that you can assign to each product for inventory tracking, while the Product ID is a unique number automatically assigned by WooCommerce when a product is created.
While they serve different purposes, you can certainly make your SKU and Product ID the same if you wish, but this is not done automatically within WooCommerce. You would need to manually assign the SKU to match the Product ID for each product.
I hope this clarifies your concern. If you have any other questions, feel free to ask.
