WooCommerce being an eCommerce platform you will have to search for products in different ways and one of them is using SKU.

To equip SKU search in a WooCommerce site, you will need to append ‘SKU:’ at the start of your product search followed by the product ID in your products panel of WooCommerce.

This search will return you the product whose product ID you have specified.
