What Is a SKU?
SKU is an acronym for Stock Keeping Unit and it is simply a distinctive code given internally to each product by retailers. SKUs are alphanumeric, usually consisting of eight to twelve numbers and they are used to keep track of the level of inventory of a business.
SKUs are peculiar to each product as they help show the important information of a product such as the department, style, type, price, size, color, gender, and others. These details are usually arranged in order of priority and significance.
However, a SKU is not universal as it is generated by individual retailers for their brand. There is no definite SKU architecture, so each brand has to come up with their own unique way of generating SKUs.
