How Amazon SKUs are written
SKUs make it easy for e-commerce brands to identify items.
There are multiple SKUs when a product has multiple attributes such as different colors and sizes.
For example, if a dress comes in 3 colors, black, white, and grey, and each color comes in different sizes, S, M, L, and XL, then there are 12 SKUs for this dress.
SKU1: black, s
SKU2: black, m
SKU3: black, l
SKU4: black, xl

Amazon SKU Role
- Manage Inventory: SKUs allow merchants to quickly see how much and where inventory is in stock and which products need to be restocked by scanning barcodes or QR codes.
- Analyzing Sales: SKUs allow merchants to collect scan data to see which products are selling well and which are selling poorly, as well as information on price, time, and location of sales.
- Promote Purchase: SKUs allow merchants to recommend similar or related products to customers based on the characteristics of the product, increasing customer purchase intent and satisfaction.
- Provide service: SKU allows merchants to provide customers with better services, such as returns, exchanges, repairs, etc., based on the information of the product.
Rules for writing Amazon SKUs
Regarding the rules of writing SKU, Amazon does not have strict requirements, sellers can fill in the SKU column by sellers themselves when they publish their products.
If you don’t fill it in, Amazon will automatically generate a SKU code assigned to you, which will make it hard to recognize.
So in order to facilitate the future management of the product, it is better for the seller to write the SKU according to their own management habits or product characteristics.
Amazon SKU Label Size
Amazon SKU label size must be less than 75mm x 75mm
