SKU Number: What is the SKU Number, Examples and How to Create One
6 min read

A Stock Keeping Unit (SKU) is a unique alphanumeric code assigned to a product by a retailer to help track inventory, manage stock, and sales processes. Each SKU represents specific product details, such as size, color, brand, and category, making it easier for businesses to identify and manage their products efficiently.
For example, a retailer selling shoes might assign the SKU code SH123-BLK-8 to a black shoe in size 8. This ensures that every product variation is easily distinguishable in inventory systems.
Why Are SKU Numbers Important?
SKU numbers play a great role in the operations of any business. They simplify inventory management by providing a clear system for tracking stock levels, which helps prevent overstocking or running out of popular items. Employees can quickly locate, organize, and identify products in warehouses or retail spaces using SKUs, which improves productivity and speeds up order fulfillment.
For customers, using SKU numbers translates to faster service and better satisfaction as their orders are processed more accurately. Businesses also benefit from improved sales analysis since SKUs make it easy to identify which products are selling well and which are underperforming. Without SKU numbers, managing products can become disorganized, leading to inefficiencies and potential financial losses.
How to Use The SKU Numbers
1. Inventory Management
SKU numbers are a powerful tool for managing inventory. They allow businesses to track products with precision, ensuring that stock levels are consistently monitored. By scanning the SKU number of an item, employees can quickly determine how many units are available, where they are located in the warehouse, and when it's time to reorder.
2. Order Fulfillment
When processing orders, SKU numbers help in picking and packing products accurately and quickly. Whether an order is placed online or in-store, employees can use the SKU number to locate the exact product variation, such as size or color. In warehouses, systems that scan SKUs ensure the right items are shipped, improving order accuracy and reducing the chances of returns or exchanges due to mistakes.
3. Sales Tracking
SKU numbers can provide valuable insights into a business’s sales performance. By tracking SKUs, businesses can identify which products are selling well and which ones are not. This data helps in decision-making, such as determining which items to promote, discontinue, or reorder.
4. Integration with POS and E-commerce Systems
SKU numbers are integrated into point-of-sale (POS) systems and e-commerce platforms. When a customer makes a purchase, the system automatically records the SKU, updating inventory counts in real-time. This reduces the risk of errors in stock reporting, ensuring that businesses always have an accurate understanding of their available inventory.
5. Managing Product Variations
SKU numbers are useful when businesses sell products with multiple variations, such as clothing with different sizes and colors or electronics with varying features. By creating a unique SKU for each variation, businesses can easily track specific items and make informed decisions about their stock. For instance, a t-shirt might have one SKU for size small and another for size medium, making it clear which variation is being purchased or sold. Also, SKU numbers make it easier to update product listings on online stores by linking the same product across multiple platforms.
6. Automating Replenishment Orders
Using SKU numbers with inventory management software enables automated stock replenishment. When the stock of a particular SKU reaches a preset threshold, the system can trigger a reorder from suppliers. This helps maintain inventory levels without manual intervention, saving time and ensuring that products are available for customers.
7. Product Returns and Exchanges
SKU numbers simplify the process of handling returns and exchanges. By associating each returned product with its SKU, businesses can quickly identify the product, verify its condition, and process the return or exchange. This ensures that returns are handled smoothly, contributing to a better customer experience and minimizing confusion for both staff and customers.
How to Create the SKU Number of a Product
Creating SKU numbers requires a structured and logical approach to ensure they are effective for both tracking and inventory organization. Start by choosing a format that incorporates key product attributes, such as the product category, unique identifier, and specific attributes like color or size.
For example, a t-shirt might have the SKU TSH123-BLU-M, where "TSH" represents the category (t-shirt), "123" is a unique identifier, and "BLU-M" denotes a blue, medium-sized shirt.
Category Code: Product type (e.g., SHO for shoes).
Product ID: A unique identifier for each product.
Attributes: Color, size, or other variations (e.g., BLK for black, L for large).
Example: SHO123-BLK-L.
