Stock Keeping Unit (SKU) is a unique identifier used in inventory management to distinguish individual items or products within a company’s inventory. SKUs play a crucial role in streamlining operations, optimizing inventory, and facilitating efficient order fulfillment. By assigning a unique SKU to each product, businesses can track and manage inventory levels accurately, prevent stockouts, and enhance the overall efficiency of their supply chain. In this article, we will delve into the concept of SKUs, their significance, and how they contribute to effective inventory management.
What is a Stock Keeping Unit (SKU)?
A Stock Keeping Unit (SKU) is a distinct alphanumeric code or number assigned to each individual product or item in a company’s inventory. Stock keeping unit are unique to each product variant and represent specific attributes such as size, color, style, or packaging type. They provide a standardized way to identify and track inventory items, making it easier for businesses to manage their stock levels and monitor sales performance.
Stock Keeping Unit (SKUs) vs. Universal Product Codes (UPCs)
Stock Keeping Unit (SKUs) and Universal Product Codes (UPCs) are both used in inventory management and product identification, but they serve different purposes and have distinct characteristics. Let’s explore the differences between SKUs and UPCs:
Purpose and Usage
- SKUs: Stock Keeping Unit are internal identifiers used by businesses to track and manage their inventory. SKUs are unique codes assigned to individual product variants, allowing businesses to differentiate products based on attributes like size, color, style, or packaging type. SKUs are primarily used for inventory management, order fulfillment, and internal tracking purposes within a company’s supply chain.
- UPCs: Universal Product Codes are standardized barcodes used for scanning and product identification at the point of sale. UPCs are issued by the GS1 organization and are unique to each product regardless of its variant or attributes. UPCs are primarily used for retail and point-of-sale purposes to facilitate efficient and accurate product scanning during checkout.
Uniqueness
- SKUs: SKUs are unique only within the company’s inventory system. Different companies may use the same SKU for different products. SKUs are not standardized across industries or businesses.
- UPCs: UPCs are globally unique for each product. Every UPC corresponds to a specific product regardless of the manufacturer or retailer. This uniqueness allows UPCs to be recognized universally across different retail locations and supply chains.
Product Variants
- SKUs: SKUs are specifically designed to manage different product variants within a company’s inventory. Each variant of a product, such as different sizes or colors, may have its own SKU.
- UPCs: UPCs represent the core product itself, regardless of its attributes or variants. All product variants of the same item share the same UPC.
Generation
- SKUs: Businesses have flexibility in creating their own SKU formats and can design them to suit their internal needs and product categorization.
- UPCs: UPCs are generated and managed by GS1, a global standards organization. Companies must obtain UPCs from GS1, ensuring the uniqueness and standardization of the barcode.
Use in Inventory Management
- SKUs: SKUs play a central role in inventory management for internal tracking, restocking, and order fulfillment within a company’s supply chain.
- UPCs: UPCs are not typically used for internal inventory management. Instead, they are scanned at retail points of sale to access product information, price, and facilitate seamless checkout processes.
Integration with E-commerce
- SKUs: SKUs are commonly used in e-commerce platforms to manage product listings, track inventory levels, and synchronize data across multiple sales channels.
- UPCs: UPCs are used in e-commerce as well, but their primary role is to ensure accurate product identification and facilitate scanning during online and offline purchases.
In summary, while both SKUs and UPCs are essential in inventory management and product identification, they serve different purposes and cater to different stages of the supply chain and retail process. SKUs are internal identifiers used for inventory management, while UPCs are standardized barcodes used primarily for product scanning and identification at retail points of sale. Both SKUs and UPCs are critical components of efficient supply chain and retail operations.

Key Components of an Stock Keeping Unit
A Stock Keeping Unit (SKU) is a unique identifier assigned to each individual product or item in a company’s inventory. The SKU comprises several key components that help distinguish and classify the products accurately. The key components of an SKU include:
Product Identifier
The product identifier is the fundamental element of an SKU, and it serves as the primary distinguishing factor for each item in the inventory. It is usually a combination of letters and/or numbers that uniquely represent a specific product. This identifier helps employees and inventory management systems quickly identify and differentiate one product from another. It is essential to ensure that the product identifier is unique and does not overlap with other products in the inventory.
For example, in a retail store that sells different types of electronics, the product identifier for a smartphone could be “SMRT” to represent smartphones in general.
Attribute Identifier
The attribute identifier is a crucial component of the SKU that represents specific attributes or variations of the product. These attributes can include characteristics such as size, color, flavor, style, or packaging type. Including attribute identifiers in the SKU allows businesses to track and manage different variants of the same product efficiently.
For example, consider a clothing retailer selling T-shirts. The attribute identifier in the SKU could include codes like “S” for small, “M” for medium, “L” for large, “BLU” for blue color, “RED” for red color, “V-NECK” for V-neck style, and “ROUND-NECK” for round-neck style.
Brand or Manufacturer Identifier
Some SKUs include a code or abbreviation that identifies the brand or manufacturer of the product. This component is particularly useful for retailers carrying products from multiple brands or manufacturers. Including the brand or manufacturer identifier in the SKU helps with easy identification and categorization of products.
For example, if a retail store carries products from multiple electronics brands, they may include a brand identifier like “SAMS” for Samsung, “APPL” for Apple, or “SONY” for Sony.
Vendor Identifier (Optional)
In some cases, especially in large-scale or multinational businesses, SKUs may include a vendor identifier. This identifier indicates the supplier or source of the product. Including a vendor identifier can be beneficial for businesses with complex supply chains and multiple suppliers.
For example, if a company sources products from different manufacturers or vendors, they may include a vendor identifier like “VND-A” for Vendor A and “VND-B” for Vendor B.
By combining these key components, businesses can create unique SKUs for each product variant in their inventory. These SKUs play a vital role in inventory management, order fulfillment, and supply chain optimization. With accurate and well-structured SKUs, businesses can efficiently track and manage inventory levels, prevent stockouts, analyze sales performance, and deliver a seamless customer experience.
