Introduction

In the retail industry, the terms SKU and UPC are often used interchangeably, leading to confusion among business owners. However, understanding the distinctions between these two codes is crucial for effective inventory management and supply chain tracking. SKUs, or Stock Keeping Units, are unique alphanumeric codes assigned to products by a company for internal use. On the other hand, UPCs, or Universal Product Codes, are standardized 12-digit numeric codes licensed by manufacturers from organizations like GS1 for external use in the global supply chain.

What is a SKU?

A SKU, or Stock Keeping Unit, is a unique identifier assigned to a product by a company for internal use. It serves as a way to track and manage inventory, optimize stock levels, and streamline operations. Each SKU represents a specific product variant, allowing retailers to differentiate between different sizes, colors, models, or other attributes.

– Internal Use and Inventory Management

Unlike UPCs, SKUs are not intended for external use. They are designed to be used internally within a company’s inventory management system. With SKUs, businesses can easily track the number of units sold, monitor stock levels, and analyze sales trends. By assigning a unique SKU to each product variant, retailers can efficiently manage their inventory and ensure accurate stock replenishment.

– Alphanumeric Code Format

SKUs are alphanumeric codes that typically consist of a combination of letters and numbers. The format and length of SKUs may vary depending on the company’s internal system and requirements. While there are no specific rules for creating SKUs, businesses often incorporate relevant information into the code, such as product attributes, manufacturer details, or category information.

– Benefits of SKUs

Using SKUs in inventory management offers several benefits for retailers:

1. Efficient Tracking: SKUs enable retailers to track and monitor individual products, providing insights into sales performance, stock levels, and demand patterns.

Unlike SKUs, which are for internal use, UPCs are designed for external use across various retail environments and supply chains. They enable accurate product tracking, inventory management, and seamless transactions between manufacturers, distributors, retailers, and consumers. UPCs ensure interoperability and consistency in product identification and barcode scanning systems.

– 12-Digit Numeric Code Format

UPCs are always 12-digit numeric codes, without any letters or special characters. The code is divided into three sections: the first six digits represent the manufacturer or brand, the following five digits represent the specific product, and the last digit is a check digit used for error detection. This standardized format ensures that each UPC is unique and globally recognized.

– Licensing and Standardization

To obtain UPCs, manufacturers must purchase and license them from organizations like GS1, a nonprofit entity that maintains global standards for business and supply chain operations. GS1 ensures that each UPC is a unique identifier for a specific product and guarantees interoperability between different organizations. Licensing UPCs from GS1 involves a fee, which varies depending on factors such as the number of UPCs required and the company’s annual revenue.

SKU vs UPC: Key Differences

While both SKUs and UPCs are codes used to identify and track products, they have several key differences. Understanding these differences is essential for effectively implementing inventory management systems and supply chain tracking. Let’s explore the main distinctions between SKUs and UPCs:

– Internal vs External Use

The most fundamental difference between SKUs and UPCs is their intended use. SKUs are primarily for internal use within a company’s inventory management system. They help track and manage inventory, optimize stock levels, and streamline operations. On the other hand, UPCs are used externally, allowing for accurate product identification, supply chain tracking, and seamless transactions between different organizations.

– Unique Identification

SKUs and UPCs differ in terms of their uniqueness. SKUs are unique within an organization, meaning that two companies may have identical SKUs assigned to different products without any conflict. This uniqueness is crucial for internal inventory management and differentiation between product variants. In contrast, UPCs are universally unique, ensuring that each product has a distinct identification code that remains consistent throughout the supply chain.

– Code Format

Another key difference lies in the format of the codes. SKUs are alphanumeric, consisting of a combination of letters and numbers. This allows businesses to incorporate relevant information and attributes into the code structure. SKUs can vary in length, typically ranging from 8 to 12 characters. In contrast, UPCs are strictly numeric, consisting of 12 digits. This standardized format ensures consistency and facilitates accurate scanning and recognition across different barcode systems.

– Attributes and Information

SKUs and UPCs also differ in terms of the information they represent. SKUs often encode various attributes of a product, such as size, color, style, or manufacturer details. These attributes can be reflected in the alphanumeric code, providing further insights and categorization within the company’s inventory management system. UPCs, on the other hand, represent broader product identification and do not typically encode specific attributes. They focus on providing a unique identifier for each product that remains consistent throughout the supply chain.
