What is a SKU number?

SKU code stands for "Stock Keeping Unit". This is a unique identifier used in inventory management to identify and track individual products or different types of goods.

SKU codes can include information such as product type, size, color, style, and any other attributes needed to differentiate the product. Using SKU codes helps organize and manage inventory more effectively, making it easier to search, check inventory, and manage different products.

2. Instructions for creating the simplest SKU code

Step 1: Determine the SKU number format

First, choose the SKU number format that suits your business plans and needs. Consider what information to contain, such as product attributes (size, color, material), or any other relevant identifiers. Normally, warehouse management units will create SKU codes in different formats such as:

  • Sequential numbers (e.g. 0001, 0002)
  • Date-based numbers (e.g. YYMMDD)
  • Hierarchical number (e.g. category-subcategory number)

Choose a format that is easy to understand, consistent, and flexible for future business growth.​

Step 2: Select information for SKU number

Based on the format, choose what information to include in the SKU number. For example: With clothing, size and color can be added; with electronics, this may include brand, model, and specifications. Information elements typically include:

  • Product type
  • Brand
  • Size
  • Color
  • Material
  • Style
  • Seasonality

Choose relevant and meaningful information to help businesses easily find and classify products when needed.

Step 3: Assign unique code to each product

Assign unique codes to each product based on the format and information selected. Ensure uniqueness and no overlap with current or future codes. Use serial numbers or a combination of numbers and letters to create uniqueness. Consider using a consistent pattern or logic to easily identify product attributes or categories from SKU numbers.

Step 4: Check the SKU number

After generating SKU codes, check for accuracy and efficiency. Ensure SKU numbers are unique and information is accurate. Test by applying to actual products and inventory management. This helps detect potential issues and make improvements before implementing the SKU system across the warehouse.

Creating SKU codes is extremely simple and easy to understand for many people.
