What Does SKU Stand For? A Complete Guide for Retail and Beyond
Updated on July 31, 2025, by Xcitium

If you’ve ever worked in retail, logistics, or eCommerce, you’ve likely encountered the term SKU. But what does SKU stand for, and why is it essential to every industry dealing with inventory?
SKU stands for Stock Keeping Unit. It’s a unique alphanumeric code assigned to a product for inventory tracking, management, and sales analysis. SKUs help businesses monitor stock levels, identify trends, and streamline operations. Whether you’re an IT manager setting up inventory systems or a cybersecurity expert integrating product tagging with asset tracking, SKUs play a crucial role.
🔍 What Does SKU Stand For?
SKU is short for Stock Keeping Unit, a term used to identify a specific product or item for sale. It typically consists of:
- Letters and numbers
- Encoded product attributes like size, color, style
- A format unique to the company
For example: SKU-TSH-RED-L-2024 might represent a red T-shirt, size large, in 2024’s inventory catalog.
Note: SKUs are created and managed by companies—unlike UPCs (Universal Product Codes), which are standardized.
📦 SKU Number Example: How It Looks in Real Life
Here’s a simple breakdown of a SKU number example for an electronics retailer:
ELX-IPH13-128GB-BLK
Explanation:
- ELX = Electronics
- IPH13 = iPhone 13
- 128GB = Storage size
- BLK = Black color
This SKU helps identify the exact product variant in seconds.
🛒 SKU Meaning in Retail
In retail, SKUs are indispensable. They help with:
- Inventory control: Track stock levels in real-time
- Sales reporting: Analyze which products are top-performers
- Order management: Prevent out-of-stock issues
- Shelf replenishment: Keep popular items well-stocked
Retail Use Cases
- Point-of-Sale systems scan SKUs to manage pricing
- Online stores use SKUs to differentiate product listings
- Warehouses use SKUs for product location mapping
📌 SKU vs UPC: What’s the Difference?
Feature | SKU | UPC |
Meaning | Stock Keeping Unit | Universal Product Code |
Format | Alphanumeric (customizable) | Numeric (12 digits) |
Usage | Internal (company-specific) | External (universal) |
Example | SHOE-NIKE-BLUE-10 | 012345678912 |
Who Assigns It | Retailer or company | GS1 (Global Standards Org) |
Think of SKUs as in-house labels, while UPCs are global identifiers.
