SKU Naming Conventions & Best Practices
A Stock Keeping Unit (SKU) is a unique alphanumeric code that identifies each product or variant in your inventory. Well-structured SKUs make warehouse operations faster, reporting more accurate, and multichannel selling less error-prone.
Anatomy of a Good SKU
Effective SKUs encode the most important product differentiators in a short, readable format. The typical structure is: [Category]-[Attribute]-[Attribute]-[Sequence]. Each segment uses 2–3 character codes that are consistent across your entire catalog.
Key Rules
- Keep it 8–16 characters — Long enough to be descriptive, short enough to scan quickly on pick lists and labels.
- Use uppercase letters and numbers only — Avoid lowercase, special characters (except hyphens as separators), and ambiguous pairs like O/0 or I/1.
- Never start with zero — Some systems strip leading zeros, which can corrupt your SKU.
- Be consistent — Document your convention and enforce it company-wide. Every new product should follow the same pattern.
- Never reuse retired SKUs — This avoids confusion in historical reports, returns, and warranty tracking.
