Pros
- ✓Shopify Best Practices Built-In

Cons
- ✗Manual Entry Required
This generator doesn’t integrate directly with Shopify. You’ll need to manually copy SKUs to your product listings or import via CSV.
- ✗No Auto-Generation for Existing Products
Best for new products. For existing inventory without SKUs, you’ll need to generate each one individually or use a Shopify app.
- ✗No Duplicate Detection
The tool generates codes based on your input but doesn’t check against your existing Shopify inventory for duplicates.
- ✗Basic Barcode Support
Generates SKU codes only. For UPC/EAN barcodes, you’ll need a dedicated barcode generator or Shopify app.

What is a SKU and Why Does It Matter for Shopify Stores?
A SKU (Stock Keeping Unit) is a unique alphanumeric code that identifies each product in your inventory. Unlike barcodes (UPC/EAN), which are universal, SKUs are created by you and customized to fit your business needs.
For Shopify stores, SKUs are essential for: Better Inventory Tracking: Know exactly which products you have in stock and where they’re located. SKUs help you track inventory across multiple locations and sales channels.
Accurate Sales Reporting: Shopify’s analytics and reports work best when every product has a unique SKU. Track sales by product, variant, and category with precision.
Faster Order Fulfillment: Staff can quickly find and pack the right products when each item has a clear, readable identifier. This reduces picking errors and speeds up shipping.
Easier Returns & Exchanges: Handle customer returns efficiently by looking up the exact product variant using its SKU code.
Multi-Channel Selling: If you sell on Amazon, eBay, or other marketplaces, consistent SKUs help you manage inventory across all platforms without confusion.
According to Shopify’s guidelines, a good SKU should be 8-16 characters, use a mix of letters and numbers, and avoid confusing characters like 0/O and 1/I. Our SKU generator follows these best practices automatically.

Q: How do I create a SKU number for Shopify?
A: Use our free Shopify SKU generator: enter your product category, name, and attributes (color, size, etc.), then click generate. Copy the SKU and paste it into your Shopify product’s “SKU” field under Inventory. You can also export to CSV for bulk import.
Q: Does Shopify require SKU numbers?
A: No, Shopify doesn’t require SKUs, but they’re highly recommended. SKUs improve inventory tracking, sales reporting, order fulfillment accuracy, and multi-channel selling. Stores with SKUs are easier to manage and scale.
Q: What’s the difference between SKU and barcode in Shopify?
A: SKUs are internal codes you create for your own inventory tracking. Barcodes (UPC/EAN) are universal product identifiers used for retail scanning. Shopify has separate fields for both—you can use one or both on each product.
Q: Can I use the same SKU for different products?
A: No, each product and variant must have a unique SKU. Duplicate SKUs cause inventory tracking errors, reporting issues, and problems with third-party integrations. Shopify will warn you if duplicates are detected.
