Stock Keeping Unit SKU Generator

Frequently asked questions

What is an SKU?

A SKU (Stock Keeping Unit) is a unique identifier used by businesses to track inventory. It typically contains alphanumeric characters that represent details such as product type, size, color, or other distinguishing features. Having clear, consistent SKUs helps ensure accurate inventory management and streamlined order fulfillment.

Why do I need an SKU for my products?

SKUs allow you to quickly identify specific products in your inventory, making it easier to manage stock levels, track sales performance, and avoid mix-ups. They're especially helpful if you sell variations of the same product (e.g., different sizes or colors) across multiple sales channels like Etsy, Shopify, or your own website.

How many characters should an SKU have?

There's no strict rule, but most sellers prefer 8-12 characters for readability and consistency. Longer SKUs can capture more product information but may be harder to manage. The Craftybase SKU Generator can help you strike the right balance between detail and simplicity.

Can I change my SKUs after I generate them?

Yes. You're free to edit your SKUs at any time, although it's best to finalize a consistent SKU format early to avoid confusion. If you sell on multiple platforms, remember to update the SKUs everywhere to maintain consistency and accurate product tracking.

Are SKUs the same as barcodes or UPCs?

No. While both SKUs and barcodes/UPCs uniquely identify items, SKUs are internal and typically created by the business. Barcodes or UPCs are standardized codes recognized by scanners and are often issued by external organizations. Craftybase’s SKU Generator focuses on helping you create internal SKUs for inventory management.
