Auto SKU Generator takes the hassle out of creating SKUs for your WooCommerce products. Instead of manually typing a SKU for every product, this plugin automatically generates structured, unique SKUs based on your product’s category and ID.
How It Works
When you create or save a WooCommerce product without a SKU, Auto SKU Generator automatically assigns one using a consistent format:
[Prefix][Product ID][Suffix]
- The prefix is derived from the product’s category ID (zero-padded to 3 digits) or a custom prefix you define per category.
- The product ID portion is zero-padded to fill the remaining SKU length.
- A trailing digit is appended to ensure uniqueness in case of collisions.
Features
- Automatic SKU assignment — Products saved without a SKU get one automatically.
- Two prefix modes — Use the category ID as a prefix, or define your own custom prefix for each category.
- Configurable SKU length — Set your preferred total SKU length between 8 and 20 characters.
- Live SKU preview — A suggested SKU appears below the SKU field on the product edit screen, updating in real time as you change categories.
- Click-to-insert — Click the suggested SKU to instantly populate the SKU field.
- Collision handling — If a generated SKU already exists, the plugin automatically tries alternative suffixes.
- Settings page — Configure everything from Products > Auto SKU Generator in your WordPress admin.
- Clean uninstall — All plugin data is removed when you delete the plugin.
Use Cases
- Online stores with large product catalogs that need consistent SKU formatting.
- Shops where multiple team members add products and you want standardized SKUs.
- Stores migrating from another platform that need to establish a new SKU system.
- Any WooCommerce store that wants to save time on manual SKU entry.
