Serial Numbers & License Keys for WooCommerce

Serial Numbers & License Keys for WooCommerce allows you to sell secret keys, license codes, and gift cards directly through WooCommerce.
The plugin supports both Simple and Variable Products, enabling different keys or rules to be assigned per variation.

Serial keys are automatically assigned when an order is completed and are displayed securely on the customer’s order page and in order emails.

The plugin operates entirely within your WordPress installation and does not transmit customer or license data to external servers.

Features

• Support for Simple and Variable WooCommerce products
• Automatic assignment of serial keys on order completion
• Bulk generation of keys using custom patterns (e.g. KEY-####-####)
• CSV import and export for easy migration
• Secure storage using a dedicated database table
• Clear overview of available and used keys

Optional Extensions

Optional extensions may be available separately to add additional automation and management features.
