2 of 5 measures had too little evidence to score. They are left out of the total rather than counted as zero — otherwise a plugin would be marked down for being small rather than for being poorly kept.Measured 2026-08-01 from the WordPress.org plugin registry.
Ratings

No one has rated this plugin on WordPress.org yet. That is a statement about the ratings page, not about the plugin — plenty of well-kept plugins never collect them.

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
  • Compatible with standard WooCommerce order emails

Optional Extensions

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

  • Automatic order completion for key-based products
  • Low stock notifications for serial keys
  • Advanced key lifecycle handling (refunds and cancellations)
  • Integration with third-party invoice and PDF plugins

The free plugin functions independently and does not require the extension.

Does this plugin work with Variable Products?

Yes. Serial keys and settings can be managed separately for each product variation.

Where are serial keys stored?

Keys are stored in a custom database table created using the WordPress database prefix for performance and scalability.

Is any data sent to external servers?

No. All data is stored locally within your WordPress installation.

Does the plugin clean up data on uninstall?

Yes. Plugin options and database tables are removed when the plugin is uninstalled.
