Licensing & Pre-Sale Questions
- Do I need a license for each website?
Yes. Each license works on one website only. If you run multiple stores, you’ll need separate licenses for each domain. Your license key won’t activate on different domains. - What happens if my license expires?
Your plugin keeps working, but you lose access to updates and support. Keys you’ve already created stay active. Renew anytime to get updates and priority support back. - Can I move my license to a new domain?
Yes. Deactivate the license from your old site first, then activate it on the new domain. You can do this from your PluginEver account or contact support for help. - Will this work with my existing WooCommerce setup?
The plugin works with WooCommerce 7+ and WordPress 6+. It plays nice with most themes and payment gateways like Stripe, PayPal, and Square. Check the compatibility list if you’re using specialized plugins. - What’s the difference between Free and Pro versions?
Basic handles simple key generation and email delivery. Pro adds SMS delivery, variable product support, bulk import/export, backorder management, and advanced generator rules. - Can I try it before buying?
Yes. We have a demo you can test from here. WC Serial Numbers Demo

Use Cases
Game Keys & Account Sellers
Sell Steam keys, Origin codes, or gaming accounts with complete automation. Import bulk keys from suppliers via CSV, then let customers receive them instantly after payment. Use SMS delivery to cut down on “where’s my key?” support tickets and keep gamers happy.
Digital Download Shops
Sell WordPress themes, plugins, or digital assets with instant key delivery. Start with basic email delivery, then upgrade to SMS for faster customer satisfaction and fewer support tickets.
Event Organizers
Generate unique entry codes for conferences, workshops, or concerts. Basic email works for small events, but SMS delivery (Pro) ensures attendees get codes instantly, even in poor email reception areas.
Software & App Developers
Distribute activation codes for desktop apps, mobile software, or SaaS platforms. Begin with manual key entry, then scale with generator rules (Pro) to handle hundreds of daily sales automatically.
Digital Agency Client Work
Manage licenses across multiple client projects. Start small with manual assignment, then leverage bulk import/export (Pro) to handle enterprise clients with thousands of keys.
E-Learning & Course Creators
Sell access codes for online courses, tutorials, or coaching programs. Email delivery gets you started, while variable products (Pro) let you sell different course tiers with unique access levels.
Physical Product Authentication
Add serial numbers for warranty claims, product registration, or anti-counterfeiting. Basic tracking works initially, but Pro’s advanced reporting helps scale as your product line grows.
