From the developer

Vollstart's own description of Serial Codes Generator and Validator with WooCommerce Suppor..., lightly tidied.

Manage your Serial Codes the easy way.

Video

Allows you to manage codes (serial numbers) for your digital licensed products and physical products. Your user enters the code on your page and checks if the code is valid.

Optional for you is the included support for Woocommerce products and WooCommerce PDF Invoices – generate your WooCommerce serial directly with a purchase.

“Check out the overview video”

If you use woocommerce, you can uset the option to auto generate a serial code for each sold product!

WooCommerce is NOT required, but just additional supported by our plugin if needed by you.

Shop: With Serial Code Generator your will be able to sell license keys and products with a serial number or activation key. The plugin can create the code on the fly or use unused serials from your code list for each sold item.

Validation of serials: You customer can validate a serial on your page. The code generator gives you a flexible pattern to generate codes upfront. You can also import your existing codes.

Sell software & deliver files with a serial code: Attach downloadable files (your software, PDFs, e-books, licenses …) to a code list and every serial in that list unlocks the download. Files are kept in a protected folder that cannot be reached by a public URL and are only served through a code-gated download link that re-validates the serial on every request — the code itself is the key, no login required. Large files support resume/partial downloads (HTTP Range), so download managers and interrupted transfers just continue. A global emergency-off switch lets you stop all downloads at once. With Premium you can also limit how often each code may download a file, log every download, require a WordPress login (guests are sent to the login form and back), and deliver the download links right inside the WooCommerce order, confirmation email and PDF invoice.

Build your own stolen serial database: Support your customer and yourself to protect stolen products to be sold to others. Mark reported stolen products as stolen and let others check the serials.

How can you setup the serial code generator?
You can enter your codes within the WP admin area in the serial code section (a new menu point in the wordpress amdin area).
You can add your own codes manually using the serial code generator or import existing codes.
The codes can also be generated by the plugin. The serial code generator can create a bulk of serials or numbers as codes.
And you are also able to add your own codes by just entering them to the generated codes below the serial code generator.
If needed you can assign the codes to a list. The list (code list) helps you to organize the codes. The code list can be assigned to a WooCommerce product, if you want to add a serial code to each sold product.
Create one or more code lists to use the WooCommerce functionality.

How the serial code generator works
You define your look and feel for your codes. The generated codes will be unique. After you are satisfied with the generated codes, you can start the code adding step.
The code adding step will check if the code is unique on the server before adding it.
If the code (serial number/ticket number) exists already on the server, it will not be added.

The generator provides a lot of features:

  • Code prefix – you can enter a fixed prefix to each code
  • Length of code
  • Only letters
  • Uppercase, Lowercase or both
  • Exclusion of letters that are easy to missread (i,l,o,q,p)
  • Delimiter possible: [None, -, :, SPACE] – you decide after how many letters within the code
  • CVV code generation (only numbers)
