User Registration Invite Codes Addon is a WordPress plugin that enhances the registration process on your website by introducing an invite-only system. Here are the key features and functionalities of this addon:

1. Invite-Only Registration: With this addon, you can restrict user registration on your website to only those individuals who possess a valid invitation code. Users who do not have an invitation code will be denied registration.
2. Creation of Invitation Codes: You have the ability to create single or multiple invitation codes. These codes can be used by individuals to gain access to the registration process on your site.
3. Expiration Dates: For added security and control, you can set expiration dates for the invitation codes. After the specified date, the code will no longer be valid for registration.
4. Usage Limits: You can define how many times each invitation code can be used. Once an invitation code has been used the specified number of times, it will no longer grant access to registration.
5. User Role Assignment: You can specify which user roles individuals will be assigned to when they register using an invitation code. This allows you to categorize users based on their registration method.
6. Bulk Code Generation: The addon provides the option to generate a large number of invitation codes in bulk. This can be particularly useful if you need to create multiple codes for different purposes.
7. Integration with Registration Form: Adding the invitation field to your registration form is made simple. You can easily drag and drop the field into your form, and it will be seamlessly integrated into the registration process.

In summary, the User Registration Invite Codes Addon is a valuable tool for WordPress website owners who want to implement an invitation-only registration system. This feature can be useful for various purposes, such as creating a sense of exclusivity, controlling the number of registrations, or managing user roles. By setting expiration dates and usage limits, you have complete control over the registration process and can tailor it to your specific needs.
