Your users can enter a code in the registration forms you selected in the Code Settings page. The field is named Registration Code.

The forms

• WordPress registration form: the field is added to the form. It is optional unless you made the code mandatory.
• WooCommerce registration form (My Account page): the field is added to the form, with a star when the code is mandatory.
• WooCommerce checkout: the field is added to the account fields of the form, for visitors who are not logged in. It is required when the code is mandatory.
• Your own form: the shortcode form of the Registration Form page has its own code field. See Build a Registration Form.

What happens when a user submits a code

• The code is valid: the account is created and the user gets the role of the code.
• The code is unknown: the form shows Invalid Registration Code.
• The code is draft, inactive, expired or exhausted: the form shows This code isn’t valid anymore.
• The field is empty and the code is mandatory: the form shows Registration Code is mandatory.
• The field is empty and the code is not mandatory: the registration goes on as usual, with the default role of the form.
