If your home page is not your Admin Dashboard, click on the drop down box at the bottom of the screen next to “Viewing Dashboard For” to view a list of organizations that you are an administrator for. Click on the name of your organization you’d like to access.

From your Admin Dashboard, click the "Events" tab. From there, click the "Edit" button within the event you’re looking to access.

Within your Event editor, click on the "Event Fundraising" tab on the left, and scroll down to locate the section labeled "Registration Codes"

Next to the registration code will be a pencil icon, or an "X", click the "X" to have a prompt appear. The prompt that appears will confirm that you want to delete the code, click "OK".

If your code is already in use, then you will not be able to delete it. You may want to instead archive it. Click the pencil icon to bring up the registration code editor. From the editor, you can check the box, "Archive this code to prevent it from being used."

Note: Once a registration code has been deleted there is no way to recover it.
