Re: I need help with public id and merging my accounts

The Public ID is also referred to as Origin ID or more common the Origin username.

If you do not have a Public ID yet and have played on console only, you might get prompted to set up one before you can proceed.

You can also log on to the Origin website with your existing Origin account using your email address to set up your Public ID there. You can change that at a later time as well.
