How to recover an old iCloud account without the original Apple Account?

Typically an Apple ID is an email address you have used. If you are currently using a mobile device that is logged into your account, go to Settings and tap your name at the top.

Look in the Passwords application (or Keychain), and in a browser's security settings if you use it to automatically sign into Apple when using a browser.

Fixing a Lost Old Account:

What you do mean by "lost"? If you no longer have your Apple Account, then it is gone. If you mean that you no longer have access to your eMail address (your Apple Account). There is not such thing as an iCloud ID. If you are using a different eMail Address, then contact Apple Support, reacting support to change your Apple Account (the email address you use). Perform a trial login session while on the phone with the Apple Rep.

Keep Personal Info Off:

For note, be certain to keep personal information (email addresses) off of these forums, as doing so, someone out there can know to whom the eMail pertains. I have asked the Moderator to retitle your thread. These forums are out these for everyone to view.
