Other ways to find his Apple ID

He check to see if he is signed in to iTunes for Windows on a PC. He can also go to iCloud.com or appleid.apple.com and see if his Apple ID prefills on the sign-in screen.   

If he forgot the Apple ID (iCloud) password, enter the Apple (iCloud) ID, and click Forgot Password. See if he can get a Rescue or Notification email option if necessary. Link to contact Apple Support at the end of the 2nd article.
