To find your Apple ID, you can check devices you're signed into, such as your iPhone, iPad, or Mac. Go to Settings on your iPhone or iPad and tap your name at the top to view your Apple ID. On a Mac, open System Preferences and click Apple ID. If you're unable to find it, visit iforgot.apple.com and enter your recovery email or phone number to retrieve your Apple ID. This is especially useful if you’ve forgotten the ID and need quick access to your Apple account details.
