Is there anyway to recover an iCloud email address without knowing your Apple ID?

Welcome to the Apple community.

Your iCloud email address is your Apple ID. You may be able to find your Apple ID at Look up your old and forgotten Apple ID or see if any of the tips on this page help.

When you create your iCloud account using a third party email AppleID, then your @icloud.com becomes a synonymous login for your AppleID. And if that iCloud account brought along any old @mac.com or @me.com email addresses with it, then all of those are synonymous login IDs for your AppleID.

Not necessarily. Mine is not. My Apple ID is a Gmail address but I also have an iCloud email (which I rarely use).

Your iCloud email address will also act as your Apple ID. My primary address is steve at my own domain, but my iCloud address works too. Try it at iCloud.com

Well, thank you both. I wasn't aware of the quirk. Most of the time, I can't remember the address and have to log into iCloud to find out what it is.
