Apple account email address verification - “unknown error has occurred”

I am trying to login to my iCloud account, but get asked to verify my email address. No matter which email address I use (@mac.com or other primary address) I get an error message saying “an unknown error has occurred”. This happens on iPhone and iPad, as well as over WiFi and mobile data. My devices are still linked and synching to iCloud and running the latest iOS.


Apple chat support have been unable to help and my planned callback hasn’t happened so would appreciate any ideas to fix this!

Your Apple Account is the account you use to access Apple services like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more. It includes the email address and password you use to sign in as well as the contact, payment, and security details you use across Apple services.


The email address and password you used to sign in here to the community, should also work with iCloud. If not: Below are a few suggestions.

If you haven't already:

(1) Restart your iPhone: (deletes temporary files, re-establishes connections,

may update recent setting changes etc., and often restores order if something is not

working as expected.

(2) Try checking you are signed in to your iPhone with your correct Apple Account details, and see which email address is your primary email address to use with iCloud.
