i lost my apple id recoery number

Do you have another Trusted Device that is signed into your account?

If not, the account is lost. Apple does not save the key for you, which is the entire purpose of enabling that extra security measure.

If you don't know your account password and have lost or otherwise don't have a trusted device, you need your recovery key to regain access to your Apple Account. If you can't provide your recovery key, you’ll be locked out of your account permanently.
