Restore contacts stored in iCloud on iCloud.com
You can restore your contacts from an earlier version that was automatically archived in iCloud. For example, you might want to restore an earlier version of your contacts to recover some that were accidentally deleted.
When you restore an earlier version, your current version is first archived in iCloud, so if you change your mind, you can go back to it.
Go to icloud.com/recovery, then sign in to your Apple Account (if necessary).
Tip: If you’re already on iCloud.com, you can also tap in the toolbar, then tap Data Recovery.
Tap Restore Contacts.
Available versions are listed by the date and time they were archived.
To the right of the version you want to restore, tap Restore.
There may be more versions than can be displayed. Scroll to see them all.
Note: Wait until iCloud finishes restoring your contacts before you change them. During the restore process, any changes you make aren’t saved.
The restored contacts and contact groups appear on all your devices that have Contacts turned on in iCloud settings.
