Delete a contact on iCloud.com
Note: If you don’t see the groups list in the sidebar, try viewing your iPad in landscape orientation.
You can delete a contact completely from iCloud Contacts or remove it from a group.
WARNING: When you delete a contact, it’s deleted on every device that has iCloud Contacts turned on.
In Contacts on iCloud.com, do either of the following:
Delete a contact completely: Select the contact in the All Contacts list. Tap the Action pop-up menu in the sidebar, choose Delete, then tap Delete.
Delete a contact from a group: Tap the group on the left, then select the contact. Tap the Action pop-up menu in the sidebar, then choose Delete.
Deleting a contact from a group removes it from that group only.
If you accidentally delete any contacts, you can use iCloud.com to restore them. For instructions, see Restore contacts, calendars, and more in Settings on iCloud.com.
