It can be frustrating when you try to message or call someone on your iPhone, only to find their contact information is missing. Luckily, there's a good chance you can restore it. Here's what you need to know.
Restoring contacts from iCloud.com only works if they were added to the iCloud group in the Contacts app. If the missing contacts are from another provider, such as Google, Yahoo, or Outlook, they will not automatically be backed up to iCloud. Luckily, Apple adds new contacts to this group by default.
To restore missing iCloud contacts, go to iCloud.com and log into your account with your Apple ID. Click “Quick Access” in the top-right corner of the screen and select “Data Recovery” in the menu.
Check if the “Restore Contacts” card has an archive available. If it does, click it.
Unfortunately, you can't check the archives to peruse missing contacts. You'll have to make your best guess if there's more than one backup. So, click “Restore” next to the archive corresponding with the date the contacts went missing.
Confirm your decision by clicking “Restore” when prompted. You can also use iCloud’s data recovery feature to restore deleted iPhone photos, files, calendars, and bookmarks.
If your missing contacts were synced to a Google, Yahoo, or Outlook account, there's a good chance you can find the missing contacts there. All you have to do is import them to your iPhone. Then, you can check for them in the Contacts app once imported.
To do that, head to Settings > Contacts > Accounts to go to the screen where you can import the contacts.
Tap “Add Account” and choose “Gmail,” “Yahoo,” or “Outlook” in the prompt.
Follow the instructions to sign in to the account you chose. Afterward, tap “Save” in the top-right corner of the screen. The contacts should now appear in the Contacts app, and you can check if the missing ones are there.
