ISSUE 1
Contacts can sometimes become scattered or multiplied when syncing or when changing devices. To ensure that contacts are always correct, follow these few simple steps. These steps include a Mac but do not include the steps for a PC. These steps include the use of iCloud and do not require purchasing additional storage. Make sure you back up your devices regularly so you have a back up to restore from if needed.
If you are missing contacts because you recently deleted an email account, add it back until you perform these steps. If you are using iCloud you can also try going to iCloud.com>sign in>account settings>advanced>restore contacts>select from the list of "archive of contacts."
Step one
(Skip to step two if you do not own an iPhone/iPad)
On iPhone/iPad
- Go to settings>mail>accounts>tap any account and turn on contacts (repeat for all accounts).
- Go to settings>Apple ID (your name at the top>iCloud>iCloud backup - turn on and select "back up now."
- Go back to settings>Apple ID>iCloud>turn contacts off - choose to keep on device. Do not turn it back on yet!
- Go to settings>mail>accounts>tap any account except iCloud - turn off contacts (repeat for all accounts).
- Go to settings>mail>accounts>tap iCloud - turn on contacts. Stop here on the iPhone until you perform the Mac steps.
Step two
(Skip to step three if you do not own a Mac)
On Mac
- Go to system preferences>internet accounts>tap iCloud account - turn on contacts
- Go to system preferences>internet accounts> are the contacts turned on for all accounts?

- Stop there and go to iCloud.com
Step three
On iCloud.com
