How to move Contacts from one sync service to another?

Select them, then drag them on top of “All Gmail” in the left column.

 

It’s super easy! But despite macOS prevalent use of drag and drop, it just doesn’t stand out to me in the Contacts app. I struggled for a while to figure it out once.

 

Do you have an iPhone or any other iOS device? Could be cause it’s sync in there too. Have you tried just exporting it and then importing it to Google?

 

Why iCloud? As others mentioned, if you have an iOS device, defaults to iCloud for save location when creating a new contact there, particularly when creating from phone app, an email, text message, etc. More control if copy a number, go to Contacts, turn off all groups and turn on the one you want, create. Messy. And why I stick to Mac for most of my contact creation.

But even on Mac, can run into same issue, depending on what group is selected. I use Smart Groups to help track down "orphan" Contacts. Once a week, visit the Smart Group and see if I need to correct things (eg. assign to a group/correct group).

Unfortunately, but makes sense, that a new contact will not be pushed to all services you have signed into.
