In the past, if you wanted to keep identical address books in two (or more) different Google accounts, the process was tedious and risky. You’d have to export your contacts from one, import them into another and hope that nothing got lost in the process. Then, as soon as a change happened in either account, you were out of sync once again.
With FullContact, keeping your contacts in sync across multiple Google accounts is simple. Just follow the steps below and you’ll have identical address books across as many as five Google accounts (with a Premium subscription).
You likely already have one Google account connected, but now you can add up to four more.Back to top
Once you have your accounts loaded, you can choose how you want your connected accounts to behave. In order to create identical contact listings across your multiple accounts, you’ll want to turn syncing ON for all of your connected Google accounts.
With that, you're all set. No exporting, importing, or continual updating when something changes. FullContact is going to handle all of that tedious work for you. When a change happens to a contact in one address book, it will automatically sync to your other address book via the power of FullContact's syncing abilities.
