Google allows its users to set up an unlimited number of Gmail addresses. You can manage all of your Gmail addresses in one place through your Google account, which makes it easy to stay organized. There is a caveat though: You'll be limited to four total Gmail accounts linked to the same phone number.

You can add both Gmail and non-Gmail accounts to the Gmail app for Android. On your Android phone or tablet, open the Gmail app . In the top right, tap your profile picture. Tap Add another account.

"This phone number has been used too many times for verification" If you find this error message, you have to use a different number. To protect you from abuse, we limit the number of times a phone number can be used for verification. You can use a family member or friend's phone number instead.
