A Google verification code is a short numeric code that is sent directly to you, usually via phone or email, to verify your identity. You might need to enter a verification code if you try to create a new Google account, reset your password, or log into a different computer or device.

"This phone number cannot be used 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 accounts each phone number can create. You can use a family member or friend's phone number instead.

At the top, tap Security. Under "Ways we can verify it's you," tap Recovery phone. Follow the steps on the screen to re-add your number. To keep using your number in other Google services, go to those services and re-add it.
