You can't change your Google Account number. Your Google Account number is actually your email address.
Here's why:
- Email is your identifier: Your email address is the primary way Google identifies your account.
- Security: Changing your account number would compromise the security of your account and make it difficult to recover if you forget your password.
If you're looking to change your email address associated with your Google Account, you can do so by following these steps:
- Sign in to your Google Account.
- Go to your Account settings.
- Click on "Personal info."
- Select "Email."
- Enter your new email address and follow the on-screen instructions.
Important: You'll need to verify your new email address before it becomes your primary account address.
