Once your application has been submitted as a Business or Individual, you can't change your account type. If you need a different account type, you'll have to close your current account and open a new account with your preferred account type. If Google requires you to verify your identity during this process, you’ll be notified in the ‘Payments’ section of your new GAM account.
Before making any changes, please reach out to your designated Onboarding Specialist or Raptive Support for guidance.
