Avoid billing prompts
Please do not submit any billing or payment information at any time. You might see automated messages in your AdWords account or via email because non-profits create accounts through the same interface as paying advertisers. Skip this section in your account setup and ignore any messages or notifications encouraging you to submit payment information in order to activate your account.
Instead of entering payment information, Google Grants accounts will be activated by the Google Grants team once the completed account is submitted for review and has been approved.
