What if I already have a G Suite account and now want the nonprofit edition?
If you already have G Suite, you actually have a head start on signing up for the nonprofit edition. In order to enroll in the nonprofit edition, you must first be signed up for G Suite so Google can upgrade your domain name.
If your organization is already signed up for the G Suite, simply enter the domain name into the G Suite enrollment form and submit it. Enter your domain name like this: "google.org." Do not include "www" or "http." If you don't follow this formatting exactly, your enrollment may not be processed accurately. Learn more about the nonprofit sign-up process.
