What if I already have a G Suite account and now want the nonprofit edition?
If you already have a G Suite account, you actually have a head start on activating the nonprofit edition. In order to upgrade your G Suite account to the nonprofit edition, you must first be signed up for G Suite basic.
From there, simply enter the domain name into the G Suite activation. Enter your domain name like this: "google.org." Do not include "www" or "http." If you don't follow this formatting exactly, your activation may not be processed accurately.
