Re: How do I re-enable my organization's gmail account?
Ask a "how to" question
: Account Access and Safety
: Google Chrome
Google isn't interested in the "age" of an organisation or club. All it needs to know is that the PERSON who operates the account is over 13, in order for Google to stay compliant with legislation re minors.
So follow the instructions you have been given and use your own credentials to prove your age.
