From January 2017, Google Ad Grants required all Ad Grants accounts to request a Google for Nonprofits account. Since that time, notification emails have been sent to the login email addresses of affected Ad Grants Google Ads accounts with instructions to complete the request before April 30, 2017.
Accounts that did not request a Google for Nonprofits account by April 30, 2017 have been temporarily deactivated. If your account was affected, you'll have received an email at the login email addresses in the account. To reactivate your temporarily deactivated Ad Grants account, complete the request for a Google for Nonprofits account by following the steps below. When you receive confirmation that your organization has been verified, your Ad Grants account will be automatically reactivated within 24 hours.
