I want to register our NPO for Ad Grants for which registering with Google for Nonprofits is required - but although South Africa is listed as an eligible country for an Ad Grant, it says to register for Google for Nonprofits you need to be a registered 501(c)(3) nonprofit headquartered in the US. I don't get it! How do I register our SA NPO for a Google Ad Grant?
I'm not sure where you're seeing that requirement listed, but I know that you don't have to be headquartered in the US.
Here are the eligibility guidelines for this program: https://support.google.com/nonprofits/answer/3215869
You'll want to check out the section regarding South Africa.
I hope that helps!
