We work with several partners to enable donations to non-US charitable organizations. Any organization showing up in our database search results is eligible – although international organizations are subject to periodic review and eligibility isn't permanent. Additionally, we generally require $500 in accumulated donations before making a payout to an international organization, due to minimums required by our partners.
Some large international charitable organizations are also registered in the US, and we can send donations to their US affiliate directly. For instance, the Canadian Cancer Society has received 501c3 status from the IRS, so we are able to process donations to them.
We are working on expanding our international donations reach and will update our community when we have added that capability.
