At this time, we are only able to process donations to charitable organizations with a US 501(c)(3) status designation. We are working on the ability to process donations internationally and will update our community when we have added that capability.
Note: A few large non-US organizations, such as the Canadian Cancer Society, do have a US presence and have received 501c3 status from the IRS, so we are able to process donations to them. If they aren't already in our database (search here), you can check and see if they are eligible by checking either ProPublica's Nonprofit Explorer or IRS Exempt Organization Select Check. You can get the US-registered nonprofit added to our database by following the instructions in this article.
