Yes, it's Red Cross. I received a missed call, they left a very professional voicemail letting me know it was Red Cross and that they wanted to confirm some details, and that they'd try again later.

I have some missed call from this number, I recently did some donation to doctors without borders.

a strange number

there must be an organisation that co ordinates donations, I am getting calls from this number (and very similar numbers) and have recently donated to Fred Hollows.

Well I joined Amnesty International, must be some kinda charity call center cause when I rang back their voice mail message doesn't list an organisation at all, So I just left a message that I missed a call and the voice mail doesn't state who they are so I won't leave my contact info with out hearing what organisation the voicemail belongs to. I'm sure it's fine, but they should have a more professional answering service!

This is an Australian number. I was called from this number regarding my Red Cross donation. Do you do any donation to Red Cross? That might be the reason they called you.
