Thanks for the info. Well, I believe the form we registered with (W-8BEN-E) is specifically for foreign entities. We do have a TIN with the IRS even though the organization is domiciled in Germany. It's a bit confusing as the organization does not show up in the search at the link you provided even when I enter the EIN... not sure what to do here. We have a lot of potential interested donors based in the USA but they have asked about tax deductibility so this is why I wanted to check. Perhaps best thing to do is to contact the IRS directly.
