Hello JA Customer
Federal ID numbers are protected by the Privacy Act, the same as social security numbers. They are not available anywhere as part of public records.
Unless this organization volunteers to give you their federal ID number, no one else at the IRS or anyone else is authorized to give out this info or even has access to it.
I know this doesn't give you the information you asked for, but hopefully it keeps you from going on a wild goose chase looking for this number, because it is not part of public records.
