I am pretty sure the answer is obvious but I thought that I would ask my fellow Blackhatters. I am starting to bank with different affiliates and now I need to provide either my SS# or an EIN. I realize that the EIN is easy to get. The question is, is it "safer" to use a EIN? I don;t really feel comfortable providing my SS#. Also, as far as taxes go, will there be a difference in using the two? Are you more under the IRS radar with an EIN?
