How can I lookup the business associated with a FEIN?
I think much of that info is hidden behind pay-walls.  Here is one site I've found. http://www.feinsearch.com/ Another that is for non-profits only is guidestar. http://www.guidestar.org/rxg/products/nonprofit-data-solutions/product-information/guidestar-premium/advanced-nonprofit-search.aspx
