The Missouri Attorney General has a charities lookup on its website. The details are skimpy and not nearly as extensive as the California AG site for finding federally approved, state registered charities and charity fundraisers. California also provides the pdf for all recent IRS Form 990’s, which is where you’ll gather the financial details and the list of highest paid employees, and the Directors. Unfortunately, none of the other online databases that track charities enable searching within the 990’s, which would be very helpful in looking for individual names. There are a number of sources that provide a free national database of charities: GuideStar, CharityNavigator and the BBB Wise Giving Alliance are a few.
