Guidestar offers up-to-date information on the status of 501(c)(3) charitable organizations.  Their mission is to revolutionize philanthropy by providing information that advances transparency, enables users to make better decisions, and encourages charitable giving. 

If you care about nonprofits and the work they do, then you’re affected by what GuideStar does. They gather and disseminate information about every single IRS-registered nonprofit organization. Guidestar provides as much information as they can about each nonprofit’s mission, legitimacy, impact, reputation, finances, programs, transparency, governance, and so much more. They do that so that the public can take the information and make the best decisions possible. Learn more at http://www.guidestar.org
