Here at GuideStar we gather and disseminateinformation about every single IRS-registered nonprofit organization. We provide as much information as we can about each nonprofit's mission, legitimacy, impact, reputation, finances, programs, transparency, governance, and so much more. We do that so you can take the information and make the best decisions possible.

Organization Mission

We encourage nonprofits to share information about their organizations openly and completely. Any nonprofit in our database can update its report—for free. We combine the information that nonprofits supply with data from several other sources. You'll find GuideStar data:

  • on this Web site
  • on our many client and partner Web sites
  • in computer applications used by funding entities and private companies that work with nonprofits

Many people think that we are a charity evaluator or a watchdog. We aren't. Instead, we are a 501(c)(3) public charity that collects, organizes, and presents the information you want in an easy-to-understand format while remaining neutral. Providing nonprofit information to a broad audience at no cost to those users is an important part of our public service, one that we pledge to continue.
