GuideStar (Candid)

Nonprofit data for donors, grantmakers, and businesses

Visit GuideStar (Candid)

GuideStar, operated by Candid, is a nonprofit search and research service that lets users look up IRS-recognized tax-exempt organizations, review 990 tax filings, check 501(c)(3) status, and assemble lists of nonprofits. It also allows nonprofits to claim and maintain a public profile, including earning a Seal of Transparency to share organizational information with donors.

Key capabilities include searching IRS-recognized and faith-based nonprofits, reviewing financials, leadership, and mission data, and accessing Candid's nonprofit data through APIs for integration into platforms and applications. GuideStar Pro supports research into potential nonprofit partners, while data is drawn from validated sources including 990 filings and direct reporting.

GuideStar serves both researchers seeking nonprofit information and nonprofits managing their public profiles. Profile maintenance is offered at no cost, while paid research access is available through GuideStar Pro, and API access is arranged through consultation.
