How to Get Your Nonprofit Listed on GuideStar | GuideStar
GuideStar automatically lists all 501 (c) nonprofits registered with the federal IRS. To check if your organization is already listed, enter its nine-digit Employer Identification Number (EIN) into the GuideStar search. Please make sure to include the dash (-). However, if your organization has only recently received tax-exempt status from the IRS, it may not be listed on GuideStar yet.
