Where the records come from
Three public federal filing systems. Every fact on a result card names the one it came from and the date of the file or filing.
IRS Exempt Organizations Business Master File
Every organization the IRS recognizes as tax-exempt: EIN, name, address, subsection, ruling date, deductibility, foundation classification, latest filing period, and financial codes. Published monthly under Internal Revenue Code section 6104.

Department of Labor Form 5500 and 5500-SF datasets
Annual filings for employer benefit plans: sponsor EIN, name, address, plan name and number, participants, plan features, administrator, and the date the Department received the filing. Public under ERISA section 104(a). One-participant plans file a different form that is not public and is never inferred here.
SEC EDGAR company submissions
Every company that files with the Securities and Exchange Commission: EIN, name, former names, state of incorporation, industry code, ticker, and latest filing. Individuals who file as insiders are excluded.
