What a result can and cannot prove
An EO BMF match means the organization appears in the IRS’s cumulative exempt-organization master file for the selected state file. The deductibility field is the IRS’s indicator used for eligibility to receive tax-deductible charitable contributions; a match here is not a donation receipt or legal advice.
This is not a universal private-business EIN directory. The public IRS data is for exempt organizations. For a 501(c)(3) donation check, also review IRS Publication 78 bulk data ↗ and the organization’s current IRS record. Status, filings, revocations, and deductibility can change.
Worked example
Choose DC and enter 53-0196605. The IRS EO BMF returns American National Red Cross, Washington, DC: subsection 03 (501(c)(3)), deductibility code 1 (contributions deductible), status 01 (unconditional exemption), ruling date 1938-12.

FAQ
Is an EIN lookup the same as checking 501(c)(3) status?
No. An EIN is just a 9-digit identifier. A record in the IRS Exempt Organizations Business Master File (EO BMF) shows the organization's exemption subsection, deductibility code and status. Subsection 03 means 501(c)(3). Confirm time-sensitive questions in the IRS Tax Exempt Organization Search.
What does the deductibility code mean?
In the IRS EO BMF data dictionary, code 1 means contributions are deductible, code 2 means contributions are not deductible, and code 4 means contributions are deductible by treaty (foreign organizations). A blank field means the IRS file does not supply a code.
Why does the tool ask for a state?
The IRS publishes the EO BMF as one CSV file per state or territory, organized by the organization's filing address. Pick the state of the address on file, which can differ from where it operates.
Can I look up any company's EIN here?
No. The public IRS data covers tax-exempt organizations only. It is not a directory of private business EINs, and the IRS does not publish one.
What if an organization's exemption was revoked?
Organizations that do not file a Form 990-series return or notice for three consecutive years lose exempt status automatically. The IRS publishes that list separately from the EO BMF, so check the automatic revocation list before donating.
