An Employer Identification Number is the IRS's public identifier for a business or organization — the business equivalent of an SSN, but not a secret. You'll need it for W-2s, 1099s, and donation receipts. Knowing an EIN proves nothing about who you're talking to: never treat "they knew the EIN" as verification of a caller or invoice.

What is NSF INTERNATIONAL's EIN?
38-1428955, per the IRS exempt-organizations extract as of July 5, 2026. For donation receipts or filings, the authoritative copy is the one on the organization's own paperwork — use that if it ever differs.
Is it safe that this EIN is public?
Yes — EINs are public identifiers, published in SEC filings and IRS records, and they're routinely shared on W-2s, 1099s, and donation receipts. Knowing one proves nothing about identity: never treat an EIN alone as verification of a caller, email, or invoice.
Is NSF INTERNATIONAL a registered nonprofit?
It appears in the IRS Exempt Organizations Business Master File as of July 5, 2026 (NTEE code M05). For deductibility, confirm current status with the IRS Tax Exempt Organization Search before relying on it.
