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 UMSJ HEALTH SYSTEM LLC's EIN?
46-2097818, 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.

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.
