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.
98-1067160 questions
What is ICON PLC's EIN?
98-1067160. It comes from ICON PLC's own SEC filings record (source linked above), checked July 5, 2026. For tax filing, the authoritative copy is the one printed on your W-2 (box b) or 1099 — 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.
Where does this EIN come from?
From ICON PLC's own submissions record with the SEC (the source linked on this page) — the company states its EIN in its filings. That's the same number employees see in box b of a W-2 from the company.
